Corona render, material can't be assigned

[clasyc]

Hey...as it says there in the "info" box of the material operator, it only has effect on VRay instances.

If you want to assign a material to your particles, apply it to the tyFlow object itself. If you need multiple materials, use a mutli/sub material and assign material IDs to your particles.

Ye.., I've seen the info box, but made some incorrect assumptions. Sorry
