Renders/Ice Cream/lighting update

The Muse

Here is the first shot of the 2D ice cream splat for the Muse film (done in 2D Flash over imported Maya render files). The second part will be added later on this week once i have added a shadow to the udnerside of the ice cream and completed the highlights.



Dave has asked me to set up and create several render passes for his characters for The Muse. This requires me to set up Maya to run an Occlusion render pass through Mental Ray. To do this i added all the character elements (body, props) and assign it to a new render layer set to the occlusion preset. Rather than run the render in basic format, scaling down the sample rate of the render but raising the sample rate of the character and props allows for faster renders with no loss of render quality.

I have been experimenting with the sun and sky system in Maya, a system that allows the user to simulate real sunlight that affects the Maya scene and geometry. This is a new feature of the 8.5 update of Maya and i thought i would be a useful addition to several films who have scenes set outside. My first test went well for the most part until somewhere, somehow i went wrong and ended up with an odd prism rather than a well lit textured cube (see below).



It's hard to notice exactly what is in the scene but there should be a rectangle and a plane - both textured in red and green respectively. Unfortunately something in the process of developing my understanding of the sun and sky system has led to the rectangle becoming a transluscent object and the ground texture disappearing altogether. The actual sky isn't even visible. Prior to this it had been a really vivid blue gradient. More tests are required!
