Consider a project that consists of separate .blend files:
The intention is to link both of those into a new file and place the character animation among the 3d landscape.
The alternative methods of creating 2d backgrounds works very well - until its time to have a moving camera shot. When both files are linked together the problem begins:
To move the character to the intended location breaks some of its animation that involve boids (the 'fly' in this case).
To move the landscape to the character breaks the shape of the landscape because it is still procedural.
To apply the modifiers in the landscape (to make it non-procedural) kills my computer.
I'm guessing I may be unaware of a specific workflow or... linking method that avoids this issue?
Thankyou for any suggestions!
