Is there a sample of PT-SDK with blendshape animation?

the sample code shows how to integrate PT sdk with skeleton animation,
is there a sample showing PT sdk with blendshape animation?

Thank you for the question. There isn’t any support right now. But the main thing that the PT SDK is trying to demonstrate is that it does work with animated scene elements. The actual implementation of the animation isn’t important for demonstrating path tracing. There is nothing preventing blend shape animation being implemented in principle though.
