[Max] I need help! / Re: Real size map or UVW !

I get this result by selecting the horizontal faces and apply another UVW map then rotate, is there a better way ?

James Vella already explained everything, i just add one more way how to quickly edit UVW mapping on selected faces. First you need to go to polygon sub-object mode, select all the faces that you need to alter, add UVW xform modifier on top and rotate, tile, or offset UV coordinates. As long as apply to entire mesh checkbox is inactive, the modifier will only affect UVs of selected faces.


That's really helpful, never used UVW xform before
Thank you so much guys

Enabling this means that your bitmaps and uvw modifier use real-world settings by default so you don't have to manually turn them on every time you import the bitmap or apply the modifier. Saves you a few clicks I suppose, I would still use box instead of planar mapping but handy regardless.

Quote
Also when creating/extruding shapes by default it enables real-world mapping so you dont need to even apply the UVW modifier. Same goes when creating Boxes/Spheres etc.

I checked the option and it works as you said, except when I extrude a polygon of a box the map stretch and I have to apply uvw modifier, is it supposed to be like that even after checking the real-world coordinates option?

Quote
This is creating the object in front view, now I have to select the edge faces to rotate them. This technique applies to many things in 3dsmax like when doing sweeps/lofts etc.

that's very good know, I always that the software is acting up when this happen to me :D

Quote
The main benefit really by using the Realworld mapping option means that in the long run once you save all your materials to a library you are basically just creating shapes/extruding, slapping on the materials and you always know it will be the correct scale and/or direction so you dont need modifiers, dont need to double check scale etc.

Yes I already started modifing my library :d
Thank you for your help, I learnt so much

If you work in architecture then real-world mapping is the way to go in my opinion. It saves you countless hours over the years when you have set up your materials as per the size you require. Also if you have other textures that use similar parameters (tiles for example) then when you create these textures you have a reference size/resolution.

I guess because whoever authored the fingerprint texture didn't take the resolution/real-world size into account or maybe doesn't apply to their situation. You could also contact the author and ask I suppose.

So now I am excited to use this method cause it seems better, because I only need to add one UVW Map to an obecjt even if I have 3 or 4 materials
Then this is really going to blow you socks off :)
Customize > Preferences > Texture Coordinates > Use Real-World Texture Coordinates. Have fun :)

what does this option do ? I only make materials for walls, closets, tables, kitchens, doors ..etc only simple models that I do myself, when it comes to sofas and chair or other complicated models, I just buy and use them as they are, only changing the hue and saturation If I need. < I tried to understand unwrapping once, I couldn't so your discution with romullus is above my level   :D

Thank you

Both methods are correct and you can choose which one to use basing on situation and your personal preferences. You can even mix them in the same scene and in the same material. even more, it's ok to use RW texture on a non RW mapped object and vice versa. In fact both mapping methods are essentially the same, the only difference is that with RW mapping the scale is managed automatically. And that's it. RW mapping is very useful in archviz where the same tiling texture must be mapped on multiple objects of different sizes and proportions - you simply don't need to worry about the scale. On the other hand it won't work on objects unwrapped to 0-1 UV space that uses bespoke non-tiling textures.

Also, when I buy a map like fingerprints or dirt, why don't they give real world size so we can apply it ? I find this confusing even with some albedo maps, eventually I will set it to how I see fit but I am just wondering!

In many cases real texture scale doesn't matter much (your mentioned fingerprints and dirt exactly falls into that category), in other cases vendors simply don't know, or don't care to give real world scale. Serious assets providers like Megascan will always provide scale information with their assets, along with other useful info.

I will use real world size from now on, much faster in my case.
I only do archviz, so a fingerprint on a glass has to be the right size and it would be great if knew exactly the size instead of eyeballing it.

Hello

So it has been 14 months since I started learning 3dmax and corona, and I have always apply materials to objects then apply UVW map modifier on them and set the size of the map to the size I see close to reality, like this : https://ibb.co/KywRGNX


I was watching a tutorial in YT where they done it differently, they gave the map a real world size and apply UVW modifier and set it to box then checked real world size. see here : https://ibb.co/9Yn6kXp


So now I am excited to use this method cause it seems better, because I only need to add one UVW Map to an obecjt even if I have 3 or 4 materials

So I am here telling you this because I have a feeling someone would explain to me why the easiest method ( the second ) is wrong or something like that, I can't believe all courses I took and tutorials I have watched have not mentioned that, or they have but I was focusing on my first method
Or maybe someone would point me to a better way ?
Also, when I buy a map like fingerprints or dirt, why don't they give real world size so we can apply it ? I find this confusing even with some albedo maps, eventually I will set it to how I see fit but I am just wondering!
Thank you

Hello

Is there anyway to see the material selected in CoronaSelect mtl in the viewport ?
It shows up as gray

Thanx

Or, check your bump mapping, is the bump somehow creating the effect?


This was it, I don't know how the bump was doing this even though both sides were one object and one material but I turned off the bump and it was fixed
Thank you

My first guess would be that the light is a different distance from the wall. Make sure they're both exactly the same distance from the wall they're casting light on.

the second image shows the result when turning off UVW map modifier while both lights are still in the same position, so no it is not the distance

Hello

Attached is the render beside the setup for two instanced lights that appear different in the render
I turned off UVW maps modifiers and seemed to fix the problem, which made me more confused !!

