Automatically repeating Tileset

I’m interested in making a blueprint that auto tiles sprites similar to what you see in this video around 15:14 http://youtu.be/w5I3ljBJKa0?list=PLZlv_N0_O1gauJh60307mE_67jqK42twB
The blueprint will rotate the sprite -90 for overhead perspective (leaving each instance with a 0 X-rotation) and include a collision cube (root of blueprint).
A couple of problems I’ve run into, most important is that I can only get it to work in base 10, and most of my map is in base power of 2 already (16x16 tiles).

Less important, I found that I can either get the sprite to look right in the blueprint, or actually in the world, but not both. once you rotate the sprite it screws the whole thing up.

Any suggestions?
