Thanks Jooja for the quick response.
We use maya for animation and are not that familiar with MR rendering.
I followed your guidance as good as I could but can't get the correct result...
Couldn't find any 'list of raytracable objects'. After searching inet this is what I came up with:
I set the color of the cylinder's lambert to red.
I wasn't sure for this one so I tried 2 things Setting the mib_Reflects color and setting the camera's environment (I set this to green for testing purposes)...
and/or...
And finally...
Unfortunatly I got the wrong result...
The color is green as set in the camera's environment bot no red dot... ???
Any suggestions?
