Bake to texture problems

[jens_mittendorf]

Hello,

I am trying to follow this tutorial https://docs.chaos.com/display/VMAX/...ing+with+V-Ray with no luck.

I just want to bake all the diffuse/ bump/ and Reflection maps from a very large multisub material and make them a one texture and one material with new UVs

1 - So if I want all the maps that are on the Diffuse slot to be baked into a new texture, without lighting information, just the original maps combined in a new texture, should I use the VRayDiffuseFilterMap or the VRayRawDiffuseFilterMap render element? and not the VRayCompleteMap?

2 - VRayRawReflectionFilterMap I do not get the same colors as the colors that are set on the reflection slot.

3 - Another problem that I have, evethough I set noise treshold to 0,01 and max subs to 24 to speed up rendering, when it reaches 0,01 noise treshold it continues rendering.. why is that?

thank you

HI, thanks for posting.
You have to setup a bake element for each render element that you need. If you need only the diffuse baked to texture then use the VRayDiffuseFilter. If you are not sure what to use when please refer to this page.
I don't fully understand your idea with the multi-sub material, could you share a bit more details about it (screengrabs).

What information do you get in the VRayLog? We might need a scene for this one.

[16:46:08.119] Noise threshold goal lowered to 0.142857

[16:46:24.492] Noise threshold goal lowered to 0.090909

[16:46:41.509] Noise threshold goal lowered to 0.052632

[16:46:58.903] Noise threshold goal set: 0.050000

...

[16:50:29.733] Progressive rendering finished: specified noise level reached

after 2 min rendering it reached the 0.05 treshold set in the render settings, but it keeps rendering 4 min more
When baking small textures this is no big deal, but when I go for the 8192x8192 textures at 0,03 noise treshold it adds too much time!!

Thank you

Hi,

after 2 min rendering it reached the 0.05 threshold set in the render settings, but it keeps rendering 4 min more

Could you send us this scene for a test? Please simplify it as much as you can while it still reproduces the issue and send it the support contact form for review.
