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. |
