• [ ] waiting for ready to blender 4.0

Now Modes are good:

1. Only indices for vertices, edges, faces without object indices

2. Indices for vertices, edges, faces with (!!!) object indices

3. Only text for vertices, edges, faces without object indices )

4. Text for vertices, edges, faces with (!!!) object indices

Hi @zeffii ! Can you test this pull request? I force to work this node in a mode with multiple objects with custom text and property "Draw Object Index" is On. But I think this node need global refactor ))) (not now)

P.S. Also I simplify using shaders to a single shader draw_indices_2D_wbg without draw_indices_2D. draw_indices_2D is a very simple and it differ only by a background rectangle. May be draw_indices_2D is not need any more?

All was hidden with that configuration of params:

Fixed.

[zeffii]

the ghost icon-button is for hiding backfacing indices, so only really works when user passes polygons too.

I get this glitch after exclude draw_indices_2D. Now it is work good.

[zeffii]

@satabol sorry , i've been traveling and have not been spending much time near computers.

[zeffii]

i don't see anything i disagree with, but would prefer if #4983 was pushed first.

[satabol]

Ok @zeffii. No problem. I will expect it. )))
