I want to have one camera following my base and a second camera following my player. However, the player tracker keeps turning off whenever I build. In the final movie I want to be able to cut back and forth between the base and player view, but this is impossible if the player tracker keeps on disabling itself.

True, I implemented the player tracker to be turned off when building (aiming for the starting phase of a timelapse).

It makes sense I guess to keep the player tracker on, I'll add some option to it so one can configure this.

I created https://github.com/veger/TLBE/issues/36 for this request

Keep following player is a new option in version 1.4.5 for the player tracker
