I feel really stupid asking this, but I can't seem to find any way to figure this out.
I was having issues with my render pass in Vulkan and eventually tracked it to the winding (clockwise vs counterclockwise).
After having slapped my forehead far too hard, I then tried to figure out what the windings of the triangles were in the RenderDoc MeshViewer so that I wouldn't screw this up again.
This is such a fundamental thing that I'm clearly missing the obvious. I have Googled and searched the docs, but the only thing I found was something on the programmatic interface, and nothing in the GUI itself.
Thanks for the help.
It's in PipelineState->Rasterizer->RasterizerState->Front CCW.
