looks fantastic. getting this plug definitely.
wonder if the results can be exported via openvdb.
feature list look good. none of the samples look impressive though. how could one use this fem with all the tiny triangles all over the place.
i think if we’d change the color and not call it sand no one would actually guess that it should be sand. sand behaves differently on every level.
Believe it or not there’s a thing called parameters where you can change the result when you simulate. This R&D is simply a test with my new plugin I bought, nothing else. And I’m not sure what universe you live in where sand doesn’t act the way portrayed in my video. Also why don’t you point out whats not’s physically accurate about the properties of sand in my video i’d love to know.
well i live in bali and believe me i see quite a lot of sand 🙂
sand is very heavy and not connected. the r&d video looks more like blended oats in the morning milk without the milk. or some dust caught up in spiderwebs and dirt after cleaning out an old attic.
here are some sand slomo clips from youtube. it be very interesting to see if something similar can be achieved.

anyway i actually think it is quite amazing all i’m saying is that it does not look much like sand don’t feel insulted.
as Nick said…sand? where?
please, use hudini sand tests as reference 😉
I think this plugin shows a lot of promise. I’m sure they will fine tune their solvers as time goes on… To me this versions was sort of like let’s get it out there so it’s visible and people can start playing. I think the developers were riding on the hype train from a few months back when they announced these features. I wouldn’t have wanted to have that fizzle out. They’ve done a lot of work. Look forward to seeing its progress.
I see this in Lucid too, that water particles bunch up in groups just like the sand bunches up here in the test video. Perhaps BulletFX uses the Flex libraries for sand (I don’t know) but it seems because of the GPU optimizations (just guessing).
Houdini of course has OpenCL for voxel simulations but does not display this behavior so my guess it’s these particular libraries…
bulletFX uses the bullet physics library. it use OpenCL
