Hi all having some trouble with my scene and need some help with this because i have not got a clue on how to solve this.
The problem is this the scene is a bit heavy and i am having to render it out in several parts, but when i drag them into photoshop i get a white border around everything. ive looked online and some say to "Render against black background.check the premultiplied interpretation
and if you using Exposure Control Make sure you enable Process Background and Environment Maps"
Ok so i cant render against a black background. and i do have exposure control on and enable background environment maps.i am using iray and i dont think there is an option for premultiplied interpretation well none that i can find.
After reading bits on the online max help they say to save the file in a format that supports alpha channels.
ok so i tried that saved as a tiff and found the alpha channel in the channels bit in photoshop but then in photoshop i go to layers matting and to the options there and remove black and remove white does absolutely nothing.
Ive tried creating a selection from the alpha and deleting what i dont want from my picture but this method removes detail from the edges and looks terrible as you would expect, and this cant be how its done in the real world.
Ive also read that phtoshop dont do alphas properly and to use after effects well ive tried this and yes after effects recognizes the alpha and removes the background but again leaves a white line around everything no matter if i select straight or premultiplied matted with color in the interpret footage bit.
so any help that people can offer will be greatly appreciated.
Yes i am a simple noob so please use simple directions as i have not got a clue.
