I'm drawing a triangle with a color ramp in the Draw member of my ObjectData plugin using DrawPolygon.
It all shows fine if I have Enhanced OpenGL turned on.
If I have Enhanced OpenGL off, the triangle shows up black.
I'm drawing the triangle in the drawpass==c4d.DRAWPASS_OBJECT
Is there anything that I need to do to make it work with Enhanced OpenGL turned off?

Just found out that this only happens if my scene has any other polygonal object, besides my ObjectData object.
Would this help to spot the problem?

Also found out that is the additional polygonal object is in the scene but it is not visible, the triangle shows the color ramp, even without Enhanced OpenGL turned on.
As soon as a little bit of any polygonal object is shown in the editor, my DrawPolygon triangles appear black.

This is the default-code of the DrawHelper plugin and it works fine with OpenGL, Enhanced OGL and Software-Mode here on Windows 7 x64.
from c4d import Vector
def main() :
points = (
Vector(100, 0, 0),
Vector(0, 100, 0),
Vector(0, 0, 100),
colors = (
PS: Back then, I didn't knew about the use of the drawpass flag, so it's not in the code. But adding if drawpass != c4d.DRAWPASS_OBJECT: return works fine, too.

My code was similar to that one, Niklas.
Try using it with a polygonal object added to the scene to see if it is drawn black.
But, in the meanwhile, I found out the solution.
I just had to add the following before drawing the polygon:
