Export lens distortion map from camera tracker

Is it possible to export a lens distortion map or STMap for use in external software? I am getting a pretty good result calculating the lens distortion from Blender’s 3D tracker but I can’t do anything with the data.
I’m specifically trying to move it to Blackmagic Fusion.

Hello Zeke_Faust

I successfully did that.
Here is the protocol of my struggle:

Still did not get the overlap to work. It is possible to store the overlap data in an EXR, but somehow blender is cropping the result.

Hope that is what you were looking for.
