Few weeks ago I started developing a new feature to Blender: wetmaps. Being a simulator fan myself, I have always hoped Blender had some sort of "wetmaps" to allow realistic fluid simulations.

Well, now I finally started implementing it but it turned out to be a lot more. I call it "Mesh Paint" atm.

Check out some of my first tests:

Basic wetmaps:


Other kind of mesh interaction:



This system allows you to "paint" textures with other animated objects or particles. The "canvas" can be any mesh and it can even be animated. You can also specify colors for painter objects. Result will be saved as an image sequence that can be used on canvas as texture to produce preferred effect.


However, this project is still in very early stage so there is no downloadable build or patch available anytime soon. All depends on how much time I have and if I manage to keep motivated. :)

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

Blender Builds section has been changed by replacing 32-bit GCC/MinGW compiled Blender builds with a Visual C++ build.

This is done to improve build stability and bugs caused by MinGW compiler. It's also easier to update only one 32-bit version instead of two.

Blender Foundation released a new trailer of it's upcoming short Sintel. It's made using Blender and other open source software.

Sintel runtime is about 12 minutes and it will be free to download when it's released. Previous short movies by Blender Foundation are Elephants Dream (2006) and Big Buck Bunny (2008).



You can download the trailer in 1080p resolution at Blender site.


Also the Finnish company behind Star Wreck movie series: Energia Productions, have released a trailer from their upcoming full length movie Iron Sky.

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.

A new Blender testing release 2.5 Alpha1 was released today.

To find out what is new in this release compared to the stable version (2.49) check out Release Logs on Blender site.

Alpha 1 can be downloaded from Blender official site. Alternatively you can download a recent SVN 27027 from MiikaHweb Blender Builds -section.

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.)
