Hi,in my Generator object, I use textures/shaders for creating geometry. Since I use caching to speed up the performance, I do the following to check if anything in the object has changed, so the cache has to be recalculated:

Since, there is no PluginShader::CheckCache(), maybe this is possible using messages, but I don't know.
Any tipps? Thanks in advance! :-)
Cheers,
Jack

You can only check for container changes, IsDirty(DITY_DATA).
