Shadow from Ambient Occlusion on Transparency
show user profile  cartwright_mj
I have a quite complicated logo to go on a wall, too complicated to do as a mesh. If I make a plane and apply the logo as a jpg with a corresponding opacity map, it 'cuts out' great. However, when its next to a mesh with a ambient Occlusion ,material (the wall) the shadow of the whole plane shows. Any way around this?

in c4d you can change properties per object to allow certain colours/id's/opacity maps to only cast shadow and AO. im sure max did/does this

Cheers Guys. I found this over on 3dbuzz and it works great

"In the object properties set the G-Buffer Object ID to a non zero number. Then enter that number into the "AO material's Incl.Excl." with a negative sign in the front. This will exclude objects with that ID from that material's AO calculations"
