Any help debugging maerials I am getting an error here with a flaot3 to float4 cast. But mat_params doesnt have a V4 only v3 parameters. Any help on how I might find the error and correct it or what the error might be indicating is appreciated.

Its something inside function “mat_params”.
Maybe one of inputs are V4, not V3?

Thanks! Basically the V3 Input was later being used as a V4 in a node within the mata_params functions. I guess it treats the Material as the root and all problems show up there may be within any of the functions. Is there a way to get more information for an error?
