Your problem, if it is memory related , can be fixed by rendering in a separate process. This usually resolve memory leakage since FFRender, while rendering separate from Poser, will open and close as necessary, thus Poser's memory usage remains steady. Though, FFRender can sometimes remain open and begin eating your memory if there are too many items in your scene that have a texture greater than 3000 x 3000. I don't know why and neither did E-frontier.

 

I stopped rendering out to individual Tiffs a long time ago simply because I hardly ever had issues with the finished product of the animation engine. Animating to Tiffs took more time due to the assembly process. I have found that if your scene is properly setup and when all is ready to be animated, simply setting every frame for every component in the scene as a key frame solves a lot of unexpected problems. I won first place for my 45 minute sci fi presentation, beating out others using high end programs. Their features were much shorter in length because of all the procedures that went into creating their projects. I can create so much more because I don't fiddle with what I have found to be unnecessary; Thus 45.2 minutes of footage as compared to 20 minutes. Of course, I was made fun of for using Poser 7, the runner ups saying things like "why would they give credit to a button pusher" and "you shouldn't win if you don't have to work at it". You get the idea. I guess they weren't paying any attention to the story, another thing I had more time to work on instead of model construction and frame by frame micro-assembly.

I had seen recently , a person here claiming that if you use the render engine of Poser to make your movie then you're "doom from the start". That simply is not true. Rendering to Tiffs is fine if you have the time for assembly and it appears that your project is personal and not professional... so you do have the time. Try it both ways and see what is best for you. As for the pre-editing advise, that is the most important thing you can ever do. My features include some long, panoramic shots lasting about 20 seconds (600 frames). I ONLY do this for the 'Awe' value or for when the scene must capture the audience. Otherwise, the shots are much shorter in length. It might seem like there would be no substance to a short shot but I can tell you from experience, a slew of long, protracted scenes will put you audience to sleep.