Any ideas ?

Thank you

Hello

I have seen some old tutorials explaining how to use corona ray switch material for glass for faster rendering, I tried rendering with and without RSM and the result are pretty much the same.
I was wondering if it is still needed or not ?
Also, I have tulle material, that actually slows up the interactive a little so I was wondering if I can use ray switch material with it?

Thank you

I built my computer yesterday!
Corona Benchmark: 00:00:36!!!

Yes I had the same results, but now that I have built my pc, I don't care much about benchmarks. I am so happy with the interactive rendering speed and the final render time
For GPU I went with RTX 3090 24gb

With the 7950x I've been reading that you'd be fine with almost any cooler. It keeps 95 deg and regulates the performance. But the difference in performance are minimal.

I read that too, but I also read about the effect coolers have on CPU performance and it is quite noticeable. This is my first build so I have wait and see.

 
Well, the general opinion that swayed from "The chip will burn" to "fine with any cooler" is quite extreme :- )

Of course the chip won't burn but throttle but performance difference won't be minimal at all in multi-threaded performance.
There is big difference in general use (games, media) where few cores can clock very high leaving the rest docked or clocked lower and thus maintain high performance (FPS,etc..) despite overall throttling, but mixed workflow like Corona Interactive will suffer lot more.

Powerful cooler is always good idea and there is reason why coolers are rated for some particular TDP (Noctua has the best publicly available list of this).
Even when you power limit (or/at same time voltage limit) keeping the CPU well cooled maximizes your performance. You paid a lot of money to leave it on the table.

Reason to avoid Enermax is because they have the highest fault-rate in industry. If you have 3000 USD PC, you don't want your liquid cooler to grow shit inside, lean or just explode the pump outright.
They simply produce crap products, it's that simple.

Unfortunately, the product already has been shipped, so I will have to use it for now until next month when I can buy a better one. I have my eyes on this one ( https://www.newegg.com/p/13C-0005-002A0?Item=9SIAADYH270112 )
I have to say I am a little bit confused, you recommended I get an AIO and Noctua D-15, I don't know how they fit together because I thought AIO also has CPU cooling, can you explain?

Personally, I bought noctua. I still have aversion to water in my case.

Everything's coming next week. Will report back.

So far my build is:
7950x (B&H sold it for $550!)
Gigabyte B650 Aero g
Noctua nh-d15
2x Kingston fury beast 64GB 5200Mhz
2x M.2 Samsung 980 pro (1TB for OS and 2TB for projects)
Case: fractal torrent mid tower
Psu: Corsair HX 1200w platinum


I'm reusing a gpu from a previous build.




Close enough to my build, waiting for your take on the cooler

I would say do not buy anything from Enermax, esp. when it comes to AIOs.
AIOs in general had lot of bad rep lately (from non-Asetek sourced pumps), but Enermax is legendary for their poor track record.

Buy some of the market staples:

Air: NH-D15
AIO: Arctic Liquid Freezer II (This is the best AIO on market due to thicker rad) 360/420, or any of the popular Asetek models (NZXT, Corsair, EK, etc..). No really, buy the Arctic :- )

Even laptop integrated GPUs have smooth 3dsMax viewport, it's very little affected by GPU power. The important is to not run out of VRAM, so 8+, ideally 12+ GB GPU card is good otherwise you will be limited to 1-2K textures in viewport look and single 3dsMax instance open.

I am glad you scored a deal for the 7950X :- ) ! That was probably the only authentic Black Friday shit lol.

I thought AIO cooler is enough, what do you mean by AIR ?
I already purchased the list above along with the Enermax AIO, since I already bought i would give it a shot but do i need anything else regarding cooling ?

Okay so i will go with 3060 12gb GPU, hope it is enough

The TUF is an ok motherboard. I haven't checked the vrm but I think it is ok for the 7950x and I guess you won't be overclocking.

Yes, you would need ddr5 since 7000 series CPUs don't support ddr4, and if you plan on going 128gb ram at some point get 32gb ram sticks so you can upgrade from 64 to 128 by just adding 2 more sticks.

NH-D15 is their biggest cooler so it should be ok. Make sure to get a case that supports the height of the cooler heatsink+fans. A really good case is the Fractal design torrent. It is a bit more expensive but the quality is outstanding and the airflow is fantastic!
I have one and I am really pleased with it.

As for the monitor I could give you 10 recommendations but it would be great if you can give an estimated budget/price range for the monitor.

