Quote - > Quote -  No sooner had I pressed the "post" button, I received an e-mail from E-on advising of a Vue 7.5 xstream PLE download.  I will give it a try and report back ... fingers crossed that it does not nefariously interract with any other software on my 8core, up to and including C4d.

I got that same notice today too about the 7.5 PLE. Hopefully that will help you and I would be interested in knowing myself. Right now, I use Modo and Poser Pro on my Mac Pro and soon plan to add "Mudbox" from Autodesk Mac version as well. I can say that it works fine with those programs but I do not own C4D yet.

Let me know what you find out and best of luck.

Well, here's what I've encountered within just a few hours of use (Vue 7.5 xstream PLE and C4d R11 latest build and Mac OSX 10.4. ... latest version, 8core 3.2 Ghz Mac with 4gig ram.):
There were no less than 5 crashes and these were system crashes ... no way to force closure. I must say that they ocurred most frequently with the assignment of materials and or use of the material editor.  In addition, I noticed that some of the Vue materials do not render properly in that they look entirely different when rendered than what is seen in the material manager, or for that matter, when the same materials are used and  rendered via Vue 6i on the same machine.
Loading a scene should bring up the sky or atmosphere window but it does not.
That's all I've noticed so far but I plan to put more time into it tomorrow.

BTW, I have been using PoserPro to create characters which are then imported into C4d via Interposerpro for animation.   C4d offers so many more possibilities than Poser for animation, scene creation, rendering, etc., but there is a learning curve and, of course, it is relatively costly but all things being equal, it's a bargain ... it works and works well on the Mac and I have zero issues with it.
