These are 4 tests that I threw together to test Maya 2009’s new nParticles liquid simulation option. I compared it to RealFlow, a fluid and particle simulating standalone program to see how the results held up. Overall Maya’s nParticles did pretty well, better than I expected and could probably cover most simple liquid simulation needs. -Additional Test Information- I tried to keep the simulations pretty equal for things like particle count and the radius of each particle in the end result to make it about as even of a challenge as I could. From what I saw the mesh output option in Maya seems to be about as fully featured as RealFlows, with support for motion streaking, vertex motion baking, smoothing/filtering, so to save time I opted to do test renders with simple Maya Blobby particles in the software renderer. I did not see an option for wet-maps in Maya, though. Test 1 – Ramp Splashing In this test I wasn’t too sure what I was going for, just first starting to play with nParticle liquids, so there’s two pointless extrusions, I guess they break up the flow a bit more for some interesting effect. I had the emitters fill a bit of the ramp, blocked by a plane that jumps out of the way after a bit. After playing with this I was pleased enough to do a few more tests. Test 2 – Objects Splashing The objects were simulated before any water, with their animation baked beforehand, so they are not in any way affected by the particles. On that note; I couldn’t find any way yet to …
For those of you who like the original look of early 60’s classic muscle yet with some custom touches, we here at Streetside Classic Cars have the perfect car for you; a simply incredible 1961 Chevrolet Impala 2dr bubble top. With all the right custom touches to bring this gorgeous Impala to the fore front of what makes an awesome looking and driving classic car. Showing only 2003 miles in the digital dash’s odometer since this car was restored and sporting a show worthy 454ci V8 under its hood this gorgeous ride is ready for the next car show circuit or to drive and enjoy. Walking around this magnificent 1961 Impala, you can’t help but notice the great Red paint job and the custom polished 16″ American Racing Torq-Thrust wheels which are wrapped in performance rated radial tires (225/50/R16 front and 265/50/R16 rear). Depending on the setting you’ll either see this baby sitting at normal ride height which looks factory and does not even give a hint that this ride is sitting on air. Hit the under dash mounted front and back switches with gauge to lower this ’61 Impala just about to the ground for that ultimate slammed stance for when you pull up and park at a show or just blow all the on-lookers minds when you park this baby at the local store or cruise-in. Bubble tops are one of the highest desired Impalas and this ’61 will go to the top of nearly everyone’s wish list as it’ been built to take home some trophies from car shows. Lifting the hood reveals the show-worthy …

how are you doing 48,000+ nParticles with 4 cores man, i have 8 cores and 8G ram but i’m waiting more than 3 hours to do simulations for just 20,000+ nParticles only.. shed some light here please :D
looks like Realflow really loves splashes and Maya’s fluids are much heavier
realflow = good but maximum ram used
maya = does not require much memory but its bad
this i great and all, but I have to say that from these demos realflow looks the most natural.
Maya 2012 nParticle simulations are meant to be multi-threaded now, i believe? Should be interesting!
thanks for the insight.
awesome comparison. could you do this for realflow 5 and maya 2011/2 too? =)
That’s not RAM, that’s Virtual RAM
lol :)
Oh, 6 months ago I made that comment:D
oh and i type too much now my hand hurts lol.
only 50%CPU usage at that res and that much ram and processor speed. Thats whats freaky
What’s freeky? :)
hey you can easly get 16Gigs of ram for no money and no scrounging in the trash just changing settigns that are already on your computer and it is so easy right click on computer click properties go to advanced tab then click settings then go to advanced tab again then click change then uncheck system managed and manage all rives then click custom size then type 16000 into both boxes then YOU MUST HIT SET then click ok then restart your computer if it asks you. and there you go!!
thats freaky…
oh and it is dual core
it only has one core and its very slow but it is very well cooled with only one fan for the processor and a monster of a heatsink so the temp is fine i guess it’s just plain slow but my new computer is much faster and dont get 100% used the whole time i use realflow and it is so much faster and stable but it gets pretty hot so i have to watch out but it rarely gets over 72C simulating realflow and it is idle at 45C
I think realflow had a much better physic quality
Sorry, yeah all the times are in hours:minutes:seconds, with hours only showing provided it took that long. All of these scenes were run over the course of one evening, so the longest test would be the second one with objects crushing particles, where Realflow took 3 and a half hours.
“I will guess that your computer is slow.”
Based on…? Everything that is properly multi-threaded (RealFlow, Maya at render, or really any app 3D/compositing when rendering) ran just as expected, and relative to HP workstations that should provide the same or even slightly greater power my Q6600 setup tends to edge ahead in rendering/particle benchmarks.
Suppose if I drop a grand on an i7 I might get ahead a bit, but doubt the price/performance would be justified.
I will guess that your computer is slow. If it’s not, open the task manager to check that no other software is hogging anything, run a virus scan, get antivirus software if you don’t have it and make sure that the amount of threads in the settings is the amount of processor cores you have, unless it’s got hyperthreading technology.
RealFlow wins hands down. Faster, more accurate, overall better result.
had 5 emitters and res at 200 and cpu usage around 50, i7 and 4 gb ram 2000mhz:d
Love the 61′, but OMG that warehouse = PRICELESSS!!!
killer car i like it
I cant see youre brake caliburs,are those just covers?
AGREED!!!!!!!!!!!
Hot{Rod}Damn Diggiddy Dog Giggidy Goo!………………….or just simply put: OUTSTANDING!!!
There’s a few details I don’t like but still, over all, a very beautiful car.
what a waste of a once beautiful car…..shame
Just a different taste. Very nice indeed!
i love the car it’s awsome but the dig dash make it testless .
