Trying 1.8.3 here, with animation + layers.
My sequence is like this :
RGB_B0.#####.exr, going from RGB_B0.00051.exr to RGB_B0.00100.exr.
Adding path is a nightmare :
RGB_B0.00051.exr is changed to RGB_B0.%03d.exr ( should be RGB_B0.%05d.exr)
Adding other AOV path changed field from previous input Oo
So after adding all the path, RGB AOV path looks like :
Altus result seems awsome, but guys, I think it takes me more time to fight with the AltusGUI to encoded the path than computing the denoise.
