Volumetric Light Not Matching in AE

[Brian Jones]

have to guess you are using a buffer which is cutting off the edge of the light as the buffer doesn’t extend past the geometry

Hi Brian,

Thanks for the insight. I didn’t know what a buffer is, but I looked into it and eventually waslead to fiddling with multi-pass settings, both in C4D render settings and in Cineware.

The change I made to fix the problem was in Cineware, checking the Cinema 4D Multi-Pass box, and then changing the multi-pass from RGBA Image to Atmosphere. But I don’t know what kind of effects this will have in future compositions, or why the RGBA Image didn’t work–if you have a moment to explain any of this, I would greatly appreciate it.

Thanks again!

Tom

alpha channels really, I guessed object buffer but that’s an alpha channel for just one object, useful with multipass rendering.
Multipass is the way to go if you are going to be compositing in AE (though I’m not an AE guy myself). The Volumetric light shows up in the Atmosphere channel so that’s why you were using it.
Without multipass the alpha channel you must have been using just took the geometry into account so the alpha cuts off the light, with multipass the alpha can apply only to the object layer and the light, on it’s own pass, doesn’t have to use the alpha channel and can be seen like in C4D

Thanks Brian! That’s super helpful 🙂
