With shaders it’s more tedious, as you might have to dig deep into the Explorer to find the shader. The method I described with editing the spdl is probably faster than the SDK Explorer with shaders.

I’m not sure what you mean by “simplest way to prevent….”

I don’t know any simple of doing what you’re after. This is what I refer to in “”Getting the “root” shader from a shader”". It’s super easy to walk down the render tree (going from output to inputs, or from root to branches) but it’s hard to walk up (from branches to root). I’ve never found a SDK entry that discusses output-input relationship between shaders.

My best advice, unfortunately, would be to either loop the shaders after a FindShaders(), or recursively traverse the render tree, until you find parameters that have a cell shader connected into them.
