Understanding Bifrost - Simulation Scale

[@TheIcemanModdeler]

Bifrost in Maya 2016 is extremely buggy, even though I set it to use half of my ram it uses all of it, and on one particular scene bifrost just won't cache the entire sim only a portion of it, also if I set a custom cache location for the scratch cache it caches in 2 places at the same time, the set location and the default location.

[@raskal8578]

That's your fault. You should just take out half of your ram from inside the computer, extend your sim time, and set your custom location to the default in project setup.

[@TheIcemanModdeler]

Good job posting a year later for an issue that was resolved in service pack 1, it doesn't matter how much ram you have or don't , Bifrost in Maya 2016 without any service pack used up all the ram when using an accelerator in the scene, if you don't have a clue what's going on stop posting.

TheIcemanModdeler dammit darth, just because they killed your family, took your woman, and chopped off your jerk hand don't mean you not take a joke.

[@TheIcemanModdeler]

It's true i also lost my sense of humor along with most of my body, i need robots to help me smile.

[@raskal8578]

TheIcemanModdeler Ouch, if only big hero 6 nanites existed in your time...

I don't know what kind of a monster machine you are using but I am never able to cache something on 0,020 resolution! It's either the RAM or it will generate 10 frames in size of 10GB. Maybe it worth uploading a tutorial which would explain how you can sim relatively realistic water without having a mega machine and 4 hard drives!

[@Autodesk_Maya]

What kind of machine are you running? These tutorials were done on a 2.8GHz dual with 16gb of RAM.

[@BakaNimate]

how is this possible I am having 4.4GHz with 32 GB ram and I am trying to fill up a glass which is 12cm. Scaled the scene the way you mentioned in this tutorial but I am certainly not able to run on such a fine resolution! 10 frames cost me 8GB!

[@Autodesk_Maya]

Hmm, that definitely sounds way too big. Try lowering the Render Quality / Max Particle Display Count in the liquidShape node.

[@BakaNimate]

will this effect the accuracy of the fluid sim!

[@Autodesk_Maya]

No, they're just display options.

00:30 default surface tension of water…it's normal Standard physical formula or software implement the method？i don‘t think tension is link with the "s"(time)

[@scottimation]

Seems like the opposite effect is happening once you change the gravity and other settings. The "much larger" scale of volume is actually filling up twice as fast as the initial setup. If the 1/100 is the supposed setup, and your vat is now 100 times larger, then you should expect the water to look like it is falling slower(farther distance) and not fill up so quickly. Right now it does so in just over 30 frames. Wouldn't then the reverse calculation on gravity be more accurate?

houdini is way

[@alekseyponomarenko9711]

I littlebit confused, if i use default bifrost setting, i need to set my unit to 1m?

[@Autodesk_Maya]

You can either do that, or you can scale the liquid density and gravity to work at unit = 1cm. See this tutorial for an example: kzbin.info/www/bejne/nHOykHyfj72BbqMm19s

[@jirayuchulacharit1298]

so to be pro in maya i had to learn physics also?

[@Autodesk_Maya]

It depends. Knowledge of physics will help a lot for effects specifically, but not really for any other parts of Maya.

[@nikhilkkannur]

in 2020 Bifrost still sucks

[@raskal8578]

I hate software that uses gravity instead of density.

[@Mattscreative]

bad commentary

[@Joe-dq2wb]

Game Engine Tutorials Really? This is useful stuff, say - compared to just reading from the Unreal release notes page...

[@Mattscreative]

Joe Behymer good luck with that kid

[@stevecollins5852]

My guess is he is trying to be "edgy" to get people to go to his youtube channel

[@Mattscreative]

Steve Collins edgy what is this the 90's lol you seem bored in life go have a pepsi or coke and sit back and watch the stars

GameDev1909 Game Engine Tutorials Nice pick up! I just re-watced daria which is what I got it from, still the video isn't that bad!
