Hey, you want to destroy a city. For the moment the item is ready to bomb and then tear apart a couple of buildings as well. A bomb made ​​em fluid4 plugin. Great for the plugin. Continue soon.

Looking nice. Would you mind posting a shot of the ICE tree? And maybe a little video of the effect?

Hi, I make a pic later, and can be slow motion animation. Succeeded nicely set up the volume shaders and fast rendering. I hope you will get see.

There are other things too, so things go more slowly

you could:

(1) not use any fractal in density, just use a LOT of particles... or
(2) you could use a mix or something in density and get a attribute from your particles as the weight for the mix... the same attribute used to switch inbetween fire and waste... (I dont know if that is clear enough, but Im not in front of SI right now to send any screengrabs)

Ok, some images so I sound more convincing... Im getting a custom attribute into my render tree... As that scalar value is closer to 0 it falls toward the particle shaper, as values get closer to 1 it falls to regular round shape.

You could use some scalar math nodes to build a mixer and not have to convert values to color, but Ill leave that up to you ;)

Thx Gustavo, I do not understand why mix the alpha two point clouds? I need to work on it.

Just a test, smoke is not good, seems to be foam. Otherwise it is 100 frames in 4 seconds for 20 seconds in slow motion.

Hi!

Did you thought of using the grid render option of the BA_shaders..? Right now you are rendering just particles and this always leads to the same problems...flickering, noise etc..
I think Eric gives some shading exapmles in his actual version of emfluid4. Though, to get nice results, the grid of the fluid must be quite hires...
Here are some test on this:



..and even Holger talking about his shaders at the UeberTage meeting 2011 (German though..)


cheers,
oli

Hi!
Sorry, I just saw' hat you are using the Fluid shaders already...just saw your tree at the first image...well, to improve this, you may work in the alpha and color gradients you are using. The fractal also seems quite noisy. Difficult to tell...

Oliver, how can be activated grid render option ba shader? where is it? indeed there are some problems, flickering, noise. Now I learn into the ba_shader never used before. Sorry for spelling and other errors.

Hi!
Well, I can´t read your tree you posted on the first page good enough, but I think, you already us the BA_fluid node wich does exactly that. I can´t see if you are getting the scalar value out of emFluid (via BA_fluid_value_float) and pipe into the BA_fluid node. As I said, have a look at the examples Eric provides in the samples..
The flickering may be caused by other settings though...but the grid stuff mostly works quite flicker free..

cheers,
oli
