I know that there's "Alpha sort" option to sort faces in the suppossedly correct way. But it doesn't work well sometimes. Now is that sometime.

I have some faces from an object that I need then to be rendered in front of other objects... and they appear behind. Faces to be in front are from a different object that the one (well, two) that are behind.

I know that OpenGL sort well faces... that are not translucent. Mines are all PNGs with alpha, Z-Transparency at 0.

Is there any workaround to achieve that?

This is in 3D View:

BGE (before EDIT1):

BGE (text solved with Alpha Clip but problems with ADD blend):

In fact, there are 5 layers that have to be in order: OSD, a plane with ADD blend type (hidden in screenshots), a plane with the red character (video), a rigged puppet (green jacket) and the background. Well... the dinosaur too :D.

EDIT1: I found that Alpha Clip is good for my needs, because those letters have 1bit alpha depth. But what about 8bits alpha depth images?

EDIT2: The plane with ADD blend is not rendering well. The problem now is with this object :/.

  • $\begingroup$ Just a heads up, I believe the game engine is going away in 2.8. What are you using it for? Could the new EEVEE engine work for you? $\endgroup$ – SilverWolf Dec 5 '18 at 17:27
  • $\begingroup$ I know that GE won't be in 2.8 and no, EEVEE is not for my work (maybe not yet). Also, I had so many errors by trying UPBGE. That's why on 2.79, looking for "workarounds". $\endgroup$ – Mario Mey Dec 5 '18 at 17:40

    $\begingroup$ Hm. If you're trying to make something interactive, and you're worried about the discontinuation of the BGE, there's always Blend4Web. $\endgroup$ – SilverWolf Dec 5 '18 at 17:47
  • $\begingroup$ As for the sorting thing, does the BGE support compositing multiple scenes together? $\endgroup$ – SilverWolf Dec 5 '18 at 17:47
  • $\begingroup$ Yes, I know Blend4Web, but I can't migrate to it or to UBPBG or to Armory. Now, I need to stay in BGE. Oh... multiple scenes, I forgot about that! It can be the solution, thanks! $\endgroup$ – Mario Mey Dec 5 '18 at 18:21
