Is it possible to make the viewer have transparent background?

You can change background color with scene.color but is there a way to remove the background color / make it transparent? I thought scene.alpha = true would do the job but it might be used for something else. I did a Hail Mary and changed the gl.clearColor alpha argument to 0 in the startFrame() function of scene.ts and it didn’t also work (still black).

So I was searching around for a solution to the general problem here - removing the background (whichever color) from an image that has alpha in it, and I happened on this stack question. I’ve tried the suggested “Greenfish Icon Editor Pro” just because it’s tiny and easier to get than GIMP/Photoshop/whatever big editor, and the results are actually good. For example, I did most of the testing with the water elemental, because that’s a fairly complex model when it comes to transparencies, and could never get to something remotely satisfying, while a simple button click got this:

So clearly the right solution here is not to enable alpha, but rather to either use an external tool that knows the proper cleaning algorithm, or implementing this algorithm in the code if automation is needed. I could ask someone I know who knows about image filters and manipulations, maybe they could help, but no promises.

This also means that I’ll probably remove ModelViewer.alpha and maybe also the WebGL parameters entirely, because it doesn’t really make sense for WC3 models.

I’ll close this for now. Maybe this experiment will help in some way in the future, who knows.
