the (well known) custom backround issue

hello everyone !

I really like to use a good quality HDRI image to render my exterior images but sometimes the background doesn’t fit 100% with my project so

I tick the (sky/) ‘‘white background’’ and I use a nice image in photoshop (= HDRI is only used to light the scene - not visible !)

I render my image in 4K png + apply alpha channel…!

In photoshop, because of the white background I get the annoying white pixels around the geometry

that ruins all the quality of the image :

this in a well know issue in all render engines and I think is because of the anti-aliasing (and the big difference in brightness, I guess) !

but in corona render it can be easily eliminated when you render with black background !

Any ideas how this can be fixed in enscape ?

maybe instead of ‘‘white background’’ a ‘‘black backround’’ (or custom color) would be nice !

thanks in advance !

I think the way around this is to disable all the post processing effects, which don’t play so well with the alpha channel.

with :

Without:

Depth of field and wind intensity to 0 also might also have similar effects.

thank you Adam for your reply !

indeed , with 0 processing effects +0 dof +0 wind intensity, the result is much better !

not perfect … :slight_smile: but acceptable !

If I got that right,

Newest Release 3.4.1 will fix that problem …
