white outline in image

[sfeely]

When I render out an animation with vray sun/sky, and save image sequence as tga's with alpha, I get a white outline around the buildings. The alpha does not remove it.

Any setting I'm forgetting?

Can you show an image?

I can take a guess and tell you that you need to render your objects against black background, to achieve proper alpha edging.

I once had the same problem and saved time by using 32bit TIF.

as Dmitry says, I guess you're saving premultiplied tgas against a gradient (the sky), instead of a black or any other solid colour.

If you have the Targa Image Control set to 32 Bits-Per-Pixel & check Pre-Multiplied Alpha on you should not have this issue
