Hmm... I don't believe that was a good title... anyway...
The problem was quite evident (solved)
The branches are like, a texture in a 2D rectangle, in Blender the look is "perfect" (at least for me lol) but in sketfab it is translucent. I messed all over the materials for the branches but to no avail. I'm kinda of a n00b.
does anyone know exactly with property is making those branches translucent?
