Hello!
I have a problem, (or babylon have a problem) with multiply transparency.
Look at this example scene in attachment
Just look around in this scene. Do you see how behave colored objects at different angles? They suddenly go out or become brighter.
Same problem in Unity discussed here: http://answers.unity3d.com/questions/609021/how-to-fix-transparent-rendering-problem.html
Waiting for Your solution...
Thank you!
