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.

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