Hasta La Motion!

I have a simple stereo scene, where i am displacing a card to create a 2d to 3d conversion. All working except for when i try to preview using the anaglyph node.

I’ve connected up my left and right inputs into the JoinViews node but the right output is the same as the input for the read node, and not showing the displacement i have on it.

Left shows correct
Right shows input with none of the displacement on it.

I’ve double checked my workflow and its all working how it should the left and right streams are displaying correctly apart from if I connect it to the JoinViews node.

I have not had this problem before. Any ideas? my nuke file is set up for stereo.

Any help would be appreciated.

Cheers
