Correct, mesh warping is for slices. If you look at my image of the Datapath vs Individual GPU Outputs, the Advanced Output of the Datapath has connecting boundaries because Resolume thinks its one display. If you slice and warp each of the quadrants, you can not pull your mesh across these boarders because the video will bleed into undesirable quadrants. This can't happen in the Individual GPU Outputs. I suppose you would have to add a mask if this happens.

I've never had problems with keeping slices into datapath quadrant boundaries.
If slice is out of boundary then you're doing something wrong, but even in this case you can just add mask.

That sounds like a solution then. I'll have to give it another go since I have an Fx4 here. Thanks for the advice.

About to finally give this ago go tonight.

I'm still not sure masking will solve this issue because the masks would need to be only acting on individual slices and not the slices stacked below it.

So I was correct. When trying to use every last pixel of a Datapath FX4, you are limited by the internal boundaries of the quad zones. If you are video mapping and stretch over into this area, you will need to be careful of the other slices/quadrants.

I believe the way out of this is to scale the image down so it stays within its quadrant after editing points for mapping. But then you need to scale the image at the projector using the zoom. Doing this you lose pixel density.
