I have this problem as you can see, but only when i drop the plane to the ground. Nothing helps with adjusting the shadows. The alpha is built into the tga file.

And this is the issue.

This seems like a similar problem (or at least the same root cause) as the one Tubbritt had in the thread above.

Hm, strange...no, niothing there helps I will just have to keep it off the ground i suppose. I do think it is odd though. Almost like AO is causing it as it does with certain lighting in Cinema 4D (;

Yes, keeping the alphaplanes slightly away from the surface underneath was the solution that worked with Tubbritt.

Yeah sorry, your right. I was reading all the translucence and such as well got confused :D

For this problem however it will have to be "faked" in photoshop as an afterthought to achieve the effect i want. I have never seen this behavior in Vue and have been using 6Infinite since its birth.  I am assuming e-on knows already.

I had this problem too, and Tech support told me there was nothing to do about it atm, it's a limitation of the Vue renderer. Any object that uses a transmap when in contact with another surface will create this artefact. The only thing you can do is lift up the alpha plane like +0.01 cm, this should do the trick and may not be noticeable, depending on the camera angle. Might screw up the sahdows though.

Right, exactly bruno, it isnt a physical object (could model one if i had to i guess) so i would like it to be able to cast shadows, and i was going to have steam coming from the "holes" in the top so i wanted it to be relative close up. I think i will just have to model it the more i think about it as i type this actually. Then i can just cubemap the alpha onto the disk and see where that gets me.

What makes me wonder though is if you look at the bottom pic you can see around the edge of the cover it looks like it wants to work then just decides not to. You can see the ground through the alpha around the edge.
