When working with Mari it is possible to work with UV grids outside of 0-1. In order for this to be seamless the package this info will be delivered to has to be able to look at a specific section of the UV grid to know where to map to. I know Maya, XSI and MAX support this. I am unsure of Houdini.

Anyone have any insight to whether this is possible?

seems houdini can read the file with UV's outside of zero to one. Uv's appear fine in the UV view but using them is another story.

Can't you remap them using a point or primitive expression? Or you could create a new set of uv's for the values > 1 (map them to uv2 etc).

i'll try the first suggestion. The second one isn't a option since Mari does not use multiple UV's
