[Solved] Mesh decals clipping near camera

[CupMcCakers]

@Deathrey

You can project the UVs, You can encode all the data, needed to retrieve that, per vertex, during spline mesh creation. But it is prone to same limitations as before. If your render mesh is a flat splinemesh, at high angles/ lower camera height, you will inevitably run into a case, where UVs will be shifted beyond boundaries of the mesh or your camera would simply be below the mesh. In that case, you need a volume and task becomes exactly the same, as silhouette parallax occlusion mapping. You would need to split the mesh into prisms, with all the consequences of not being affordable real-time.

I think I’m halfway there, I’m making my spline conform to the landscape by using wpo and a heightmap. It’s not perfect, but it’s giving me acceptable results. I’m not sure how to go about encoding the data/retrieving it to project the uv’s, does that involve manipulating the world position (maybe rotating it) based off of the orientation of the decal in the world?
