Subject : How to share material between objects? (XSI->Mray)
Hi

I have 2000 grids with the same shader applied. (Every grid gets a deformation
with a plugin I have written, that's why I don't use instances)
The render tree is quite large (40-50 nodes).
If I try to render the scene, it takes 15 minutes (!) MRay starts. If I attach a
simple shader network, it takes 20 seconds to start the rendering...

I have checked an exported mi file. Every grid gets the whole render tree!
Does anybody know a workaround for my problem? How can I share a material
between multiple objects?


And I found out, that it takes lot more time if I connect one node to multiple
inputs of the next one. If I just connect the node to one input, it is much
faster...
