Act1 Preview

It is an animation preview (Render Blast) for PACO animated short. It is the act 1. The act 2, 3, 4 and 5 should be completed by mid of next month. I spent few days to organize the render layers and render setting for these shots. Render setting in these shots have been nightmare. It is very easy to forget to turn "on" or "off" things. However, I glad that I was able to add soft body simulation on chicken's head top (can you tell me what is that call in English?), neck and their tail feather. I will add feather dropping animation in some shots and an animatable rigged feather in the last shots. The rigged feather will fly away and the camera will follows it until it reaches the main scene, the tiny town scene. Critiques are appreciated, thanks.

Motion Blur test

I use motion blur in render setting, however, the diffuse pass does not match with the occulsion pass. Therefore, I might need to find a plug-in or software to make the motion blur in post.

Act 4 Shot 1, 2, 3 sequence

Here we have our very first animated test sequence. The animator for this sequence is Jim Ward. I did the soft body dynamic effect, lighting, rendering and compositing. The purpose of this render sequence is to test our render method. Since most of our shots do not have camera movement, so we separate environment and character to two different render pass sets. Basically, we only render one frame of environment and render character animated sequence without the environment background. In order to render efficiently, we have to be very organized with our massive render pass files. We are going to put this short in stereoscopy which means we have a right camera and a left camera in every shot. Therefore we have one set of render for each camera, which means render everything twice. Here we have some numbers for this sequence.

3 shots, 5 seconds.
entire rendered frame without cut = 201 frames (402 frames for stereoscopy)
4 passes for character (diffuse, occlusion, shadow, specular) (8 passes for stereoscopy)
diffuse: about 330MB, roughly 0.5 mins per frame
occlusion: about 305MB, roughly 5 mins per frame
shadow: about 160MB, roughly 14 mins per frame
speculiar: about 180MB, roughly 0.5 mins per frame

5 passes for environment (diffuse, occlusion, shadow, specular, depth) (10 passes frames for stereoscopy) Remember, we only render one frame for environment (if no camera movement).
diffuse: about 2.7MB
occlusion: about 2.7MBe
shadow: about 250KB
speculiar: about 550KB
depth: about 2.5MB

My pictures that we render at 1280 X 720 (Stereoscopy at 1320 X 720, need extra 20 pixels for each side)

We are happy with this test and the render setting/method is successful. From now til spring break (March 10th), we will work hard on animation. We won’t have any render sequence upload there, but we will have render blast sequence upload here in this month and next month. Ok, here is some update and feedback will be appreciated.
