Quote: The way to have a normal on both sides of the face is to duplicate the faces, and press flip normals with the new duplicates selected. If you are drawing double sided an duplicating this of course will be a disaster.

This sounds like it could maybe work. Couldnt I just turn off 'draw double sided', and instead just duplicate all faces, and flip those normals? It would double the vert count for all my trees, but I see no other option...

Sorry to ask again, but how is this done in Blender (if you cant tell, im a programmer NOT a artist, and im certainly no Blender expert either :) )

edit, nevermind, misunderstood your post.
Yeah, that would work, but you may get some z-fighting from angles where both faces could be rendered.

When I duplicate faces and flip them to make a double sided plane it seems to work well, and usually I only need a few of the faces in one object to do this. So it may be better than double sided even if it seems like the face count went up.
In blender, you need to select the mesh, then tab key for edit mode, then select the faces that will be needed, then shift d is duplicate, and there is a flip normals button in the edit buttons at the bottom.

I dunno, how can a camera see 2 sides of a plane?

Uhh... lol after thinking about that, you would be correct. If both planes are rendering opposite of eachother that would be impossible.

Gah youre right if you did two planes back to back there would be zfighting..

So the ONLY solution is to get the normals to align PARALLEL with the plane (like you do for grass billboards). I dont see how thats possible without manually editing the mesh by hand.

You know what I think, I think Blender just sucks. Something about the import routine for these trees is messing something up. There is no way its a problem with the trees themselves (loopix makes quality models, no way he messed something up this bad). It HAS to be Blenders import function missing something.

Can anyone try loading that test tree in another modeler (like max) and report back if it looks any different?
