i am missing something about mapping a cube onto a dummy scene.
the node seems to be working but the transforms don’t apply to the scene.
ps if you get a red node (having installed opencv), there is a chance you need ApplyNearAndFar (Transform). my install doesn’t locate it for some reason and i have a copy of it in the same folder as this patch

maybe you dont need this file, i get a red node without it (12.0 kB)
