Trying to get the Material for a PluginShader from within ShaderData.Init() (my own shader plugin). The code below always returns h == NULL and returns FALSE. The PluginShader GeListNode has no GeListHead? If I'm trying too early, where else, praytell, would I be able to do this?

  
     PluginShader *ps = (PluginShader* )node;  
     // Get Shader's Material (hack)  
     GeListHead* h;  
     if (!(h = ps->GetListHead())) { GePrint("iShader.Init.h"); return FALSE; }  
     material = static_cast<Material*>(h->GetParent());  
     if (!material || (material->GetType() != Mmaterial)) { GePrint("iShader.Init.material"); return FALSE; }

Well, I found a hack of my own.

There is only one message sent to the ShaderPlugin (into ShaderData) that isn't repeated twenty times - gad, you guys need to fix this (if you haven't in later SDK versions) - MSG_DESCTIPTION_INITUNDO. This allows me to grab the material (as above - yes, it works there, but not in ShaderData.Init()) and do my thing.
