Sorry for my rant, had been super frustrated yesterday.

I am using the latest 11.3. ... , not sure about the last numbers, 181 I think.

I use HDRIs, the IBL can load them too but I am pretty sure it does not use the full bit depth, it seems to have less dynamic, when you use te IBL so you need to resort to different methods for HDRIs.

Sometimes Poser starts with different, obviously older UI grafics... seems to happen randomly and this indicates that something is really messed up with the program. Whats annyoing me the most however is that in the matrial room the modules jump around at random locations far away and you have to scroll endlessly to find them and put them back in place and then they jump again. This happens for instance when you forget to de-select them before you close the window. The input module always jumps a few 1000 pxiels when you touch one of the inputs. This and that I dont find a way to use hair thats moving naturally but doesnt poke through the face at the same time.

You can have good looking hair with Bullet Physics and it calculates quite fast, when it doesnt have too many polygons but either it pokes through or it gets a diamond shape from collision detection (and still pokes into the head regardless) And you need a haircut thats suitable for this, cause you need to set the weights, so with most hair styles you cant do it cause you need to set the roots rigid but the rest softer. In other words it could work when you invest a lot of time, develop your own hair etc but in practice it doesnt and you only find out after you invested a lot of time.
