SNOW in Unity - SHADER GRAPH

[@PanCave]

Just a quick math note: 3:47 "And because the dot-product of two parallel vectors is 1" That is not generally true. This is only true, if the product of the lengths of these vectors is 1. Typically, normal vectors have a length of 1, as well as automatically initialized direction vectors, so in this scenario it's true. But it could yield to some strange effects in other circumstances. Edit: A general solution to this would be to normalize the vectors. As stated by Small Pixel, changing the direction, whiteout changing the length is pretty hard. So by changing the direction, the intensity would also be changed. Solution: Normalize the vectors

[@junpeiiori4720]

yeah he should have said "unit vectors"

[@smallpixel6874]

There is another thing - on 7:47 he changed the SnowDirection vector and it stopped being a unit one, so the dot product is not going to be 1 in this case and the snow will have more opacity than it should have on the sides.

[@esben181]

I literally just learned about vectors today so I picked that up too

[@Joacim-A]

I reacted on the fact that he, at 4:59 used a clamp node to clamp the dot product between 0 and 1, this is incorrect but doesn't matter as long as the vectors are normalized. The correct procedure would be to first normalize both vectors and used the dot product of those.

[@Brackeys]

This is very true. Thanks for pointing it out! :-)

[@GabrielAguiarProd]

It's quite an interesting shader isn't it? Thanks for the credit. Great video.

[@GabrielAguiarProd]

Here's my version just in case: kzbin.info/www/bejne/h2WWiXWvmM12e7s

[@PolyToots]

Be nice if he mentioned you in the actual videos though. This isn't the first time he's used your stuff.

[@Xadness22]

Bro your channel have really cool shader tutorial Thanks bro!I also watch your shader tutorials.:D

[@harrytaylorj]

Brackeys! One thing that I noticed in your video is when you changed the shader for all of the materials in the full environment, it changed the Base Map of all the floor!! Look closely at 13:34, all the floor has the 'dungeon_set_02_atlas_01' texture instead of their pre-existing texture. You have to change the base map manually afterwards to get the snow on the floor tile textures

[@sambojinbojin-sam6550]

Thanks Brackey. Loving your shadergraph tutorials. Always simple enough and well explained enough so that we know what you're doing, but also complex enough so I feel I can take the next step on my own with the basics I've learned to expand such effects into other areas or tweak them to be how I want.

[@leak5005]

I watch his videos and I don't even code anything I just find it super relaxing to watch him code.

[@lusun8820]

If all materials use this shader, how to make the surface of the blocked object free of snow, such as indoor, tunnel?

[@Definitely_a_Fox]

I was kinda hoping you'd use vector displacement to allow the snow to actually pile up, but this is a great video anyway!

[@ChaosCreations0]

I just wanted to say a thank you for your explanation of Dot Product, it was very concise and finally helped me to understand its purpose for future applications!

[@romisflasher]

Thank you so much! Your videos aren't the first time they are helping me out. By the way, here you can add a TilingAndOffset after the NormalVector to adjust the height of the snow cap and adjust along the "Y" axis

Hi Sebastian! i just wanted to say i love your videos, and you give me a smile every day, i really love the way you're teaching and it just sucks to see your tutorials then see someone else's tutorials.. :P anyways, thanks for making all of those tutorials over the years, and i hope you would continue doing it for a long time :)

[@hermesdavidms]

great stuff, i love this kind of tutorials. on a side note, yeah sure, mayan ruins covered in snow, instead of the usual scorching heat they are usually in

[@thehuggz-i9k]

Should have named that variable "Snowpacity" Great video!

[@Oxmond]

❄️Let it snow!!! Great tutorial as usual! 👍🤓

[@omri_st4046]

Hi I realy liked this video but I think you should do more series about creating a game (many videos about the same game), you did this before and you improved your Unity skils so much sience you started uploads videos into youtube. This is so important because every video that you upload is so helpful for me personatly.

[@NarTheNecromancer]

Is there a way to do this without having to go in and manually change the base map for each material?

[@Atezian]

Im thinking that right now. :-( its not uncommon to have 100s of materials in a project

[@brodakarat6340]

10:30 how are all the materials changed without the base map resetting to the default?

[@BJ-wz2mu]

[@albarnie1168]

a good idea is to factor in the normals and ambient occlusion for snow

[@robertmcdonell831]

Loving that BlackThornProd shirt

[@johndeleon8741]

You still have to apply the material to every object you want snow on which will affect performance. Also what if you wanted to add footsteps or skid marks? This needs to be converted into a post-process shader, I think.

[@Dante4F8]

Is the Base Map suposed to get swapped automatically? I tried to do this with the base LWRP scene but I ended up needing to swap the map manually.

