Ok, I was convinced I had tried that last night but obviously I hadn't (was 2am
when I was trying it).
Anyway - here is my code now:
for(DWORD dwX = 0; dwX < in_pGeom->m_lNbColorStreams; dwX++)
{
for(DWORD dwI = 0; dwI < in_pGeom->m_NbVertices; dwI++)
{
color = in_pGeom->m_pColorPtrArray[dwI][dwX];
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;
in_pGeom->m_pColorPtrArray[dwI][dwX] = color;
}
}
and that works a hell of a lot better. I know that my mesh is a POSD with 1
colour stream. I seem to be getting rogue vertex colours though:

in_pGeom reports 144 vertices and they look like (before swizzle):
