Grains Or Flour Pickup System

Hi, Let’s say I have a bag of grains in my game, what i want to do is take a cup put it inside the bag and all the grains goes inside the cup, i don’t know if i explained it correctly but basically it’s as same as how you would take out coffee from your container with a spoon, How can I make such a feature?

Hey @MedricitoTV1,

A few questions to get this started:

  • Are you wanting this to be an animated or just the obtained material showing up in the container?
  • Is this 2d or 3d?
  • Is this supposed to be physics based?

Any additional specifics you provide may go a long way in solving your problem!

  • I’m trying to go for realistic feel, so animated would be good, but I would like to hear the other option as well.
  • This is 3d
  • Having thousands of grains physics based would impact a performance, right? As far as I tested instanced meshes doesn’t support simulate physics, so is there any other way?

realistic feel, so animated would be good […] thousands of grains physics based

Niagara particles physics comes to mind:

a bag of grains

But what is the scope? Is it really 1 bag?

Actually, I am making a store simulator type game, where we are a shopkeeper, so there are definitely more than 1 bag, I think about 4-5, each represents different products, such as grains, flour, sugar, etc. Would Niagara particles physics be good and performant for this?

It could work OK for this. It’s pretty much the only option out there afaik. It’s a somewhat involved subject, though. If you cannot get away by faking it and need actual grains the end user can scoop up, mess around with in VR, this could be a starting point:

Thank you so much, I’ll try it out and will update.
