Broken shaders when exporting from Anima to Vrayscene

[justini]

When can we expect this bug fix to be released?

From the AXYZ website:
"The VrScenes exported from anima® have an issue with their textures in the latest V-ray versions. ChaosGroup® has confirmed to us that they have already made a bugfix for this problem and it will be included in their next releases of both V-ray Next® and V-ray 5®"

If you are referring to the note from this release - https://secure.axyz-design.com/en/bl...r-4-0-3-update, the fix is already in 5 and Next.

Can you please describe the issue you are having and with what Anima version? There are known issues with the latest 4D people - https://docs.chaosgroup.com/display/...tedFeatures-11

[justini]

I think the guys are using version 4.03 of Anima. I can confirm tomorrow but I know they are not using 4.5.

The people in the attached render named "vrayscene.jpg" have incorrect specularity, making everything look like plastic or leather.
The people in "Anima_import.jpg" are imported with the help of the Anima plugin directly in 3ds max.

Are there any plans to introduce the ability to adjust materials within a vrayscene file?

[justini]

Yes. We are on version 4.03 of Anima.

Not for now.

For the shader issue - can you please isolate a geometry with a problematic material and send it over?

Sure here is the link. It has just the vrayscene file with a light and camera. Texture maps are supplied too.

For comparison i've attached a quick render comparing the vrayscene materials with the ones imported through the anima plugin.

It doesn't look like just incorrect gamma values. Seems like something entirely different going on.

Can you please upload the max archive as well?

Mh, that looks precisely like maps are coming in with a double amount of Gamma applied.
As the shader effects are all driven by maps, it stands to reason they ought to do "more" (of reflection, spec, and so on) as they are "whiter".

I tried but the archive operation kept failing

was there any resolution to this issue...? I am about to start a large project and was planning on using anima / chaos cloud. This could be a deal breaker!

Reading through the vrscene file, *all* bitmaps are exported with gamma 1.0, which would explain your renders' looks.
You could probably run a search and replace for "gamma=1.0" (*not* "gamma=1", that's apparently hardcoded for normal maps.) to "gamma=0.4545", in any text editor, and you may get away with it.
I've attached you a modified vrscene file for you to test (we can't as you never sent us the data to do so.).

So the only solution if rendering with anima 4 via chaos cloud is to export the scene to vrscene, then manually edit, then upload to chaos cloud. I would assume rendering to another 3rd party render service would be moot as you cant generally just upload a vrscene to Rebus for example.
That's annoying.....I appreciate it's probably not a high priority but will there likely be any progress on dealing with this anytime soon , is it primarily an issue for the AXYZ developers to address or a Chaos issue?

It's for whoever writes the vrscene, i'd assume.
If Anima exports directly, then it's for them to fix.
