This week I've been working on "textured painting" for my Mesh Paint tool. Basically you can use object material/texture to define paint color and strength.

This works on both solid and volumetric materials. Texturing can be used to add some randomness to paint coverage or even better: to allow painting with smoke! You could make dirt clouds that affect environment etc.

Here's a short demo of smoke domain being used as textured "Paint" object. Painting with smoke:

My smoke patch is now in Blender trunk! Just grab a build later than SVN r30809 and try it out.

Update includes my new smoke patch and some additions by Daniel Genrich, including GUI adjustments, automatic particle system when creating a smoke flow and adaptive timesteps to ensure stable simulation while having high velocity fluid.

I have just finished a new patch to improve Blender 2.5 smoke simulator.


The major changes in this patch are:

Smooth High-Res Emitter

Additive Emission

Changing smoke vorticity

I have finished my fire tutorial for Blender 2.5. It took a bit longer than I thought but here it is. There is also a smoke tutorial coming soon.

Anyways, check it out here : Creating realistic fire in Blender 2.5

There is two new tutorials coming soon: Introduction to Blender smoke simulator and making realistic fire in Blender.

Here is a short animation made from one of my fire tutorial sample *.blend files. Mancandy - the master of fire.

I just finished a new feature for Blender smoke simulator: a possibility to change how smoke collides with domain borders.

The old system let smoke go through top and bottom sides of the domain but not the "walls". That caused some problems when using strong horizontal wind.

Now it's also possible to make the smoke to not collide any side or to collide with every side of the domain.


Update:

Added a possibility to change "Initial Velocity" multiplier.

Updated code patch can be downloaded here: smoke_collision_patch2_rev29368.patch
I have also updated my Blender Builds to use this patch.

My smoke simulator patch is now in Blender SVN. (Rev 26250)

Most visible changes in that patch are better support for multicore processors (OpenMP), more simulator related textures and a possibility to pass emitter particle's velocity to the smoke.

I just added a new version of smoke patch.

It's now possible to use smoke velocity as a texture and to change smoke cache compression method. (Light compression is recommended due to better performance.)

I just finished a Blender patch that allows using smoke heat as a texture. This might be useful in several temperature dependant simulations and it also allows faking some kind of multicolored smoke.


Here's a test video of two smoke flows with different heat values being colored by the heat.


I'll update Blender builds -section and add a patch later today.

A new Blender animation added to Videos section : Smoke Explosion.


It is made using the new Blender 2.5 smoke simulator and some tricks with the material. ;p
