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:

Is it possible to trace changes in a shader/texture (class PluginShader)? Of course, when the shader changes, my object must also 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).
