Hi, how exactly do you copypaste the asset from one Max to another?

The simpler reproduction steps are:
- save anything in .cxr format in any version of Corona
- open with v14 CIE
- save with v14 CIE

:)

This is now reported as (Report ID=CMAX-1864).
Thank you!

[Max] Bug Reporting / Re: Memory leak

« on: 2025-08-28, 17:54:30 »

I think the crazy RAM usage here is the result of a few things in the scene, but they all seem to be related to the Legacy Mtl. For example, if you lower the Legacy Mtl's Fresnel IOR from 100 to the default 1.52, then it renders fine. Also, if you isolate either of the objects, it renders fine (even with the "wrong" materials and render settings).

Since the Physical Mtl is here to replace the Legacy Mtl and it already contains various fixes, I don't see a need to log this for the devs.

I tried with various CPUs, with V13 HF1 and the V14 daily and I am getting the expected results. Can you try with a lower number of threads used? For example 50% only.

One thing to note here is that "16 out of 32 threads" here doesn't mean that you will see only 16 logical CPUs working at 100% in the Windows Task Manager and the other 16 sitting idle. The work will be distributed between them in a more "random" way. But it should be 50% overall.

Sorry for a silly question, just trying to rule out some possibilities - are you adjusting the correct number of threads? (there is one for production and one for IPR)

In my simple test the issue seems to be the same in Corona and V-Ray. If anyone has a V-Ray scene where this is clearly not happening, please contact us at https://support.chaos.com/hc/en-us/requests/new

Hi, sorry for the delay, your thread somehow wasn't marked as new for me.

If you are still getting this problem:
- Please let us know which exact version of Corona and 3ds Max you are using
- What is your CPU model?
- Is this happening only with batch rendering or also if you render from F9 / F10?
- In your screenshot, the rendering has actually started - it says "rendering initial pass" which basically means that Corona is rendering its first pass

If you have a scene where you can consistently reproduce this, please contact us at https://support.chaos.com/hc/en-us/requests/new and attach that scene.

Thanks in advance!

If render time is the priority for you, you might be able to get away with translucency only (no sss or volumetrics).

Some updates to the forum are planned, so we might consider a "forum chatbot" or a similar solution as well.

Perhaps you could try adjusting your settings to match a reference photo/render?

It's commonly reported by users and it seems to be a 3ds Max issue unrelated to Corona. The workaround I am using is selecting a material and pressing the A key to assign it.

[Max] Previews (Daily Builds) / Re: Fabric Material Playground!

« on: 2025-08-26, 18:31:03 »

Some more shenanigans. To get this effect, you first need to downscale your bitmap to the "resolution" of the fabric. For example, if you are using 100x100 wefts x warps, then your bitmap has to be 100x100px. It's best to use nearest neighbor filtering when downscaling. Additionally, once you load your bitmap as Corona Bitmap, set its filtering to nearest neighbor too. Optionally play with mapping to center your logo/texture and disable tiling. I also masked the logo with a procedural checker map to get interlacing.
