Exporting Holometrix

[John Cuevas]

I don’t have Holometrix, but in your render Output Module have you changed your Channels to “RGB + Alpha” and your format to something supports an alpha, like Quicktime Animation or PNG?

Thanks for responding. Yes, I’ve exported with an alpha channel. The area around the hologram is transparent. My issue is that I’m losing the semi transparency in the “hologram”.

Perhaps you have a mismatch in alpha intepretation? Have you exported premultiplied alpha when FCP is expecting straight?

See Alpha channel interpretation: premultiplied or straight (AE) [link] and Working with Clips That Have Alpha Channels (FCP) [link].

Thanks for the links. I’ll check them out. I actually exported both a straight and a matted (premultipled) version just to see if that was it. In both versions, the area around the “hologram” is transparent but the hologram has lost it’s semi transparency and is 100% opaque.

One thing I’m just now realizing In AE, when I turn off the visibility of the layer below the “hologram”, that’s when the hologram loses its semi transparency. Before it’s even rendered.
With mo layer below it, it’s 100% opaque. So it doesn’t seem to be a rendering issue. Again, I’m really new to AE and Holomatrix, but might holometrix be creating, or precomping, it’s semi transparency for the “hologram” based on the layer below?

Thanks again for your time and thoughts.

Has anyone viewing this post successfully rendered a holometrix layer by itself, with it’s partial opacity intact?
