Corona Multimap help

Corona Corona for 3ds Max Help Required

Struggling to get the results I want with Multimap in diffuse. I’ve created a clump of grass and am trying to get each blade to be a slightly different shade.

When I set the Multimap to Instance it sets the colour of the clumps as a whole. When I set it to Primitive it seems to affect the individual poly or triangle.

Is it possible to have each blade a random different shade of green. I guess I could use material ID but then the colours would match for each clump I think.

Any suggestions?

Edit

From a performance point of view when making grass is it better to scatter a clump or individual blades?

From what I know, not possible yet. It would require per element distribution, or something similar.

Clump. Especially if you are rendering a massive lawn. :smiley:

Another idea. Nested multi maps. :smiley: This makes few variations of the clump. The pattern should not be very obvious and it will be totally unnoticeable if you add random z rotation.

Interesting. Thanks for your help. Currently I’ve gone for various clumps with different material ID’s but your way might offer better performance.
