Creating Dirt in Maya Help...

[iekomedia]

Hello Please see attached image,

I need to create dirt going down a conveyer belt and dropping into a mold while hitting the a spinning object that kicks it to the sides of the mold. I figure the interaction part will be pretty straight forward but as you can see I need a little assistance. My friend created this in Houdini but due to the deadline of the project, I want to have a backup in case he's not able to get the results lined up. I may have to create the rocks/Dirt myself. See the second image for a sample of the type of dirt/rocks.
I am using Redshift to render so Geo or VDB is optimal.
Any help from video, to a sample scene, or walk through would be most helpful. Thank you!

If you do create a sample scene and it's exactly what i'm looking and I only need to sim,  I am willing to pay you and credit you on the final render. Thank you!

This is how it should look.

 Hi @iekomedia

Your current render looks really solid!

As for animating them to spin properly, I would highly recommend making them into a particle system if you haven't already and/or using MASH to control them.

I'm not sure how much experience you have with particle effects or MASH but it shouldn't be too complicated to make them spin in your scene.

Please let me know if this information helps or if you need any more assistance!

Hello Sean, Thank you!
Do you have any sources on what you're referencing? I've only used bifrost affects in the past for a dental commercial. I wouldn't know where to start in term of dirt and have only used mash to populate pipe molds and given random rotate on this project and as powerful as it is i haven't seen any material covering the system so I feel it's a lost system. Unless Autodesk has produced content that is not readily available outside of the traditional learning platforms. 

Anything you could provide would be helpful, thank you!

Hi @iekomedia

It's not exactly similar to what you are trying to achieve but this tutorial may help get you started!

Once you have the particles down you should be able to apply the dirt shader to it and go from there!

Let me know if this helps you out or if you need any more assistance!

Hello, 

I am currently animating the parts it needs to interact with. I will jump to the effects shortly after, wanna make sure my ducks are in a row 

Thank you!

I am back on this again for a second video. The first 360 VR final was approved because it was the first project and expectations were not as high but one of the requests from the client is that the amount of particles (dirt) going into the mold is almost 1/3 of how much it should be. I can say that it was already difficult getting that much due to the amount of particles. I realize that bifrost is really strict on making sure you group your asset and scale it down 0.01 so it is the proper size for simulation if working in real world scale. Maybe this same scaling has to be done for the nparticle system?

Well for now until otherwise stated, I am going to attempt to do a batch mix of sand and cement using bifrost. These items mix together using 4 spilling arms and it looks like a rocky road milkshake in a blender. I believe if I can give the sim some weight, give it a dry look. break up the clumps  or make it clumpy and add some collision dust/smoke. Should be able to pull it off, or am I shooting too far? Let me know if i'm wasting my time going through bifrost. Thank you
