I have simple composition that animates a two shapes that I am using as a "screen" to show photos. The shapes are 3D; the camera movement is minimal. I have an Ambient light and two Spot lights.
I am on a one year old i7 processor with 16 GB of RAM. Cache files are written to an SSD.
Still it is taking a long time to render (it's a three minute project and takes about 20+ hours to render), and there's no pics added - just the "screen".
The final project is similar to the many templates you can find that show photos/videos. It's basically a fancy slideshow, but unlike those you can buy, it will hold 25 to 30 pics.
Any thoughts on what I can do to either use something other than a 3D shape (but still keep it 3D) or change parameters or workflow to cut down the render time. . . I am pre-rendering the composition now (which will take the 20+ hours) but obviously, if I want to change anything with the movement or the overall length, it means another day of rendering.
Thanks in advance,
If you are using the ray-traced 3D renderer and are not using a GPU that provides acceleration for that feature, rendering will be very slow:
In general, I recommend using the CInema 4D integration with After Effects over trying to use the rather limited ray-traced 3D renderer within After Effects:
By the way, 20 hours is not a long time for a 3-minute composition. People who work in 3D (in any 3D program, not just After Effects) often have renders take all weekend just for 30 seconds. 3D is computationally expensive.
