Discussion - proposal to extend !TEXMAP specification

[Roland Melkert]

Reason for banning overlapping geometry is very much practical, as it leads to a lot of trouble when rendering it, such as z-fighting

I would suggest to only allow this inside a "LDraw Texture" subfile.

A renderer should just disable the depth buffer for awhile.

The ldraw code should enforce that by a begin end block, e.g:

Code:

0 !LAYER START background
<normal ldraw lines>
0 !LAYER END
0 !LAYER START text
<normal ldraw lines>
0 !LAYER END

Naming the layer could be optional.

Alternative would be to always disable the depth buffer while rendering ldraw code to a texture.
No layer indications would be needed in such a case.
But authors must understand it's 'first come, first served' in such a scenario.
