RV Lens Warp

Hi folks,

I’m looking for some help on using the RVLensWarp node mentioned in the docs here:

Since the cg pipeline uses undistorted scans our playblasts or lighting renders need to go through a redistortion in nuke to be able to viewed with the final lens distortion (exported from 3DE). Instead, I was looking for a way to do this live in RV so that I don’t have to re-export a distorted output from nuke for intermediate reviews. I’m a bit clueless on where to start with such an RV package as I don’t think RV ships with a sample package for this node - may be I’m wrong and there is one already.

How would the RVLensWarp workflow use distortion values exported from 3DE? In nuke we load the LD distortion node and apply the values exported from CMM. In RV’s case, what would be the input to this node as it would be different for every shot.

Any pointers are much appreciated.
