What exactly is your problem with Vue?  Its easy to see the frustration but hard to decipher why because I find Vue 2015 Infinite incredibly stable - like Zero crashes and I have been hammering for a week now with test scenes and animation renders. Large ecosystem and figure animation scenes.  I animate "worlds" rather than make perspective sets so really like the stability and speed improvements.  Vue 2015 is far more robust than prior releases.  With respect to importing figures, most rendering systems will require some material and texture adjustments. Because Vue focuses on the macro (outdoor environment scale scenes) imported objects have texture layers merged  and maps compressed - where you find it common for Poser to have a 4mb tex file, Vue and other engines will require far smaller since its rendered in combination all the other textures in the scene.  Often too, its optimal to group and weld objects prior to import (search tips on Vue optimization).  Also merge clothes to figure.   For this reason I will get better consistency by using the texture atlas to merge Poser or DAZ texture layers to a single texture map per obj, or 1 per figure group.  Animate if necessary and export as animated Collada (dae) retaining groups, textures and keyframes.
