Re: Cached ice particle attribute in shader tree problem
hi, thanks for reply. i'v cached the attribute.
the problem is i use instance shape with shader that use ice attr. I found that if assign the material to point cloud, the instance shape work well in cache mode. If i assign material only to instance object , ice attribute can't be read.

Re: Cached ice particle attribute in shader tree problem
hi,
maybe i misunderstood but i think you need to force the evaluation of the attribute
read "beware ice optimization" here http://download.autodesk.com/global/doc ... 896F3-0020
in breif you can use this attribute in your ice tree, or displaying it when you are caching...
