directx-sdk-samples This version has cracks in mesh and texture distortion

The version in the DirectX 10 SDK is fine, but this update looks like it introduced issues.

Please be more specific about exactly which sample of the 40+ samples in the repo are showing an issue.

I assume this is a report of a problem with SubD11 that was also commented on the MSDN Code Gallery.

Yes, sorry I was not specific: SubD11 example

The problem is in the shader. It works if built with #43 (DXSDK) or #46 (VS 2012), but not with #47 (Windows 8.1 or Windows 10).

Do you mean there is a bug in the shader?

Apr 10 '16 16:04 RogersDoug

There's a bug in the shader compiler. Unfortunately it's a quite complex shader, so narrowing down the codegen bug and finding a workaround is difficult.

How about giving it to the compiler team to fix?

The FXC compiler is in 'sustaining' mode and has been for a long time, with all the focus of the HLSL team on the Shader Model 6 compiler (DXC) for DirectX 12.

With the most recent version (Windows 11), the problems around the lips are resolved but there are still a few incorrect triangle mappings visible on the face.
