[Help] Portal Facing Wrong Direction

I am developing a plugin involving portals (block id 90, not the structures), but my portals are facing the wrong direction. They always face the f=1/3 direction. How do I change the orientation of the portal?

example:

 

i may be wrong, but i think the direction they render in is decided clientside...

again though, i could be wrong.

 

I can't find any data values on them so they might be aligned client-side, try removing that lapis block behind the portal from the right, if that works, then you can use another "transparent" block there instead... stairs, fences, glass, chests, anything that doesn't link fences and any other client-side aligned block.

EDIT: Ninja'd :}

 

Well, that's rather unfortunate, removing the back lapis didn't help. It seems it must be client-side. I suppose I'll just widen the portals or use water instead, thank you.
