Hi, I just got an Indie trial for Houdini, have managed to make a HDALC file for use in Unity that will take a curve and build a 2.5d platformer terrain. My problem is that the UVs are facing backwards. I've tried adding a Normal node and including the Reverse Normals flag in the HDA package parameters and whether reverse normals is checked or not they're the wrong way around in Unity.

I'm taking the curve, extruding it out backwards, applying bevel
create group for floor, generate UVs for floor,
create group for sides/cliffs, generate UVs
scale UVs
add different materials to different groups
normals weren't right so I added a recalculate normals node, which didn't help.

Revering the normals doesn't reverse the geometry. Use a reverse node to make the geometry right side out.

thanks! I was extruding the wrong way, so just removing the - fixed it.
