Thank you for the report! Sorry for the delayed response!
Are you able to compile a simpler deformer graph? Or a deformer graph available under the “Deformers” folder in the Deformer Graph plugin such as the DG_LinearBlendSkin?
It would help me identify the issue if you can provide a screenshot of the entire graph you are compiling, the shader code for your custom kernel if you can share, as well as a screenshot of the details panel when you have the compute kernel selected.
Functions like MatrixInverse_Affine are declared in a DeformerSourceLibrary asset called DSL_Matrix from the DeformerGraph plugin, you will need to manually add this asset to the “Additional Sources” property of your custom compute kernel.
Thanks,
Jack
