Black model when inverting axis
#1
Hello,

I am transforming a ModelVisual3D using a matrix. If I try to invert an axis e.g. for x multiply the top row values with -1, all the Models3D turn black. There seems to be a problem with the lightning calculation I just don't know where.

Inverting the model normals kinda fixes the lightning but then naturally has the surfaces in the wrong direction.
The lightning is the ShowCameraLight from the TargetPositionCamera.

Any ideas how to fix it ?

Thank you
