Added two more reels over at my Works page.

TV Reel 2011
Japan Reel 2011

Added an additional page to the blog. That’s where I’ll be posting mostly some of my old/past works.

Largely inspired by the work done in the movie 2012, I did some tests on how some FumeFX (1.x) parameters would affect a crawling smoke simulation.

This one deals with the relationship between the Vorticity and the Grid Spacing.

Here is another comparison study for the Advection Stride and Vorticity when set against the Cubic Interpolation parameter.

In some rare cases, dividing a fumeFX grid into separate parts can help create a bigger simulation area. This entry will discuss a script called the FumeFX Partitioner to tackle this task.

Normal Grid / Partitioned Grid

This script will select all related particle flow nodes in the scene.

macroScript Select_PF_Nodes
category:"Particle Flow"
buttonText:"Select PF Nodes"
tooltip:"Select PF Nodes"
(
pf_sources = for i in $* where (i.classid)[1] == 1345457306 collect i
pf_events = for i in $* where (i.classid)[2] == 515064576 collect i
pf_actions = for i in $* where (i.classid)[2] == 515064320 collect i
deselect $*
selectmore pf_sources
selectmore pf_events
selectmore pf_actions
)

The first script I ever learned. Very simple, and yet extremely usefull.

$*.material = undefined

Running the script will simply clear out and/or delete all the materials assigned to objects in the scene. It doesn’t include maps and materials that are  assigned to button parameters like the Environment Map.

Here are some comparison studies concerning the relationship between the Advection Stride and Vorticity parameters for FumeFX.

Sometimes, there are scenes that require you to have a burning, moving object.  Having so usually means you need to setup a very large grid – which then leads to very slow, memory heavy simulations.

Here are a few ways to tackle this…
