I draw some polygon objects into viewport from ObjectData.Draw and have troubles with the overlapping of the objects. It seems that the objects are drawn from the foreground to the background of the scene, so the objects closer to the editorcam are overlapped by the objects with a larger distance. Ive tried to reverse the order of drawing, but it didnt fixed it. Flipping polygon normals didnt fixed it, too. Has anyone an idea?
Here 2 screenshots to illustrate the problem better.
Thx and Greetings

Hi Rownn, thanks for writing us.
With reference to your question, i wasn't able to reproduce the issue you mentioned. It's also unclear if the ObjectData is only responsible for drawing the polygon or also for generating some geometry in the scene. In my tests the polygon drawn by the ObjectData::Draw function appears properly represented in terms of draw-depth.
Might you provide some additional information?
I also suggest, although not 100% related, to have a look here where Frank (a former colleague of us) touched the draw topic concerning 2D primitives in TagData.

alot of thx for your efforts!
I´ve also wrote a special to test objectData and it produce the same issue.
from c4d import plugins, utils, bitmaps, gui
PLUGIN_ID = 1234589123 #TestID
class DrawTest(plugins.ObjectData) :
def GetVirtualObjects(self, op, hierarchyhelp) :
def Draw(self, op, drawpass, bd, bh) :
if drawpass!=c4d.DRAWPASS_HANDLES: return c4d.DRAWRESULT_SKIP
A = op.GetDown()
if not A: return c4d.DRAWRESULT_OK
B = A.GetNext()
if not B: return c4d.DRAWRESULT_OK
Ac = A.GetClone()
Ac[c4d.ID_BASEOBJECT_VISIBILITY_EDITOR] = 0
Bc = B.GetClone()
Bc[c4d.ID_BASEOBJECT_VISIBILITY_EDITOR] = 0
bd.DrawPolygonObject(bh, Ac, c4d.DRAWOBJECT_0)
bd.DrawPolygonObject(bh, Bc, c4d.DRAWOBJECT_0)
if __name__ == "__main__":
dir, file = os.path.split(__file__)
icon = bitmaps.BaseBitmap()
icon.InitWith(os.path.join(dir, "res", "Icon_Default.png"))

Make sure to reset the 3D matrix after you have draw everything in order to correctly set it back to 3D space as said in the article from Frank Willeke given by Riccardo

Unfortunately, it makes no difference. And in Py-RoundedTube.pyp this line is missed, too. But I´ll keep it in mind if I´ve to fix other issues.
