Transparent mesh in render after using Voodoo/Blender camera tracker, any thoughts?

Lighting? Compositing fix? Losing my mind?

Blend file ? You may be losing your mind but we still can’t read it !

Thanks Richard, for your prompt response. I’ll repost this question when I’ve got my act together. The .blend file I tried to upload was clearly too large at 2.7 mb to do so. I’ll replicate the problem in a smaller file and take up space later. Thanks again.

washed.blend (1.18 MB)Any perspective on the attached would be much appreciated.

I see a monkey head on a cube which do render.
I see a movie clip in the video editor but this movie file is on the desktop of the computer in front of you, not in the blend file you posted so we can’t see it.
There is also a point cloud from voodoo. As these are just all single vertices with no faces between them they cannot be rendered unless you give them a halo material.
