Steve:
When the alpha is somewhere between 0 and 1 you need to blend the color of the object with the background color. If alpha is 0.75 then the object image which has been pre-multiplied by alpha is at 75% brightness. When you multiply (1 - alpha) times the background color you get 25% of it's brightness. Adding the two together for the final image give a perfect blend. There is no resulting black fringe.
If there was any extra color from the Objects background (say a purple background) it would always bled into the final image even though there was no purple in either the object or the image that it's composited with.
thecolclough:
yeah, done a bit of reading and experimenting and i see where you're coming from now :)
kreator:
Build 1124 Keeps crashing when using UV tool whilst in subdivision mode. Just normal Jpeg images, also sometimes cannot exit faces that are yellow on occasion, if I save and exit then reload the texture has been applied
Steve:
Does this always happen, or is there a particular model/set of circumstances in which it occurs? I'm having trouble reproducing the crash.
kreator:
Just got 1127 version and am still getting crashes this happened just moving some points whilst editing a morph target.