Best,
V


I was afraid I would miss the 7950 deals so I made a purches for most parts expcet for the case, moniter and GPU
here is the list :
SAMSUNG 980 PRO M.2 2280 1TB PCI-Express Gen 4.0 x4, NVMe 1.3c Samsung V-NAND 3-bit MLC Internal Solid State Drive (SSD)

ASUS TUF GAMING X670E-PLUS WIFI 6E Socket AM5 (LGA 1718) Ryzen 7000 ATX Gaming Motherboard (16 Power Stages, PCIe 5.0, .
Refurbished: CORSAIR RMx Series (2021) RM850x CP-9020200-NA/RF 850 W ATX12V / EPS12V 80 PLUS GOLD Certified Full Modular < I just notcied the word Refurbished when copying, hope it turns out okay

As for the case and the monitor, I have to stick with my local options which are limited.
A case i found for a 100$ is called Lian li lancool 2 mesh, I couldn't decide on how the components fit into it so I have not bought it yet
I also found a monitor called odyssey g7 curved ( lc27g75tqsmxue ), Is it good for archviz ? it is not exactly cheap ( 600$ ) but it is not gonna cost an extra 130$ for shipping because it is available locally. So you can say my budget is 400-450$ if you can recommend a better monitor

As for GPU, what do you think is the sweet spot for a gpu that can navigate 3dmax veiw port smoothly when working on big scenes ? < my definition of big scenes is around 20m polygons
Is the 3060 a good option still ? I rather not pay more than I definitely need for GPU, budget is tight

Thank you so much for your help

I would most definitely advise going the 7950x route. The 3000 Threadripper is basically a dead platform now. It is already more than 12 or so months that I can't find a single trx40 motherboard in a 600km radius around my location :).

Haven't yet tried the 7950x but for the past few months, I find myself sitting always in front of a 5950x workstation and just turning on the DR server on my 3990x workstation. The snappiness of the 5950x system is just way ahead of the 3990x and it is so noticeable that I might just send all the TR systems to the farm and change most of the ws machines with the newest 16core Ryzens or Intels. Though I am leaning more toward the 7950x since it is more efficient than it's Intel counterpart.

As for your build go for the AIO rather than the Hyper 212 just check the am5 socket compatibility. The CM cooler isn't really suited for that wattage so a 360 or 420 aio should be ok. The X670E motherboards are overkill and only if you need PCIe gen 5. If you want to save some money you have the same Strix board with the B660 series which is quite good.

I could not find a B660 motherboard for AMD chip, but I found some options:
 TUF GAMING X670E-PLUS WIFI Gaming Desktop Motherboard - AMD X670 Chipset
Asrock B650 PRO RS AMD B650 AM5 ATX DDR5 Motherboard


Someone mentioned the DDR5 and I must go with a motherboard that supports it, and I don't care about PCIe gen5 ( I didn't even know what is it till I looked it up after your reply ) :D
As for the CPU cooler, is Noctua NH-D15 good ?

what do you think ?
Also, as an archviz, what to look for when shopping for a monitor ?
Thank you all for your help

Have a look at the few threads in this section that discuss Ryzen 7950X and Intel 13900K builds.

These are the best two builds you will be able to buy today. Don't look at Threadripper with your budget, it's generation (or two) behind already and very cost inneffective.

I was thinking of getting the best I can even if I increase the budget, but that only if it is completely worth it. So as you guys suggested I will not be thinking of threadrippers anymore.
Ryzen 7950x seems good for me based on what I read.
For the GPU, for 3dmax/corona workflow as an archviz, what would you suggest?



I don't even think you can get a 3xxx series Threadripper anymore and if you do it is probably going to be really difficult finding a motherboard for it - seems like everything went EOL really quickly. There might be a SIs still sporting a few though.

I do agree with Juraj, 7950x or an 13900K build seems to be quite the sweet spot for your budget. The next gen (although previous gen compared to consumer parts, Zen 3 vs Zen 4) Threadrippers are now PRO only which means you'll get a ton of PCI-E lanes you don't really need for rendering and it will cost you quite a bit. These are still the way to go if you are after top notch performance but they will be quite a bit more in that "workstation" pricing tier that is just a lot more expensive than what you get on the consumer side with the above suggested CPUs.

In case you do want to do the math, the 5975wx is the 32 core Threadripper now and the 64 core one is the 5995wx.


Thank you for your insight, I decided on 7950x. I am overwhelmed with so much information from the digging the past two weeks, I don't know how to connect the dots to come up with decisions regarding the rest of the parts.
Yet, I added these products to the shopping cart, to be ready for the black Friday, here it is :

CPU : AMD Ryzen 9 7950X 16-core 32-thread
RAM : Crucial 64GB (2 x 32GB) DDR5 SDRAM Memory Kit
SSD : Kingston 2 TB Solid State Drive - M.2 2280 Internal - PCI Express NVMe
SSD for system : Seagate FireCuda 520 1 TB Solid State Drive - M.2 2280 Internal - PCI Express NV
Motherboard : Asus ROG Strix X670E-I GAMING WIFI Gaming Desktop Motherboard - AMD X670 < youtube recommendation, I don't know if it is too much or not
Case : Fractal Design Focus 2 Computer Case
PSU : Corsair RMx Series RM850x - 850 Watt 80 PLUS Gold Fully Modular ATX PSU

Also I added two products for cooling but I don't even know if it fits or enough :
Cooler Master Hyper 212 RGB Black Edition
Enermax LIQMAX III ARGB 360 ELC-LMT360-ARGB Cooling


what do you guys think ?
