Thank you, gap!
Just downloaded the file and couldnīt resist to throw a quick glance at them before writing this reply.
Both are magnificient.
Without further ado I will try out the first order lense in the latern room of Flakmonkeys lighthouse.
The fourth order lense seems suitable for some smaller harbor lighthouse.
Possibly - taking other models as example - I will attempt creating one myself.
Would be a good point to start.
In any case I will keep you and of course everyone reading this thread, informed.
But - of course - it will take its time.
By the way information: yesterday I reduced the size of the Collison mesh from 50.000x50.000 to 2x2 and even 0.1x0.1m.
In either of this cases the lense was functioning flawlessly.
Henceforth there seems to be no further obstacle in creating one central fresnel file into the library folder.
