render layers refraction
...you'd think i'd have render layers mastered by now...
but anyway, i have a transparent bubble and when i use render layers the stuff behind it doesn't show up in the diffuse pass, and i have a refraction pass which shows all the refractions and everything behind the objects with transparency so the question is, if i have a layer with all the refractions and the alpha channel covers everything then how do i composite it onto the diffuse? |
i don't really know what you mean by refraction pass tbh, but you could switch the alpha channel with which ever one you want. just do a quick ID pass.
what are you using to composite? |
by refraction pass i mean a layer that just has what you get from the refractions on it
(it seems necessary since the diffuse pass just rendered the transparent object as white which i suppose is what we'd expect?) i was trying it with photoshop first, but it's an image sequence so i'd be compositing it in AE or FCP |
hey man, post up a screenshot.
I'm not sure you need a refractions pass. you could just add it into your beauty pass. you could maybe just do a reflections and a specular and a beauty. i've never made a bubble tho... |
will post when i get home
|
eeh, i don't think there's any point in posting the images
well.... one i'm too lazy, and two, none of the passes have an alpha channels other than the master beauty :confused: maybe i did something wrong with the rendering, the command line did throw a lot of warnings when it went to render stuff... |
well here are some that i did after your posting :D
the render layer were just a series of reflections http://i7.photobucket.com/albums/y29...g?t=1241040424 it didn't take long which is why they are not great |
I'm confused on it too tbh. A reflection pass on every surface should get the same results (or as least as far as every render I've done it does)
|
reflection gives the same results as refraction?
uh, i think you just lost me :confused: |
