Hi, reading the forum posts I'm thinking that is not possible to put two textures on the same plane, I meen one on a side and the other texture on the other plane side.

I read about use two plane togheter to get the illusion of a plane with 2 textures, is this the way?

Is it true?

Thanks to all

I think that it is not possible to assign 2 textures to both sides of a pixel. A pixel or fragment has no "sides", it is assigned a single texture value and that's it. In my opinion, the only solution would be to use 2 planes.

you could also use a single plane but have the texture be double, so one half goes to one side and the other half to the other. would need to experiment with "tex_map" attribute to get it to wrap correctly.

in my project i have to change texture so i think that is better to use two plane but i'll try to understand better the use of tex-map attribute.

I 'll try to find a example patch for this attribute

Thanks for your replies,

the only way to do this is with two planes.

you can position and rotate them identical, and enable back-face culling for the front one (@cull_face 2) and front-face culling for the back (@cull-face 1).

Thanks @cull_face works fine for my project ;)
