I’ve been using Alpha Composite materials in my vfx for a while now, but I’ve had trouble finding much documentation on how this blend mode works, how to author for it, and the advantages of it over additive or translucency. So I decided to write a small document going over what I’ve learned, as well as a few other resources I’ve found on how to use this blend mode.
I haven’t seen much comprehensive documentation on this, so I hope this is helpful.
Feedback and suggestions are welcome! If anyone has any information I don’t cover or anything is incorrect I would be happy to add or revise the documents
