Hey!
There is a "shadow" in the diffuse matte alpha. The alpha of the teapot should be 100% black.
Look at the screenshot please.

+1 Remove or make static noise optional. I've bought octane for animation purpose - static noise is a NOGO

I had a shadow in my matte-alphas too. After disabling every scene light I could generate the correct alphas. I think it's a bug...

My first Post. Yay.

On 24 fps

180° = 1/48 frame duration, 360° = 1/24 frame duration
