If you watched my last tutorial on exporting STmaps from Blender to apply your lens distortion in whatever compositing program you are using, I’m happy to share that I have an update that improves the process in every way!
If you haven’t watched that one, check it out HERE, or perhaps this one won’t make much sense. Scroll down a little for the video.
I’ve fixed the small issue that resulted in artifacting on the edges while compositing, and I’ve also made it a node, so now there is no setup on your part (well, you still need to create your base STmap). Create your STmap base image, enter a few values, and save out your undistorted and distorted STmaps. Quick and easy!
