I do like this:
1. I import one object modeled with houdini to mari and paint ptex texture.
2.then import the object from mari to houdini.
but ,I found that the textures on models built with quad faces is OK,but for trigle and pentagon ,the textures is incorrect.
then i downloaded the samples from ptex website and import them to houdini ,the same problem is again.
so ,how to fix the problem?
thanks
samples:
ptex.us/samples/triangle.zip
ptex.us/samples/pentagon.zip

Technical Discussion » How to output the object ID to deep raster planes?
- flyingc
- 160 posts
- Offline
the below word is form help document.
:
Tip
You can output the object ID and/or primitive IDs to deep raster planes, and then use them to easily select objects or primitives in the compositor.
To output the object or primitive ID, set up the following parameters:
* Variable name = Op_Id (or Prim_Id)
* File/Plane name = Op_Id (or Prim_Id)
* Channel depth, Variable type = Floating point
* Sample filter = closest surface
* Pixel filter = minmax idcover (a special filtering mode for ID channels)
the question is :
how and where to set up this parameters?
thanks

SoothsayerYes.i think so.
Hm. Isn't that setting used to decouple shadows steps when using volumes?
Pure Dumb Luck..so i feel it is very puzzled

there is no depth of field
the attachment is scene file.
but the thing changed very strange.
i add the parameter shown in the picture below for the light named top ,then the stains were disappear .but if delete this parameter , the error is no longer appear
but I don't know what is use of the parameter.

hi
i want to render diffuse passes for each light,so I add extra image plane in mantra and use this setting.
but the rendered image is very funny~
how to deal with it?
