Geo update issues using Bake Texture and Wedge ROPs

[GeordieM]

Hi all, I'm attempting to generate a tangent space normal map of a large terrain using Bake Texture ROP.  It keeps failing due to geo size so I'm attempting to render tiles.

I have two object nodes, one merges low res tiles from main terrain and other merges hi res tiles.  I'm using a Wedge ROP to drive X and Y parms on an object which the tile objects reference to change the tile they display.

This all works fine, except the Bake Texture ROP doesn't seem to refresh the bounds of the tile objects between Wedge iterations.  It renders the tile in the space of the entire terrain.  What's even weirder is I added  bounds and match size SOPs to the tile to scale it to the entire terrain size, and it still only render tiles in terrain space.

Is there some magic I need to do to get Wedge renders to update SOP graphs correctly?  Does the last SOP graph node need to reference parms driven by the Wedge node?

I've attached an image of the output, as you can see it's correctly rendering the tile, just in the space of the entire terrain.

Thanks!
