Colour issues...

Has anybody had any issues in regards to the colours going strange when looking in the DirectX Viewer?

For example I have a mesh with a mostly yellow texture on it, however in the viewer it turns blue, and other meshes go to other shades for no apparent reason.

I also have pivot issues (but it sounds like reseting XForm is the way to go about that one maybe)

Any thoughts on this would be appreciated. Thanks in advance.

Not generally. The things to watch out for are file format differences -- Windows is generally BGRA, Mac is generally RGBA. Also, vertex colors may come in a different order than you expect; if you're using a custom shader, try swizzing the color read instruction:

float4 myColor = vertexIn.bgra;

(This is the difference between D3DCOLOR and UBYTE4_NORM vertex formats)
