Looking good!

I would rename defaultMode to enabled. And... how's monochrome related to this feature?

monochromatic was just left there from debugging, to see the effect different. I was thinking of adding a more complex mesh (i struggled with transparency on mechanical parts, like plates with holes) but is it needed? Ie. any other thoughts? Some comments in the code or a description on the page might also be useful.

Actually it's fairly self explanatory. All i can think of from my naive approach is trying to write to the main buffer instead of an off screen one. I'll remove the [wip].

This one's really messy but it does it with less buffers, and stencil i hope might speed things up a bit. I'm struggling getting the same blending though:

Any concerns on landing this?

I'm following this too. Where is the best place to get the most up-to-date code right now, so I can try and see if I can make my own implementation?

Most up to date code for what?

Most up to date code for what?

Your example. Should I just rip the files from the githack?

Ah yes. It’s all contained within that example file. Unfortunately the other approach doesn’t work, because threejs locks the render buffers to render targets :(

So the second link won’t work for you unless you also use the build from that branch. The first one will but it’s not very fast.

Closing in favor of #24903.

This one has significantly better visual results than #24903 depending on the use case. It would be nice if multiple OIT methods could be accepted, with differing API names, rather than only a single one.

Having this as just an example would be great, until someone else can take it further to integrate it as a feature in a renderer and/or material.
