3ds max exporting to after effects with transparent background
show user profile  jamieslimmon

Does anyone know the best practice for exporting animation (with a transparent background) from max to after effects – so that you don’t get an annoying halo/matte fringe around the edges? I’ve done so much research, I know longer know where to look. I’ve tried exporting pngs/tga/tiffs/.movs. There’s probably an incredibly simple answer to this question… but it’s taking me literally days to search for this – and I’m still no closer. Any help would greatly appreciated…

Not really familiar with AE much, but if I remember correctly from the times I played with it, it was similar to photoshop in ways, and photoshop deals with the halos with the layer > matting > remove black/white matte tool.

So you just export with alpha (premultiplied was the one I remember) to an image format, import to AE and run the matting tool.

Thanks very much for your fast reply - it's a fantastic suggestion but unfortunately I've tried that one already... it partially worked (got rid of the black halo) but further along in the animation it developed a white halo. Totally flumoxed

Export as TGA's with alpha.... (any format WITH alpha).

Import into AE.....when importing you will have the option to choose for "type" of alpha in the interpret footage dialog box. Choose "premultiplied"........if you arent sure how you exported from MAX and premultiplied doesnt work quite right.......then higlight the footage in the Project window, right click-> "interpret footage"...then try "straight" alpha.

Thanks Dr Jim,

But I've tried that also. but unfortunately it doesn't work on my anim - it's driving me totally bonkers. I'm rendering out out on a pure black background in max...

to avoid faffing export from MAX as Straight alpha.

TARGA files 32bit (untick the pre-multiplied alpha)
