(3d scene) trouble with rendering gradient alpha texture in the engine or my rendering script?

[Surg]

Hi, I noticed in my 3d scene a strange behavior of the drawing model with a gradient alpha texture (instead of transparency, the color is “clear-color-buffer”).
When rebuilding (without changing anything), sometimes it randomly disappears. I would like to ask is this a bug in my render script or is the engine handling this case incorrectly?

So something like this?

I changed your render script to do a separate pass (another predicate) for the transparent objects as they need to have something to blend with

Yes, it works with another predicate, now I understand. Thanks!
