My first pass code looks like:
XSI_RTS_ColorRGBA *color = in_pGeom->m_pColorPtrArray[0];
for(DWORD dwI = 0; dwI < in_pGeom->m_NbVertices; dwI++)
{
XSI_RTS_ColorRGBA a = *color;
color->m_alpha = 0;
color->m_blue = a.m_red;
color->m_green = a.m_green;
color->m_red = a.m_blue;
++color;
}
When applied to something simple like a cube it appears to work fine. When I
moved onto more complex meshes like a sphere it begins to go a bit wrong:
This is the view in shaded:

and the same view in dx:

Any clues you can give me about what I am doing wrong...
