Quote - Yes, my material displacement is set for 1.75.  But how did you come up with that?  Where is the x12 coming from? I thought bounds should be a value equal to (or higher than) the highest amount of displacement in use by a material.

following is the information I got from SM support back in Nov. 2011

Quote - What you should see is that the value for your Displacement Bounds property will be your Displacement value from the Materials Room multiplied by 12.

This factor of 12 is a universal minimum bound factor. You cannot dial below this reset value or else the displacement you set in the Materials Room will not be displayed at all. While you cannot go below this minimum, you can use the Displacement Bounds dial to set the value higher.

Why 12? I am not sure where this value came from; however, it seems that if you use a Math node to make your texture more dense, then this value should decrease. (I am not sure about this and we are currently looking into it more, but this relation should hold true.)

So the quick answer is that the dial exists in the Properties because you can use it to create a higher value (not a smaller value). I hope this explanation makes sense, but if you do have any questions, please let me know!

This makes you wonder, why there is a Displacement Bounds dial in properties, when Poser calculates a value no matter what you've dialed in.
I've tried entering values in Displ.Bounds higher than 12 times displ.value and Poser did reset the value as well.
It gets even more confusing, when changing units within a project.
