No apologies needed Paolo.

Daz never had decent documentation but users could stumble through and figure it out, however, I feel that the software's sophistication has grown to the point where this has become too burdensome.  Developers can't expect folks to just pound buttons and eventually learn it, even if it is free.

I bought Reality4 but it's not been the most stable for me in either Poser or Daz.  I eagerly dived into IRay with all four paws but smacked headlong into the bottom of the pool.  Most of the settings/dials/buttons/gauges/switches/levers and other controls are arcane and seriously unintuitive.  Many didn't do anything that I could tell and others where wildly responsive.  I chucked it after a week of wasting time and went back to Reality.  Even if it crashes/locks-up/goes away every three renders, I'm still much further ahead than staring at IRay and asking my cat for suggestions.
