alpha texture error
Need some help here! you can see from the screen shot that the alpha part of the plane is not entirely transparent. Cant figure this one out for the life of me. I have a gradient set up like I have in quite a few other pictures. I can even do the same type of thing in a new file and it works like a champ. its the settings somewhere in this picture…if anyone has any ideas please let me know!!!

Hey Jason
Did you ever figure this out. I’m coming up against the same problem in my file now.
Thanks

It has been quite awhile, but if I remember correctly it had to do with spacing on the gradient alpha channel. And I might be wrong but I never truly understood how I fixed it, but I did the same thing in the transparency channel and tweaked forever and somehow fixed it. To be dead honest I don’t know it really had to do with the material settings at all as I use alpha all the time and have never had the problem since.
On another note I suspect there might be an issue with how the materials that are set up with channels (i.e. luminescence, alpha, trans etc.) render over (at least to the camera viewpoint)other materials.
Otherwise I would have to revisit that set…let me know what you find! And sorry I couldn’t help more, its just been to long now. J

Hi Jason
Thanks for the quick response. You might be right about how the camera sees overlapping textures. I have some posters set over a wall texture and that may be the issue. I am also using a separate alpha file. I am going to try baking in the transparency to the poster RGB file. I doubt if that will make any difference but its worth trying.
Thanks again

Are you doing an animation or a still?

It’s just a still at this point. Was considering doing a little fly through just for fun. But at this stage I’ll just be happy to complete a render 🙂
I tried using a PSD with embedded transparency. Nope, no go. Played around with the layerset settings. Nothing changed. Going to try using PNGs next. I also read something about the surface normals being the wrong direction too. I doubt that is the cause but I will fool around with that too.
thanks

Normals wont make a difference if the material is both sides. And PNG wont make a difference either. Your better off with PSD. Often times its good know why something is doing the “thing” its doing, however, many times I run a second or more renders with alphas and object buffers and simply edit them in PS. The time you save is priceless! What is important is the end result. Don’t forget that PS can be just as powerful as Cinema.
Let me know what happens would ya?!
