"stuck" material

[tycera]

What could cause a material being "stuck" to a system? I'm trying to apply a different material to a tyFlow but it's not being applied. Even if I apply it, close then open max again, still not updated.

Originally I was having trouble getting the Shell edge material IDs to render properly in VRay. I can't even troubleshoot it because of the above problem.

Edit: This is weird .... interactive rendering in the VRay Frame Buffer shows the correct material and material IDs. But render does not.

I'm not really sure what you mean, to be honest.

Are you sure you haven't (intentionally or accidentally) applied some instance materials to your particles (which override the material applied to the flow itself)?

Instance Material as in the operator? I haven't used any.
I have no idea why the VFB should show the correct material but the render won't. In the end I just applied a tyMesher and that enabled me to render it correctly.
