Attached Link: MD animated cloth in Cinema+VRay

MD's render engine isn't the best.  It's primary use is for visualization purposes only.  Just about every one using MD ends up exporting to another proggie for rendering.

Workflow in conjunction with Poser:

Create a zeroed .obj avatar (figure) that you want to work with (you do have some wiggle room here:  I have put a dress made for V4 onto an M4 figure, and MD easily re-fits the dress and fixes poke-throughs like a breeze!).  I also create an end-posed figure at the same time to be ready for later work.

Create the clothing in MD on the zero figure.  Once it is sewn, I import the end-pose figure as a morph target, and MD will run the simulation in (usually) less than 1 minute.  (It usually takes Poser's cloth room about 1/2 hour to 1 hour for the same sim on my machine!)

Export the final cloth to whatever program I use for rendering (since I do still image only, that's all I need to do.)  

There are some who do animation renders: for some amazing work check this out:

Quoting from the maker of the animation:

"This time layered cloth. All the cloth on the hero were simulated in one go. The result was used as an avatar together with the dummy for the simulation of the dummy cloth, again in one go. Animated in Cinema 4d, rendered with VRay. Here´s the animation."

"Oh, yeah. Ooooo. Aaaaah. That's how it starts.
Then, later, there's ...running. And....screaming."
