Blender wetmaps breakdown

Jun-07-2011    0 Comments

I just found out about this great Dynamic Paint test by CristobalAtria. It shows very clearly how and why to use wetmaps together with fluid simulations to achieve realistic renders. So if you have been wondering what wetmaps are good for, check this out:

Testing Blender Particle Fluids

Sep-24-2010    2 Comments

Yesterday jahka committed an update that fixes most particle collision stability issues. Previously SPH fluids were quite much unusable due to stability issues. Fluid kept "exploding" randomly no matter the settings. Now, after the fix, it seems very stable.

Here is a test of a pool being filled with particle fluid. No way you could have done this a week ago, but now I see no stability issues at all!

Too bad Farsthary hasn't finished his fluid surface generator. Now one can only render fluids as particles or as a volumetric texture. So no reflections or transparency is possible. :(

In case someone is wondering why I'm not writing the Dynamic Paint guide instead. Well, I gotta have some fun too. Particle fluids is something I've been waiting for a long time, and now as it finally works, I'm gonna play with it for a while. :p

Dynamic Paint beta released

Sep-13-2010    2 Comments

I have some good news. My "Dynamic Paint" tool is ready for another patch release!

You can download a build from MiikaHweb Blender Builds section or from GraphicAll.org.

If you want to make your own build, download the patch here. It's quite massive for a patch. Up to +4000 lines of code. o_O

It's still missing some small features / settings and some parts may not work yet. Yet it's stable enough to be released as beta. Please notify me if you experience any bugs or crashes so I can fix them.

Soon I'll start writing a guide that covers whole "Dynamic Paint" system. I guess most of the bugs gets fixed while doing that.

I also posted a new video of a fluid-like paint test:

I was just testing some stuff before uploading the patch but the result turned out something quite cool. In that render wetmap is used as normal/bump texture. Looks like some sort of 2D-fluid simulation. xD

And thanks again for everyone who donated to support this development! :)
