[Max] Daily Builds / Re: Chaos Corona 13 for 3ds Max - Daily Builds Discussion

« on: 2025-06-19, 14:41:40 »

I can quote Alex's really good suggestion of running internally downresed input so the user can have the primary image be native high-res and AI enhancement up-resed.

I still miss the internal AA down-resing from Corona Alpha :- )

Oh the internal AA down resing, that was before my time - is it at all similar to what is shown in this recent video?

(basically, render to 2x resolution, then downscale to final image size). This is an idea I am considering putting on the cards for development, basically skipping the Photoshop step of downsizing, so am interested to hear thoughts.

I've learned this trick from Juraj, back in the early days of corona, and yes, I think this could be easily incorporated into daily builds.
some like "render 2/3x bigger and downscale it" option, for final output.
+1
So, basically corona will become 5-10x faster within one single click, with 2-5% loss of details, maybe not even closer.
My advice is HURRY UP, as you slightly loosing the speed battle against GPU renders...
With this little improvement/ hack you are in the game againa...

Pain started a year ago, from december 2023 every version is worst.

So, you are on Corona 11 still?
What is latest stable do you use?
Thanks!

[Max] General Discussion / Re: Rendering Slower with Sun / Sky vs HDRI

« on: 2025-04-19, 22:51:27 »

Hello,

I have noticed that rendering with Corona Sun/Sky is a lot slower than rendering with an HDRI. Why is that? I would of thought it would be the reverse.

Me too, I did not make the tests, but the difference is noticable.
Perhaps, it is not about the Sun, only the Sky cause the render to slow.
You can use both Sun+HDRI, and it works quit fast, too.
Cheers!

Do not care about "realism" unless it looks good.
for VFB with zero exposure Sun is about 0,05-0,08

Hardware / Re: GPU - 3ds max

« on: 2025-04-01, 14:28:40 »

In my experience it doesn't really matter much in regards to the viewport, my 1060GTX is on par with my 3080RTX. Probably some 3dsmax bottleneck. (both Laptop variations by the way)...

Could you write on more this please?
What kind of scenes do you work on, so those 2 video cards work similar?
Interiors or some heavy tree exterior?
3dsmax use CPU, single thread, for viewport as well as GPU
in ratio, lets say 40-60, roughly said...

Also, D3D 11 is much slower than D3D 9.
Which version on Max do you use?

[Max] Tutorials & Guides / Re: 3ds max + Corona + Windows = Finally good performance

« on: 2025-02-27, 12:00:23 »

Hello everybody!

I've opened this thread only to share this few basic tips which are a result of two years of problems and recently improved my performance drastically.


[short introduction]

I've just opened an account on this forum just to tell you this important information regarding performance. I've been using Corona as my main work tool since version 1.2. I work as an interior designer and Corona has become my main tool even though I am very skilled in Vray. Over the years I've been having CONSTANT problems with various versions of 3ds max and Corona and of course - windows. Many don't understand how many bugs are produced by bad 3ds max architecture (nothing to do with Corona), and even worse bugs are produced by windows. Like many, i just need things to WORK because my business depends on it. Every one of this tips has been tested and verified over and over and trust me, I have had crazy 12-hour full exterior overnight projects and I really know what I'm talking about.


[technical tips]

-I will start by saying: if you use Corona and 3ds max you absolutely HAVE TO use Windows PRO , not home and lower variants.

-(most important tip)- DISABLE windows defender, DISABLE firewall. Now, I've done this years ago in windows defender and in control panel and it didn't work. It's very important to do this by group policies editor in Windows pro and up and/or via registry editor. Only that way will completely disable it.
Explanation: it solves the most annoying performance hitter which is (LONG) waiting every time you start up 3ds max, close 3ds max, start rendering, stop interactive or regular rendering, loading maps, merging files, etc etc... This will save you so much time its crazy. Windows architecture is set up in a way that somehow has to scan and check all the files that come in through RAM and that is the main reason for slow performance.

-in my experience, 3ds max 2017 and 2018 were the last versions in which i am able to reach peak performance. Later 2019 and 2020 have issues admitted by Autodesk and not yet fixed. The improvements do not outweigh the problems.

