Puzzles saved with puzzles.min.js 4.3.0+ cannot be opened in previous versions. There is no backward compatibility. Why? It’s just an .xml file. No errors, just empty tabs…

You mean there is no Forward compatibility?

You may want to improve and fix OIT in 4.3.0+. Now it works in a slightly unexpected way

OIT on. Three walls and TV have opacity 1 and supposed to be completely opaque. And pay attention to CPU usage…

That’s how it works with OIT on

That’s how it works with OIT off

And that’s how it at least should work
https://v3d.net/inj

P.S. CPU usage drops down to ~25-30% if switched to some other tab and then returned back to the app’s tab. But it grows up to 100% again if the app’s container is resized. So I suppose it won’t be hard for you to find and fix it.

Yes, you are right. I can’t reproduce this issue in Firefox. But can do it easily in Chrome by pressing F12 and resizing the browser’s window (Win7) or reloading the app (Win7/Win10). The frame time jumps to 16-18 ms and CPU usage grows up to 99.9%. No extentions. https://youtu.be/O2Rw4s_5Zbg
And in Android the frame time is also too high.

The thing is that this OIT method does not work well with high opacity objects, so you should reduce the opacity or make them fully opaque (material’s blend mode should be “Opaque”) or avoid using them.

I’ve fixed this issue already ))) Not ideal, but much better
obj.material.transparent = (alpha == 1) ? false : true;
