hi im trying to render my movie and it says itll take 80 hours to render?? how do i reduce the render time?? i think im doing something wrong my movie isn't that big?

It's hard to say because there is no information regarding your scene, PC specs, animation settigns or render settings.

ok do u know how to change the rendering resolution of everything?? i changed the terrain but now everything in it is wierd? is there a global resolution thing?

Ditto!

What do you mean by "change the rendering resolution of everything", and how you could change the resolution of terrain but not other parts of the scene? You can reduce the dimensions of the output frame, but that applies to everything, not specific elements.

If you pick the Photorealistic rederer "Rendering" tab then you have a number of checkboxes at the top. Marking any one of those has the potential of increasing your render time. The same can be said of many of the other settings in that area. Experiment with the settings in there, unmarking things etc, and render single frames. Some settings don't have much apparent effect, but when marked the computer is obliged to do the calculations anyway.

Also look at the complexity of your shaders. Anything other than a simple color will add to the processing time.

If you have access to multiple computers and the right versions of Carrara (don't know exactly what versions are "right" in this case) you can use network rendering. It's easy to set up. I borrowed two computers from a coworker and cut render time to 1/6 of what it was with just my computer.

That is a little vague to say the least.

How about a screenshot or upload your file if it will fit. It will "help us help you"

I want to thank everyone for their advice, I'm sorry i am very vague about it but i don't have carrara i'm helping a friend solve her problem.. basically she has water and grass/land in her scene... her computer is really really good way above the minimum specs... and i think theres a poser model walking around..I'll try to get a screenshot off her soon... please help the rendering time is really bad.. thanks

I think it would be better for your friend who actually has the problem and the program to try and join a forum and post her problems. Since you don't have the program it's a minimal amount of help you'll be able to provide unfortunately.

does that help??

most often the "rendering time aproximation" is kinda wrong at first........like if the first few tiles of the render are complicated -ie a poser characters eyes/refelection transparency etc.......youll get a more accurate guess of the render time by rendering at least 1 whole frame first , then see what it says....do you understand what im saying ?
Using that same concept, ..and as you know what changes in the scene being rendered ...(ie does it zoom into poser characters eye/hair, or does scene get easier as the animation progresses..like more terrain iis visible) youll get more of an idea of how long it will take.
Start with single frame renders, ajusting the quality , see how long 1 frame takes and aproximate the animation time, when ur happy with that balance of quality and time, render your movie.
I notice its set to 12 frames per secound ...is that what you want ?
