Video on opacity channel

The opacity channel of the materials, does not accept maps?
It would be interesting if it accepts opacity maps in image and video format. This is possible?
Thank you so much

Yes, the opacity channel does not accept maps. However, alpha channel opacity is supported for base color textures.

As for the video, something we’d like to add at some point is support for “green screen” transparency, that is treating a specific color of the video as transparent.

Thank you!
That would surely be a great implementation.
So would a grayscale video alpha map.
