    Slow rendering 3D object

    julianbremann

      Hi,

      So I'm just wondering if it's normal for the render time to be that long for my project.

      I have ONLY one layer 3D object with Live 3D plugin that has only rotation and position animation.

      Project lenght is just 9 seconds! - standard 1920X1080 HD size.

      I CAPS locked the comp refresh window so it doesn't calculate the frames in it while rendering.

      I'm renderin with best settings full size, no audio, RGB+alpha Animation compression, standart 30 fps.

      I left an overnight render and in 12 hours the comp render was at the 2.12 sec (73 frames) with an estimatete left of 32 hours!

      This seems ridiculous to me so let me know if this is normal, specially since when I do a ram preview of the comp (with quarter quality preview and Draft 3D on) it takes probably about a minute or less to make the full 9 sec preview. I don't understand how a minute in preview mode turns into 40+ hours in full quality rendering.

      So let me know any thoughts..

      I'm on a i7 2.3ghz quad core with 8 gb ram mac AE 5.5.

      Thanks.

          As I wrote in your other thread, it's just how bad PS Live 3D is. You would see the same difference in Photoshop itself, also.

            Mylenium is right. I recommend against using the Live Photoshop 3D feature. You are better off doing 3D animation in a 3D program and compositing that result in After Effects.

             

            See "Importing and using 3D files from other applications".

              Thanks, I know now that nothing will improve this situation, I'll look for the other solutions for 3d rendering..

                You don't want to look for different rendering solutions, you want to find the appropriate 3D system.

                There are some fabulous 3D modeling systems on the market. Some, like Blender are free and open-source and have huge user bases. Some support refined networked or distributed rendering.

                But rendering 3D will always require three to nine times as long per pixel per effect as 2D effects in After Effects. Ray tracing and procedural effects, unless hardware supproted, siomply take time. IN the olden days of NTSC DV, we could live with it; each frame contained only 350,000 pixels. But full-on high def is a h-u-g-e CPU sucking monster. Every frame is more than 2,000,000 pixels. It's simple mathematics.
