Unity VFX - Realistic Snow (Particle System Tutorial) 

Hey! I appreciate all the encouraging comments. Thank you!

Hi, we all know that people want everything for free in nowadays but you could easily put your short tutorials into a Udemy course and get some money back for the efforts you're having to make them! That's the "money hungry me" talking! ;)

***** I'll keep it under consideration! :D

👍 :)

However, those tutorials are great to give visibility to his assets on the asset store !

"your voice doesnt sound like you just woke up" - Haha, what?

Mirza well often when these kind of videos are made, it sounds like the person got out of bed just to make the video and then directly go back to sleep. But this man got energy! Like he got a good nights sleep and a big healthy breakfast with ham, eggs and baked beans with a big cup of hot coco. Put some cream on that and some marshmallows. Im hungry now.

Thanks for watching! :)

Thanks for watching! I'll try keep it to using the default assets when possible, but sometimes they just don't cut it. When that happens, I'll try at least keep it to free assets that I've put up on the store myself. I recently updated a free particle package.

Mirza oh that's good I really appreciate it .

It's just a plane with a grid texture and an image effects stack. I think the most important ones are global fog and bloom.

You can change the colours via Preferences. docs.unity3d.com/Manual/Preferences.html

It's mostly the post effect.

It's Unity's default plane.

Sorry for the stupid question but should it load up on its own or do you have to manually add it to the scene?

You can add it to the scene/hierarchy from Create -> 3D Object -> Plane, or from the menu bar at the top under GameObject.

Thanks for the hint.

Yes.

If you watch the rain tutorial I have, I go over mist/fog at the end. You can also adapt this tutorial by replacing the snow with the mist texture and increasing the size. I also have a storm cloud tutorial which might have some useful stuff for you.

I don't have a reference for that game, but it's usually done with giant billboards moving quickly. EDIT: Yup, just checked. It's about that, but it may also be rendering to screenspace to help with overdraw.

I guessed it was non-dynamic, still a cool effect though

Thanks for the suggestion, Luis! Sounds like it would make for a great tutorial.

Not at the moment due to other obligations, but it's something that others have also suggested, so it's definitely in the queue. The more people that request a specific effect, the more likely I am to do it. Thanks for the suggestion.

You probably need to turn up your Max Particles count (and/or reduce the number of particles that you spawn). The particles are being emitted too fast and then being exhausted, causing the system to stop spawning in new ones until the current ones die.

@@MirzaBeig Damn thanks I tried it and it works! 😊😊😊

Thanks for watching! :D

Make sure your game object isn't rotated and/or your velocity module is using world space.

I removed world space from the velocity module. Which midule is the game object under. Would that be particle?

I think you have some terms confused. Modules are what you see on the particle system component. They aren't related to hierarchies in the editor.

I think im more confused then on how I started. I followed it step by step but it blows to 1 direction and it looks little funny with your exact tutorials. Im trying to watch others to figure it out but im haveing a very hard time with this engine. Mostly because most tutorials aren't as updated as yours.

If you follow this tutorial exactly as it is, then there's no reason I can think of that you wouldn't have the same outcome. The latest version of Unity is the same version I'm using in the video (5.5). I can't figure out what you're looking at.

The system should be set to world space so you can move around the emitter without moving the particles with it.

There's global fog and some post-processing like bloom and colour correction. The camera is set to render a solid dark background.

Thanks for the quick reply. One last thing. Which free assets do you recommend for starters?

I'm not sure, since it would really depend on what you need the assets for :)

Set your camera to render a solid colour.

Mustafa Öztürk do you mean duc vu

That's less of a particle and more of a shader.

If you're talking about entire rivers, oceans, lakes, etc. Walter is right, those aren't usually made up of particles in games. Did you have something else in mind?

Mirza I meant so it comes bubbles and splash effects when you go i the water

Yep, that can be done! I'll try working on something like that soon (hopefully I don't forget).

Mirza Ok thanks :)

Do you mean rain in 2D? Or the sort of distortion you see when you'd point a camera up during rainy weather and the lens would have distortion from the drops?

That's not really a particle effect, but you'd be able to accomplish something like that using a shader that distorts what you get from a grab pass behind a texture, or sprite animation.

I couldnt find that kinda sprite,then I tried to create a water bubble with photoshop and move it at canvas.But it couldnt be like link.

Mert Kırımgeri You'd need to use a special distortion shader.

Thats why I asked you to make something like that :D I am not a shader expert at all :(

It's just transform.position = player.transform.position.

thanks. I just applied to the whole sky as that was easier fix. just getting started with particles. Mostly I design levels.

Core i7-2640M @ 2.8GHz CPU, 8GB RAM, and an NVS 4200M GPU. It's a laptop...

I started from nothing and went through everything step by step. You could have used the pause button if at any point it was too fast for you.

Ok ill look through it again and see what I did wrong

I created sbow but what did I miss the sbow just stay in a circle and doesnt fall

It shouldn't be in a circle because you would be using a box emitter, and it's probably not falling because you didn't enable + edit the velocity over lifetime module.

Thank you and I have no idea how to setup a box emitter. The look of what you are using is new to me from other tutorials. I subscribed just now to learn from you. because

This is a good idea, but may not be perfect because the particle sprite, rotation, and settlement may end up different for the subemitter particle. In a detailed setting though, it wouldn't be too noticeable. Thanks for the tip!
