Hi,

I have been developing an acid effect for a couple of weeks now, but I have run into a few problems when using both the multisop and cookie node. Ive been needing to use a multisop as i need the liquid to adapt to the changing geometry and then to corrode away that changing geometry.

I need a liquids collision area to drive the corrosion, and this all seems to work but when this is passed into a cookie (to cause the correct burning effect), it is causing the issue of growths rather than corroding away (see attatched image). I know this is due to some of the normals not being correct but is there i way of always keeping the normals pointing the same direction?

Another issue that is occurring which i cannot seem to solve either, is that i need the corrosion effect to not just occur on this object but on a wall and bolt. When i add these objects to the corrosion effect, the collision boundaries seem to be applied many times and the simulation grinds to a halt.

Im sorry if this sounds quite complicated (probably more than it should be!), but I really just need some advice on the right direction to solve this.

Ive also attached my latest scene file, so you can have a look at the effect.

Thanks alot!

Hi,

I have been trying to develop smoke without the use of pyro. The smoke I am trying to create is industrial, chimney smoke. I think I have got the particles behaving in the way I want, but the look just isn't right.

I have tried looking for some tutorials but I haven't had much luck. The problem is that particles become free and then when rendered look like large balls of cotton (as you can see in the screen-shot), but when I increase the size of each particle's texture (which sort of works) it becomes undetailed and unfocussed like the smoke example in the bottom right.

I'm pretty new to volumetrics, so if someone could point me in the right right direction that would be great! Any help will be much appreciated! I have also attached the HIP file to show how I have been going around things.

Thanks again.

Hi,

I am having problem seeing the construction plane when I open up Houdini Apprentice. I have installed it many times and I still get this same problem.

It also does not display any geometry which I place into the work environment, but when I do a render preview it is clearly there. I have checked that the display settings are all on and correct but I still cannot see anything.

Can anyone help?

Thanks