[@davidmoll7250]

Short question: At 8:00 you show that we can change the Vector3-value to change the direction the snow comes from. If I make a snowstorm moving to a random position, could I change that value to the Vector3-value of my snowstorm so it always looks like my objects get covered from the right angle? How could I do that?

[@vornamenachname5267]

I think that would look weird, because the surfaces that were covered in snow would just become clear again. If you want to try it though, you would have to set the snow direction from a script according to the direction of your particle system. Just look up how to set shader values from a script.

[@Sagaan42]

David Moll you can access shader property values in script from the materials. (materials.setVector("nameOfProperty", value))

[@cameronschiralli3569]

[@softandsgame4874]

The winter is comi... Sorry it's finish :( Good effect brackeys !

[@YulRun]

Does this automatically take the previous base map? or would you have to manually add them for every single texture?

[@MizoxNG]

I made something similar to this in shaderforge at one point, but with more values, it chose between 3 different textures depending on the geometry normal, then set the texture coordinates based on the world space

[@pratibhakumari3740]

Is this dynamic like will the snow still be on top if you rotate objects

[@nonyabiness4838]

Quick question... Why would you use XML instead of JSON? JSON is smaller, faster, and I feel like it's easier to learn and write than XML. Genuine question.

[@nochtans342]

It is pretty normal to use XML for UI. properties and children are written in different ways, creating more structure.

[@nonyabiness4838]

@@nochtans342 I suppose that's true. It's quite easy to differentiate between a property and a node in XML making use of xpath queries. hmm... Thanks for the response!

[@rashiddev7545]

How about next video about Character footprints? I can't find any videos about this topic anywhere!

[@joshpeace2673]

You could instantiate a footprint "decal" with a deep hight and normal map at your foot position while walking Public bool isRightFoot; Public game object Footprint; Game object right foot bone; Game object leftfootbone; Void walking () [ Movement code here ; SpawnFootPrint (); ] Void SpawnFootPrint () [ IsRightFoot == !

[@JohnWeland]

It would be really neat to control the snow direction from wind direction over time. so on a map, if its snowing and the wind is coming from the north the snow builds up more on the north, likewise over time if the wind changes to coming from the east snow would pile up more on the east.

[@arzifactstudios2146]

Can you make a video about animation state behaviours?

[@magnusm4]

I'd love a more detailed video on the animation and animator and ways to have it interact with scripts. Like executable code in Scriptable Objects and calling methods in the animation. Like for example a method being called right when the animation of a gun pulls back the hammer which reloads the gun, so no need to program in the time it takes for the animation to finish or based on it's length

[@okaybenji]

thanks so much for this and all your wonderful videos! would you please expand on this to add the *sparkle* you’d see in snow or sand in games like journey and uncharted? the sparkles appear in randomized positions based on the position and angle of the camera, which simulates the individual grains/snowflakes having random angles and catching the light from the sun as you move around. also, since snow adds some volume/puffiness, it would be nice to see how we could smoothen and expand the scale of the models slightly where the snow shows up!

[@gameexplorer4963]

Very nice. It would be interesting to see this applied with a nice mask, to better define the borders.

[@DioSatyaloka]

[@sudhanshlone8284]

Could you please make a tutorial on how to use a render pipeline and probuilder together

[@CaseyHofland]

Did you upgrade all your project materials? (Under Edit > Render > Upgrade all project materials to HDRP / LWRP). That way ProBuilders default materials will change to be compatible with your new render pipeline (though I don't know what to do if writing your own RP.) Unfortunately, the 1m albedo maps aren't exported and the materials also don't support vector colors, though I guess if you really wanted you can modify it yourself. This should help you get started (though I can't validate its success.) answers.unity.com/questions/1516854/probuilder-default-material-with-lwrp.html When he says Material Editor, I think he means the Window from ProBuilder but not sure. Good luck!

[@sudhanshlone8284]

Yeah

[@sudhanshlone8284]

The object only shows the default color

[@CaseyHofland]

That's what I mean, they don't have vector colors so they revert back to the default settings. Like the post specifies, you need to set your own default material that you can then shape and customize, like adding the albedo map. If you want to use the vector colors I'm afraid you will have to build your own shader that utilizes this, but you would have to know how ProBuilder applies it and I'm afraid I can't help you there.

Nice tutorial, but how to add normal maps for snow (or moss) correctly? If we generate uv from world position then this uv will not match object tangent space. Normal maps for snow will give incorrect shading in this case. And I have no idea how to solve this problem with shader graph. Well, probably most people will not notice that small bumps on snow will have shadows on the wrong side most of the time, but anyway.
