Although I should reiterate that I usually use it on the entire frame. I'm making a sometimes-2d sometimes 3d game and it would be available there.

I've tried everything. Test it out as an actual UI and let me know, please.

Egon, have you ever run into the problem with AWTGLCanvas in which the entire rendering is out of place on the canvas that I did about a decade ago and ever since on every computer I've ever run my stuff on? I'd love to have that fixed (most likely by switching to lwjgl 3 and convincing them to add AWTGLCanvas back). What do you think?

To elaborate, I get a List<Channel> for the entire animation set from my importer. But without knowing what's what, I don't know how to create the individual clips of the different animations.

I will make a minimalist demo. Would you also help me parse the animations? Because that's basically the one thing that I haven't yet added to the glb thing. At some point I'll go back to the cloth simulation, too. I want to have all of these toys in jpct.

GenericVertexController. Is there another way? Anyway, what values should I plug in for compile()?

I just tried, since I don't know what to put in for batchSize, the following. Still breaks the animation.

obj.compile(true, true, true, false, -1);


Now I want the same code to also work with OpenGL. But I'm getting:

QuoteException in thread "main" java.lang.NullPointerException: Cannot read the array length because "this.texels" is null

I can do compile(true) and not lose animations on Raft's bones. But it breaks the animations on my GLB models with my own bone structure. Is there anything that I should be overriding and adding? If not, would you have a clue as to what's doing this?

Thanks a lot. It is unnecessarily complicated, though, isn't it?

I tried texture.setAlpha(). Even tried replacing the texture in the texture manager. It doesn't change the object's opacity in any way.

So is there no way to do a proper fadeout?

I thought that it was a color thing that nothing I do makes an object fade in or out with the software render. This is a basic test I wrote (several different attempts in there, none of which work):

If I'm not mistaken, the software renderer works with 16 bits for color (and a third byte for transparency?). Is it trivial giving it all 24 bits (plus a byte for transparency). If so, would you?

Please try to search for a topic. It doesn't fail sometimes, it fails every time.
