[Max] Bug Reporting / Re: Corona 13 Color management problem

« on: 2024-08-23, 12:56:43 »

Fusion

To clarify:
saving from VFB works wrong for png and exr (and I guess other formats)
saving from renderoutput (native max) works for png and exr in 2024, but in 2025 it's working only for png, but not exr.

[Max] Bug Reporting / Corona 13 Color management problem

« on: 2024-08-23, 11:09:07 »

Hi, the image saved from a VFB looks different when color management is set to OCIO.

Display/View-Transform is enabled (obviously without it images are dark).

So, if max saves images or from native max VFB - all ok, but if I save it from VFB 2.0 or 1.0 - looks wrong. It seems like a few months ago all worked fine - I worked on a project in March and everything was fine (or I didn't notice the difference that time...)
The next one is probably max problem, but just to ask. Same settings:
2024 renderoutput - save png and exr exactly as in VFB.
2025 renderoutput - save png but not exr, exr is dark, it seems like it skips conversion.
Is it max problem or can be something you can fix?

Hi, looks like each time after installing a new version folder for out-of-core textures is reset to default, can you fix it?

[Max] Bug Reporting / single object multi/sub-obect absorpiton (refraction) problem

« on: 2024-02-19, 14:23:13 »

Hi,
looks like it's a very old problem but I thought it was fixed?

"liquid" inside "glass" works fine if it's 2 separate objects, but as soon as I attach them into a single - I'm getting result as on the screenshot.

Same materials, left side is separate objects, right side single object.
Top 4 - "liquid" without absorption
Bottom 4 - "glass" without absorption

[Max] Bug Reporting / Re: Corona Bitmap Color space/RGB primaries not working properly

yeah, I tried this as a workaround, but that's an additional step, especially when there are a lot of textures.

[Max] Bug Reporting / Corona Bitmap Color space/RGB primaries not working properly

« on: 2024-02-12, 13:53:04 »

Or maybe I'm doing something wrong?
Screenshot is attached

Changing RGB primaries in corona bitmap has a subtle, almost unnoticeable effect. 3dsmax bitmap working as expected by selecting color space during load (those settings not affecting corona bitmap).

Same thing here for a long time.

Haven't tried animation, but I noticed that different cameras for the same scene produce different shadows.

About "render has to be aborted..."
Clean scene - create some object, start interactive, create material, apply to object, load  bitmap, connect bitmap to some slot of material and you'll get an error. The are other scenarios as well. Not sure but seems like problem only wit max bitmap.

Hi,

With the latest DB I almost constantly get "Render had to be aborted because a bitmap on disk changed and is being reloaded. Continuing the render could cause crash or undefined behavior..." during IR.
Bitmap has not changed. It happens when I link bitmap to material or assigning material or just pick material from scene. Different scenes, different materials, different bitmaps.

Meantime, am I right in thinking that you can fix the actual production scene by replacing that material, and then attaching all the maps to the new Physical Material?

yep, correct.
Material without maps attached.

The scene itself is quite old, probably half a year (long playing project), but the material, as well as the pattern, was created after 3rd February, so it was created with the latest daily.
Just a couple of days ago and I already don't remember where it came from))) Not sure if I created it from scratch or imported it as legacy and then converted it to physical (and if so - how it was converted, manually or by the converter).

But the problem is definitely in the material: if I make a copy and apply it - the results are the same. So something inside that I can't see (or just not noticed) causes the problem.

You never know :)

Yeah))) Seems like the problem is solved by replacing the material of the patterned object.

The weird thing is in the attachments.
Material marked red - producing the wrong result.
Marked green seems to be correct.

While those materials look the same. I compared them step by step and didn't notice any differences. I tried to select the "default" preset for marked red - no changes.

Hi, here are fast interactive renders

First two - without corona pattern
Two next - copy of the same object with corona pattern mod.

The scene is quite big and complex but for previews I isolated just 4 objects. The reflective surface, sun + 2 objects to receive caustics (one with pattern)

Nothing to explain - seems like caustics don't see the pattern.

guys, but still, how about ignoring bump maps? V-Ray has this option

I'm sure this option will be very useful for creating more complex masks.
