random color shift in precomp?
I’ve got a precomp with some jpgs from a client in them. They’re 3d layers, and the precomp is set to infinite raster in my Main comp that I’ll render from
I was having a weird issue where the blacks in my renders would be significantly different. Actually there was a large color shift. Everything was fine in AE and Color Finesse, but the renders – no matter the codec – all were slightly magenta.
I did some render tests from directly inside the precomp and everything was fine. It was something to do with the infinite rasterization that was causing the renders to be different
Any thoughts??
RGB image files (PSD files). Normal blend modes on all layers, minimal color effects on any layers, no adjustment layers, no lights… Everything was fine in AE until render time.
Any one else experienced anything like this?

Nope, nothing to do with Open GL. I rarely ever even use it

Could this be the result of lighting and material settings? Lights within that precomp will be ignored. Lights within the main comp will be applied.

CS5, yes
No footage – just PSD layers (RGB)
And no lights at all
I’m attaching a jpg (I think)
on the Right is how it looks in AE. On the left is how it’s rendering (again – ANY codec, more or less looks like this)
If I rendered directly from the precomp, it looks like it does on the right. It’s when the precomp has inf. raster turned on that it looks WRONG

Very strange! Do you see the shift in RAM preview as well as render? Are you using color management? Do the colors render correctly without Collapse Transformations on? Are there any effects applied to the precomp itself in the main comp? Perhaps a shy adjustment layer?

TOTALLY strange
-No shift when RAM preview…-Color management is None (though I did play around with it a bit with no positive effect)
-Colors render correctly when collapse transformations is OFF, but NOT if they are on.
-no effects applied to the precomp. No adjustment layers
I haven’t experimented with any other image files, so I suppose there’s something about that particular Photoshop file (though I don’t know what – no effects on those layers in PS, either). Or maybe it’s just a fluke.
I guess I’d be less nervous if other people were having this issue as well

What bit depth are you working at? Have you tried rendering to a PSD sequence?

– Tried 8 and 16 bit
– and yup, rendered out tif and tga sequences (didn’t do PSD specifically)

Sorry, Joel — I’m not really sure what else to suggest (other than perhaps filing a bug report [link] if the problem is reproducible). Can you post a reduced project that shows the problem?
