I just installed CentiLeo and had a bit of trouble getting it started because I used the typical C4D method for installation:
- C4D > Edit > Preferences > Open Preferences Folder
- Copy plugin into the User Prefs folder
C:\Program Files\Maxon Cinema 4D R21\plugins\CentiLeoR21
And was able to get it to run.
If it's technically feasible, please allow users to install in the User Prefs folder - installing to Program Files requires Admin Access and can sometimes slow down jobs as you need IT Support in order to do the installation.
