Thanks for this info 😄
I did this and it works well, but with a lot to select it takes a long time 😢

I'm still looking into the QuadTools option and if I can't get them to work then I now have other ways to solve the problem.

Thanks to everyone for your help.

When you export your model to GE, it can export camera settings but it's not the dae file that bears the info but the kml file one folder level up.

Yeah, that was what I finally discovered. Maybe that's a good way to do it for GE, but that's not the right way to do it for collada.

But a separate ollada camera exporter could be written. I never did finish looking into it, but it seems pretty straightforward for a simple non-animated camera.

Ha, I forgot about this plugin. Jim, this plugin is where I first "met" you. Probably one of the first ones I downloaded. I completely forgot about it.

That's all.
