Problem with Maya when baking out UDIMs

[deckel]

Hello everyone,

i have a problem when baking out textures with UDIM.
This is the first time i use this so maybe i`am doing something wrong.
Here are the single steps i did.

-1: Create a plain, assign a vRayMtl with a volume noise.
-2: Create UVs like in the attechement.
-3: Assign single vRay Bake Option and check "Bake UDIM " option.
-4: Create a Diffuse render element.

Now when I hit "Bake with vRay", the outcoming textures are complete empty.
Do I something wrong?
Plese help me.

There is something wrong in this case indeed and I'm looking into it now. I have a temporary fix, but I need to look into the problem a bit further.

Best regards,

OK, cool. Thank you.
Do you actually sleep sometimes?

Do you actually sleep sometimes?

Surpisingly, yes Anyways, I do have a fix for you now - do you have access to the nightly builds?

Best regards,
Vlado

[Hase]

yes, i do have access to nightly builds

[vlado]

Ok, great. The latest 3.57 build should work fine with that scene.

Best regards,
Vlado

Cool,
I try it out as soon as possible.
Thank you Vlado.

Hi,

I've been having a similar issue. Maybe something related? Using (V-Ray core version is 3.25.01, V-Ray Standalone, version 3.57.01 for x64, Build 27353 from Apr 18 2017)

Whenever I try to bake UDIMs the render starts and does the first one, but then stops. It outputs images for all udims, but they are all have the same image inside (UDIM 1001). I select UDIM Baking and Clamp UDIM region (to the UDIM range say 1001 to 1003). I tried changing settings and playing around with the vrayBakeOptions on the object, with a fresh scene with a cube, but still have the same issue,

Any help would be great,

Thanks!

Some logs that might help pointing out the issue:

This is the log of the maya script editor:

Sorry for the multiple posts but there's a characters limit to the replies,

And this is the log of vray (as you can see it does not render the second frame but saves it anyway):

Thanks again for the help,

That's a bug that should already be fixed. You can try with the latest available 3.5 stable nightly (build 27491 from 22 June). The 3.6 stable nightlies should also work fine.
Could you give it a try with a newer build and let us know if it works correctly, please?

[pizzaia]

Thank you for the reply, will try with the nightly version.
