Hi,

I have created a scene with point particles (instanced with geometry) and I hardware render them with full image resolution, as tiff, and tried targa, alpha off, etc. The particles show up very nicely but then when I composite the sequence in my scene, with a blue background, the particle seq comes in with a black bg. I thought it would be trasparent.

I have a pic of what it looks like but I had to convert it from tif to jpg to post here.



The background option is set to black. I dont know what else to do.....Any suggestions?
