Thanks, Tom. I’m not sure how cameratrackers in general handle this kind of ‘imperfect’ nodal pan (because handheld), but if I constrain the tracking and solution to rotation only the RMS errors rises to 4.2 and I am still not able to define a solid ground plane.

I am starting to think that the grass contains too few high contrast points for the tracker…

Thanks for your reply, appreciate that.
The camera solve seems to look fine. I was standing still, but the camera moved a bit (no tripod) and this is reflected in the camera track. I tried retracking using your tips and that doesn’t seem to change the camera solve a lot.
The main problem I get is when I try to make a solid that lies on the ground. On the grass there are only a few good tracking points and when I select them and make a solid the orientation is way off (and it is shifting during the clip).

Are there any tools to rotate the solid in perspective?
And if this doesn’t work, would using mocha be an option?

For the volumetric light beams you could search the net for ‘god rays’, I think that’s what they are normally called.

I guess you can use the wiggle statement to do this.
