Poser's cloth room still is a patch-on to the engine that is based on posing and it is quite tedious to use. The move to Bullet Physics unfortunately did not bring a better interface.

Cloth room results are not really predictable and cannot be influenced other than by re-starting the simulation.

Suggestions for improvement/Poser 2016:

• Define properties in weft and warp (U and V )direction separately, with limits.
• Make sure that physical parameters of clothing are properly stored somewhere with the clothing.
• Make sure modeled folds are recognized.
• Make sure storage format includes pre-tension info in the clothing in the stored shape (= stretch of facet edges times stiffness) from an 'unstrained' morph or from the UV map. (yes, you will need to say how many poser units the 0-1 range of UV is supposed to be)
• Provide a touchup tool (not morph!), but 'pushing' or 'pulling' the clothing.

Marvelous Designer is a different price league, but I hope Poser developers take a very good look at the approach they take (or better, liaise with them and talk them into providing an add-on).

then:

• problems with conforming clothing become more apparent when the pose used differs more form the zero pose. Solution would be to provide a 'redefine this position as zero' function for figures. Clothing can then be conformed in the new zero shape and user can combine the good flow of dynamic clothing with the late tuning possibilities offered by conforming clothing.
