Point Look Up/Layer Mix in RS

Recommended Posts

Brand new to redshift and am trying to recreate something that seemed to only work in mantra.

Basically just want to take a heightfield and control the materials on the heightfield with a layer mix per each element (debris, bedrock, etc.) which was easy enough to do by binding in the attributes as the bias.

I've been looking around and it looks like instead of a bind you need to use a pointlookup and there are a few different substitutes for the layer mix in redshift it seems.

Simple sample file attached. Why doesn't it work?

Hi Andrew,

The problem was that you were using a Color Layer node instead of a Material Blend node.  Just change this and it'll work fine.  The Color Layer is for mixing colors and will only output color, and not the material attributes that you were expecting.

Also, I usually use the UserData nodes to read point attributes, not the ParticleAttributeLookup you had.  In Houini particles are points, but not sure if this workflow would work in Maya, so probably cleaner to use the UserData nodes in any case.

Hope this helps.
