It’s not so much the Clipping values per se, but the fact that the End Clipping is about 10 000 000 times the Start Clipping.
This is because a ‘float’ only has a certain ‘size’ and if you divide a meter in 1000 pieces, you can see the difference between 3 and 4 mm, but if you divide a kilometer in 1000 pieces, 3 and 279 mm are indistinguishable….
I hope this makes some sense at least…It’s ther middle of the night here and I am having problems explaining things clearly 😉
