Hello, I attempted to create a project in UE5.1.1 and used the TSS algorithm, so I created some passes and some shaders. At present, I am trying to use the NvFootprintFine function to obtain some expected data, but I have found that when I add this function to the shader, the following error will be reported. If I remove this function, the program can run normally. May I ask how I can solve this problem? Thank you very much for answering this question.
