Help: vray (and xmesh?) splotches in render


#1

Hi guys,
the trouble of the day is: splotches on animated (baked) geometry in a prepass mode render.

Infact:

  • if I render in prepass mode (blending GI solutions per frame) artifacts appear on the mesh and a high setting is needed for an attenuation of them;
  • if I render in single frame mode I obtain fine results.

My questions:
-Now, my baked walking character is an xmesh geometry, can its trimesh be a problem for vray (for smoothing surely :slight_smile: )?
-Why single frame mode is cleaner then prepass mode?


#2

Try setting some interpolation mode in xmesh loader.
If vray samples across time that may help.

tnx for reply,
Tried all loading mode types…trouble persists :frowning:
Other advice?
I continue to try other solutions

Sorry, I haven’t got an XMesh license anymore or I would try and help. :frowning:

I would post to Thinkbox. :wink:

Hey Johnny,
I have only the free loader and the baked sequences…here.
Trying on mesher copies and other stuff, problems add to problems…single frame renders fly like a charm (fortunately).
Chaos and ThinkB are the next step if the problem isn’t my workflow :slight_smile:

Hey Savat, sorry for late reply, IIRC I believe you need to include textureCoords and/or smoothingGroups in your export.


#7

…seems that my model have only ID channel saved on it but smoothing and other info are added by modifiers.
I will procure a xmesh with smoothing channel too for a new test.
At the moment, I’ve solved simply not using the vray “prepass” mode.

Thanks for your input :slight_smile:
