I am using 3Ds Max 2019 with the Arnold renderer
I am trying to render a moving object with a transparent background to overlay on a static background. Every time I try to render, the object has a white border around it. The only thing so far that's worked is to use black as the background (no environment map). This is problematic because it changes the lighting of the object and doesn't match the scene.
This is the scene :
This is the foreground, the blue background is just there to show white border
The alpha source of all bitmaps is set to "None (Opaque)"
Any help is greatly appreciated!
