incredible thank you sir!

[@electronicinfection]

Thanks! Even though i don't no how to make the leaves on the ground stay in place. Friction does nothing to disable the wind movement.

[@qyutoclub]

That's what I am looking for Sensei! Thanks 🙏

[@Movman82]

Thank you so much

[@zezotto6687]

Looks incredible, but can you make the leafs cast shadows on ground contact? Thanks for the excellent tutorial!

[@sarkamari]

Yeah, you can make the leaves cast shadows! Just enable "Cast Shadows" in the Niagara particle settings, and make sure the ground has a proper material that supports shadows. You might need to tweak the shadow settings in your light sources too

[@Fabio-nj5ji]

Amazing!

[@CouldBeAfshin]

That is hell of a job! Thanks Reza! I wonder how to implement a Niagara system that does the same thing, but also the leaves are interactable, they can be swept away while stepping on them

[@sarkamari]

Thanks, dear Afshin. You can create a collision for your character and apply physics so that the leaves not only react to their feet but also move naturally with the wind. The Niagara system already has the collision setup in place.

Thank you! How can I imitate the movement of papers in the floor by the wind?

[@sarkamari]

To imitate the movement of papers on the floor being blown by the wind in the Niagara system in Unreal Engine, you'll need to use a combination of several modules and techniques to create the desired effect. Without putting this into practie that's how I'd set this up, Of course i am thinking out loud here !haha First, you'll want to add the "Force" module in the Niagara emitter. This module can simulate forces like wind acting on the particles. You can control the direction, strength, and turbulence of the wind by adjusting the parameters of the force applied to the particles. A "Drag" module can also be useful to simulate the friction with the ground, slowing down the movement of the paper. Next, consider using a "Turbulence" module to create randomness in the wind’s effect. This will add natural variation, like how the wind moves papers erratically on the floor. To get an even more organic feel, the "Velocity Cone" module can be used to simulate wind coming from a particular direction, which is useful for controlling the motion of the paper in a specific area. To give the paper a light and fluttering effect, you can adjust the "Size by Life" module to make the particles appear lighter as they travel through the wind, giving the illusion of weightlessness and fluttering. Additionally, using "Rotation" modules with some randomness can help simulate the papers tumbling or spinning in the air before they settle. Finally, for the movement along the ground, you may need to add a "Collision" module to make the particles interact with the surface. This will ensure the paper-like particles stop when they reach the floor or bounce off objects in the scene.

The initial slide looks great. That tinnyyyy continuous slide after it settles looks weird.

[@sarkamari]

Of course, that’s something that can be managed as well. I didn’t focus much on development since the emphasis was on the overall workflow without extending the recording for too long.

[@heroxeon]

i couldnt create a material like yours

[@CartoonChris1]

now add self collision so they stack on each other. not sure why it's so complicated in ue. I always end up back in Maya doing self collision particles in there and then saving as an alembic which is not ideal.

[@John_atCTS]

LOVE IT! Thanks Reza. Perhaps one on Flying Birds??

[@mitchellrcohen]

Yes!!!!
