Animation Project: Woops

In some of the scenes I did, I couldn't put the background into maya as it would not light properly

At the time I was exporting as PNG sequences, due to a mistake in my mind being  twat, I didn't export the EXR properly the first time and thought it was the exr format that didn't work, not realizing my mistake.

Before that I messed around in after effects seeing if I could get the black background out my masking the animation layer however the lighting in the animation is quite dark and left the image transparent.

 

eexr, didn't work the first time, not because I thought it was the wrong file type but because in the render settings I didn't have it exporting in a way that the exr file could be used but after fixing that the scene rendered without the black background just fine
