Whenever I render out muzzle flashes (It’s just an mp4 file on a plane), it seems to render the color of the sky around it instead of the alpha channel. Please help me. The file uploader thingy wouldn’t work, so I made a mega link:https://mega.nz/#!VEsiSISb!M7ht6oObnFLW0l-hTUMlBaVJ4LgPjXqeLR3xAdYkskga
I don’t use the blender renderer so I can’t solve your problem but you should upload a simplified .blend along with any external data required to present the problem as I doubt many people would be willing to sort through the massive scene you have to figure out what is causing the problem.
