detbear Posted May 25, 2008 Share Posted May 25, 2008 Howdy All' So I'm working on a project where I need to simulate sand pouring out into a heap on the ground. Do any of you have a good suggestion as to how best to approach this in Hash? It doesn't necessarily have to look ultra realistic. But the more real the better. Any suggestions. I though of using a combination of dust, animated mesh and particles somehow. But I'm not sure how easy that would be. Is it possible to thicken and texture the fluid system in hash to serve this purpose? Quote Link to comment Share on other sites More sharing options...
nf1nk Posted May 25, 2008 Share Posted May 25, 2008 I would probably pull a softened cone up from under the ground plane as I had a stream of particles flow across its surface. To make the illusion work better I would put the camera in a position that we can't see inside the container that the sand is dumping from Quote Link to comment Share on other sites More sharing options...
thefreshestever Posted May 25, 2008 Share Posted May 25, 2008 try to use streaks as emitters, i guess streaks can look more like sand than fluids... Quote Link to comment Share on other sites More sharing options...
ruscular Posted May 25, 2008 Share Posted May 25, 2008 the fluid particle I used for the babyspoon animation actually look more like sand. very small particle with 0 viscosity very long render tho! I would just make the partcle at the tip where the sand being dump and a separate layer for the dust so you can adjust transparency. http://www.gentlechifitness.com/images/fin...%20fullsize.mov Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted May 25, 2008 Hash Fellow Share Posted May 25, 2008 Here's my quick take on nf1nk's idea with a succession of cones poking thru each other to give the effect of the sand cascading down the sides. sand.mov sandcones01.zip particles are troublesome in that they seem to be emitted in regular clumps rather than truly randomly.

I think your sand is good, and you can randomize the sand by adjust flow in animate mode. Quote Link to comment Share on other sites More sharing options...

You feed sand to a baby? I'm shocked. It's like letting children play in big piles of broken glass! -vern Quote Link to comment Share on other sites More sharing options...
ruscular Posted May 28, 2008 Share Posted May 28, 2008 It's suppose to be cream of baby food. I should of seek some advice on that. But the fluid particle was pretty new at the time. But at least I got paid for it. Quote Link to comment Share on other sites More sharing options...

Clever way to achieve the cascading Quote Link to comment Share on other sites More sharing options...

Brilliant effect! You could play with the particles a bit to make even better... have them... spread more at the base or just more irregular. That cone trick is VERY convincing. It is the... illusion of the sand falling down the sides that really sells it. -vern Quote Link to comment Share on other sites More sharing options...
