  1. Sticky Arnold Triplanar Texture

    Hey guys and gals. Im playing with something in Arnold for Houdini. I created a cube and shattered it in quick falling down sim. Created rest position before assemble and simulation. After sim I do unpack (all attributes preserved) attach shader (just standard with checkerboard) to see how triplanar shader works with animated geometry. It works as expected for the first part. Renders trough all the pieces all nice. But obviously when pieces start moving (falling) they slide trough triplanar projection. Now, there is this coord space option that says Pref and according to the docs is a vertex in reference pose, great I was thinking that is it. But still pieces slide trough triplanar texture. I tried copying and renaming rest attribute (created after voronoi on first frame) from points to primitives and even renaming to pref...but it’s not working. Was anyone able to create sticky triplanar texture in htoa? Thanks a bunch!
  2. So I used the Triplanar Projection vop to give some geometry a diffuse texture. It was really easy, and I am happy with the results. However, now I want to add displacement to the same object with a displacement map which matches my diffuse texture. Since the triplanar projection vop only outputs color, how can I supply my shader the outN and doffset values that the Displace Texture vop supplies?
