Hi Gino, What form is your colour data? A Vec3Array? A Vec4Array? A Vec4ubArary?
With all of these the format will be RGB or RGBA so BGRA will not be appropriate. The code segments look like a hacks around drivers bugs to me as they don't seem related to what I'd expect the OSG to be passing. As a general comment I would strongly suggest you upgrade to the svn/trunk, OSG-3.0.0-rc1 as this will contain lots of bugs fixes and improvements over that was in 2.9.9. If it does come to applying a fix to the OSG it'll be svn/trunk or the OSG-3.0 so you usage of 2.9.9 just clouds the issue. Robert.
