I’m trying to replace the Flare constants with variables to use in a control rig. When I try to follow the instructions from unreal (Creating Deformers in Unreal 5.5 | Talks and demos), I get a bunch of errors. Some are saying no ; on several declarations, and others are not recognizing the DebugDraw declaration or what appear to be standard functions, like MatrixInvers_Affine. I tried rebuilding the shader outside of the source flare deformer, and got the same errors. I’m guessing it needs some programming environments installed on my machine to work properly, but that’s a bit of a bug if these are meant to be accessible to artists using the engine. Here are the errors from the flare recompile when I replace the constants with variables. The following image is what I get when I try to compile in my own deformer graph, but also after I removed the debug functions. From some web searches I think the undeclared functions are supposed to be common shader functions that a compiler should recognize.
Is there anything I’m missing that I can do to fix these issues?
