[Max] I need help! / Real size map or UVW !
« on: 2023-02-15, 14:04:31 »
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

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

Hardware / I NEED HELP with a PC build
« on: 2022-11-16, 10:08:44 »
Hello

I want to build a new PC and I only work with corona renderer and 3dmax, nothing else at the moment. I got fired from 2 jobs for being impatient so waiting for the first 4 passes to render made me realize that they were right to do so.
My current device I have a G14 Zephyrus Laptop with an AMD Ryzen 9 4900HS with a Radeon Graphics 3.00 GHz processor and an NVIDIA GeForce RTX 2060 GPU, with 40gb of RAM.
I don't like the performance when I have to deal with big scenes, the viewport takes forever and the render too, but with small scenes ( one room for example ) it does a good job. Now I want a PC that can run any viewport smoothly and render any scene faster than I can realize I chose the wrong camera :D

That's not all, I want all that with a budget of 3000$ only.

Seriously, I watched a lot of youtube videos trying to figure out what to buy, but honestly, I got nothing, I don't trust my knowledge to decide. I am an archviz who is just starting but I already have a ton of work to get done so I am thinking of getting a powerful PC that can serve me for years. I only use corona renderer so I get confused when I hear about GPU and their importance, do I need a powerful GPU when using corona?
what is the best CPU for my case ?

Thank you

Hello

 I come by this problem a lot when doing interior, some shot needs to be more exposed and i hate going back and fourth when chagning cameras

Thank you

Hello

Like most artists, I set up light first while mtl override is on, then proceed to materials. The new slicer mtl has become an essential part of my workflow since i started using it for windows and cutting holes for artificial lighting fixtures, so i thought adding it to the preserve list would be great since it serves the purpose " overriding mtl for setting up light".

Thank you