-you don't need to use 3ds max as administrator, it gives you problems when merging files.,


These tips finally gave me the perfect experience. No crashes, no waiting, just work. Hope it helps.



Specs:

Threadripper 3970x
256GB ddr4 ram
2x1TB nvme samsung 970 pro raid

For all those who missed this LIFE SAFER topic, I am bumping it...
I tried most of advices here...and now I can go to coffee!
As at least 30-45mins you will get per day, if you work 8-10h
it is hard to calculate ofcourse, but all those waitings are now GONE FOREVER.

It is literally like upgrade from Coppermine PIII to C2D.
when working in 3dsmax, max is responding IMMEDIATELY, almost...!
Thanks everybody for writing in this topic...Cheers!

General CG Discussion / Re: TIP - 3dsMax > Display Performance - Don't set these values too high!

« on: 2024-12-19, 18:20:42 »

This is super important, so good for bringing it up!

I never tested the speed of opening, but I routinely use 4096px and my scenes open fairly quickly. I am tempted to believe the slow-down would be rather due to swapping between GPU VRAM and System RAM. 11GB of 2080ti is still not a lot, because 3dsMax doesn't use any compression at all, so single bigger scene can eat up to 10GB in textures alone and that is just viewport in Max alone, Photoshop, Web Browser, Image viewers,etc. will eat VRAM at same time.
(But now I am gonna test this up)

I have other "trick" people might not know with Corona, CoronaBitmap doesn't use TextureSize like Max Bitmap, but the procedurals! I was baffled why my CoronaBitmap materials look blurry in viewport and Ondra explained it's due to this.

1. What 3ds max viewport like the most is CPU speed! With same GPU but with faster CPU it will be space rocket upgrade!
1a. for those with 11/12GB GPUS, lower the tex size to 512px, it will work like RTX 3090! no joke!

2. What is the solution for the blurry corona bitmap in viewport?

General CG Discussion / Mess with MassFx/ Physics plugin garbage...

« on: 2024-05-02, 12:38:39 »

Sometimes it is very hard to fight with hidden MassFx/ Physics plugin garbage, although you already have updated plug-in installed, etc...
Those 2 scripts may help to clean up the scene, but please, be aware, as the changes are not reversible, so save the scene before starting the script.
I collect them randomly on the net...and it is always good manner to start the script from *.ms file, not maxscript listener...

2 scripts....

(
fn hasMassFXMod o =
   (
   result = false   
   if o.modifiers.count > 0 then
      (
      for t = 1 to o.modifiers.count do
         (
         if (classof o.modifiers == MassFX_RBody) then
            result = true
         )
      )
   result
   )   
     
clearSelection()
   
for obj in objects do   
   (
   if hasMassFXMod obj then
      selectMore obj
   )
)






pxStuff = #(UConstraint, pxJoint, Skeleton, nvRagdoll, nvBox, nvCapsule, nvSphere)
for i in objects do for j in i.modifiers do if (classof j==MassFX_RBody) do deletemodifier i j
for i in objects where (finditem pxStuff (classof i))>0 do delete i

General CG Discussion / Re: Reset Xref/Collapse/Edit Poly

« on: 2024-01-04, 23:51:12 »

Hi,
I am SO sorry to be one of those annoying-people-you're-helping-with-nothing-in-return... BUT
Please see attached screencapture.
Either I'm doing something wrong, or something buggy is up with my max. Either is very likely...
Can you spot a problem? Thanks again James you're skills are impressive

Do not worry, me too!
I have some ideas for scripting, to speed up workflow

1. use some batch merge script /there are a few of them/
2. explode and attach every file imported via batch merge script.

Basically, we should combine functionality of 2 scripts, merging, and attaching into poly.

merge
https://www.scriptspot.com/3ds-max/scripts/batch-merge
and soulburns attachselectedobjects
with pivot in center base, ofcourse!
furher more, we could incorporate multialign script to align them into raws...
and with few clicks, you have whole afternoon of work.

I hope I was clear enough what did I want to explain.

There are a lot of cleaner scripts, which clean note track, among all garbage....but so far I did not find any script which makes better job than this one note tracks cleaner...
It it is real life saver....

If you do not have 3DSky account, here is the script
