I’m trying to add caustic reflections on my walls but can not find a way to do it in HDRP. I know how to do it with a shader that affects an entire surface (such as for underwater caustics) but I need a way to add them in a local space.
Here’s an example of what I’m trying to do:
That’s using a decal projector but (afaik) the HDRP/Decal shader does not support animation or layering multiple images.
So I tried creating a custom Decal Shader Graph but for some strange reason I can’t figure out how to get transparency to work?? Which is odd considering you’d think that’s the one thing 95% of decals need.
Here is what I mean:
Is there any way to achieve what I want using the Decal Master node? Or even a tutorial on how to use it (that I’ve somehow missed)?
Or am I overthinking this? Is there an easier way to add fake caustics that I’m overlooking?
