Two hospital CG animations

Last year I was invovled in the creation of two videos for two architectural competition for Quick-it. Both were hospitals, both in France.

First time for me to work with 3D animated people, those were AXYZ design people with manually tweaked bip files. We also tried the wind option technique with Onyx trees and custom leaves. Those were pre-rendered footage that were placed into animation with AE. Thanks to Peter Guthrie for his hints while looking for the best method to use, and espacially for providing this tutorial just at the right moment!  This can be improved but turned out good already!

Production time was approximately 1 week for the first video and 3 for the second.

Masks : Essential tools for your CG workflow 1/2

update 1-oct-2009/ thanks to Peter, I’ve learned that Multimatte workd by default with object IDs. The topic has then be corrected/completed

update 27-oct-2009/ added some info on the “Affect channel : All channels” option of a material

When it come to archviz rendering, one of the first thing to learn is to create good masks to retouch materials or objects individually in photoshop. If the most popular alpha mask allows you to cut out the entire rendering from his background, other type of masks (based on elements or objects) became essential for an efficient workflow in archviz.

I remember times where I did a second rendering with the same point of view, where every material was replaced by a self-illumated conterpart in order to save one or several DIY “masking pass” …a time consuming method, either on material editing or rendering. I even remember cutting out glass masks for buildings directly in Photoshop. Brrrrr :)

Madou Tower at Dusk

No CG this time / Even if the atmosphere and colors on CG representations of towers are often exaggerated imo, this picture of the Madou Tower (located in Brussels) I took this week may contradict me. Useful as color scheme reference for future works, with this nice Blue/Orange opposition…
