Hi Micheal

I tested on stop file 219mb in size.

V3 = 13:06 mins

V4 = 2:22 mins !!!!

I am on a iMac 4Ghz Intel Core i7, 32 gb memory, AMD Radeon R9 M395X 4GB

This is great news, so much so that I really think that you should utilise email software notifications a little more, I check the forums quite regularly but progress like this really should be broadcast more widely :-)

Oh and the colours coming coming thru just made my work a whole lot easier by being able to break complex models into easier sections for export etc.

Well done, much appreciated.

Matt
