How to avoid white border in Corona Renderer?

(1/2) > >>

Schlee:
Hi all

I do get at Corona Renderer when using alpha channel (PNG) a white border after rendering.

I did watch some videos which mentioned in the render setting to select "direct visibility override".... but it doesn't help.

Any ideas?

Many thanks

Mike

If this static, then Photoshop has this technique:
Ctrl+click by layer > Invert selection - Ctrl+Shift+I > press 2-3 times Del.

Straight Alpha... ?

Hi and Thanks

@aler, this is a solution, but it looks after that it looks very pixelated.

@burnin, I have selected "Straight Alpha" in the render setting now, but I still see the white border. Do I have to consider something else?

Is there not a out of the box solution for this problem in Corona renderer?

many thanks

Mike

It's not a corona thing, its a C4D thing, saving out transparent PNGs out of the picture viewer is a very hit and miss thing. Just add the alpha as a render layer and then make it transparent in post.
