When using non-8bit images as textures or image planes in 3D, only the bottom portion of the image is drawn. This can also occur when selecting a Tracker pattern.

The lack of image problem is an NVidia driver bug. For 3D views, images are always uploaded to 8bit textures. So when the image isn't 8bit it must converted and that exhibits the driver conversion issue.

You can temporarily set the image to 8bit using a Change Depth tool, and disable it before final render.

The error has been reported to NVidia, and appears to be fixed as of revision 162.18 and later.

New for Fusion 5.2: Setting the environment variable FUSION_TEXTURE_CONVERT to true will cause Fusion to do the texture conversions itself, bypassing this driver bug.
