When you change diag_drawMode , you can't tell the "boundary" between different surfaces of an object, because there's no shading. The object is just a white blob.
Without any shading it's impossible to look at building interiors. Once you enter the building everything is white...
Please add a simple shading (such as Phong) to the surfaces.
There is a wireframe mode, "Wire".
We should just force enable that with all the other diag modes (except normal), that should be sufficient.
Actually. I think you can already do that, I think its seperate from the others
calling diag_drawMode "Wire" should switch between wireframe modes
Modes: "None", "Wireframe", "WireframeOnSolid"
Okey yeah no. half of that code is enabled in diag builds, other half is not.. but you need both halves :D Seems like someone intended to enable this, but stopped half way through
Wire mode is fixed next dev branch, it can be combined with others.
You won't get phong shader
