Dynamic blob shadow ?

If you know it is always going to be on a flat ground and you know the Z height you could simply use the vertex shader. Take your floor height and subtract WorldPosition.Z. Then multiply by 0,0,1 and hook to worldpositionoffset. Then add like 0,0,2 or something to keep it from zfighting.

Well, I assume that’s what big robot blob shadow does in Showdown VR demo, doesn’t it?

For bullettrain I solved it another way, using the vertex shader to shrink to the foot position and then re-expand along flattened local vectors.

Could you please post the material for such blob shadow? :o (assuming it’s mobile friendly)

To support slopes the easiest method is oversized geometry and using the worldposition behind translucency.

Well, as you can see my shadow plane is oversized, but it clips into the floor instead of render over it (as if it’s a decal). I still can’t find any examples or docs/tutorials about “worldposition behind translucency”. I’ll post my material setup after work and I wonder if you could modify it with “worldposition behind translucency” so I could have final piece of the puzzle with blob shadows solved and move on :o (and whoever else needs it would find an out-of-the-box solution useful). Could you please do that ?
