Hey guys, So I am having a problem with getting an alpha channel on a texture that is camera projected inside of Arnold. I can get the image to have transparency with a regular texture along the railing....but I cant duplicate that process for when I need to camera map onto the geometry in the background. The plane on the left with the green behind it is just showing that there is transparency along the top of the photo, and that the alpha channel is working. But above the green texture, that same railing does not have transparency, when the texture needs to be camera projected. Any advise? https://www.dropbox.com/s/8b419a5wog90s9k/Projection_Mapping_Alpha_Issue.jpg?dl=0
OK! Hey fellas... I modeled a dice...using a cube, and a bunch of sphere's...all placed disecting the geometry in the cube in their proper positions. Placed EVERYTHING into a Bool A-B...and as long as I have a solid material on the cube...I have my dice! the problem arises when I try and put a red transparent material onto the cube (ya know...like a REAL casino dice) i can see the cut outs of the other sphere's clear through the die... I know if it's transparent... I SHOULD be able to see the divits on the other sides...but this doesn't look quite right. If anyone has any lighting/compositing/material advice...I would greatly appreciate it. And since I'm a newbie...if anyone wants to let me know how to post some screen shots, I would be more than happy to do so just so you guys (and gals) could see how I have things set up. Merry Christmas! Greg http://Rescueskier1970.imgur.com/all/
