I downloaded the model importer patch and ran it in QC. It works fine. I then made a quick model in Blender, exported as DAE, and routed that through the patch. All I got was a blank screen. The Blender file was just the basic light, camera, object with a quick deform done to it.
I tried several methods including drag drop the file, duplicate the input splitter and enter the file path, and only got the black screen.
Is the deform a nurbs deform,or a vertex deform? Can you bake the deform in, or, if its an animation, ensure its a skinned animation and not a per vertex / frame animation (ie, the model has bones, joints, joint weights and animates by moving the joints, rather than swapping out sets of geometry?)
Also, try removing the light and the camera? I dont know blender at all, so im unsure how I can help, but post the file too, maybe?
