Some pre-compiled shaders have trouble on Macs (MoltenVK translation) #76

Shaders are located @ engine/Xenko.Rendering/Rendering/Lights/LightPoint.xksl for example

The shader having trouble above is used in the "blank" template for the reflective, shiny sphere.

Newer MoltenVK libraries are available, worth trying to see if this helps (although haven't gotten the time to do so yet)

phr00t commented 3 years ago

I've updated MoltenVK libraries, but haven't checked this specifically yet.

There are other random errors relating to MoltenVK and latest Macs, so overall support for Macs has dropped due to these hoops to get Vulkan working on Macs.
