How to get good alpha blending?


Recommended Posts

Looks quite buggy, the 2 trees in the middle look wierd, since their upper part is sharp, and lower part is blurry. The upper part is against the skybox, and the lower part is against the terrain behind them.


Overall it looks rather like some broken DoF effect than antialiasing. The far away trees are clearly blurred by DoF, and also the away facing side of the closest tree on the left.

I think it looks good. They're using a forward renderer in that shot, which can be good in an outdoors scene with one directional light. However, it doesn't allow for shadow-casting point or spot lights.


With MSAA the edges of trees and small objects will look a lot smoother, pretty close to that image. MSAA will be added when the engine is updated to use OpenGL 3.

My job is to make tools you love, with the features you want, and performance you can't live without.
