As a 2D artist that has been studying and attempting to understand how the terrastalization works so I can draw it. I applaud your work in recreating the effect. Even if I won't render it in 3D. Understanding how it is made helps with trying to re-create it. ^^
I will add the disclaimer that I have no idea how they *actually* implemented this shader - I dunno how I'd even go about decompiling the game to figure that out. So I just sorta guessed, as I usually do with my "break down effect from a game" tutorials. I do hope the video helps you recreate it in 2D though!
@@danielilett We're all just attempting to reverse engineer it in our own way. But it was really helpful for me to analyse. ^^ It's a big project, I hope to finish it this month but it might take another two. xD
Have you thought about using vertex colours in the mesh instead of the texture? a random range of 0>1 in the red channel applied in Max/Maya/Blender etc would make the effect work without the need for a texture lookup and all the UV stuff. Potentially you could do all of that effect on the vertex shader then and pass over to Fragment at the end?
You should absolutely be able to use vertex colours for something like this, and it'd end up more efficient - like you say, avoiding a texture lookup would be great. I avoided doing stuff like that in Max/Maya/Blender to keep as much of this whole process "in Unity" as I could but now that I think about it, you could probably write a similar plugin as I did that modifies the vertex colours directly instead of creating a texture. I might try doing that, actually!
@@janek1633 if you get a triangle and set a vertex color I believe it "splits" the vertices, like a UV seam or a smoothing group will do, it'll increase the indices (sp?) in the mesh but will allow you to have every triangle as a different color without bleeding over into the next triangle. Though it might be nice to just set every vertex as a random color, it wouldn't be the same hard triangle edge then but perhaps a nice variation on the effect.
Instead of assigning a color to every triangle via a texture, could you use the normal vector you calculated as a kind of a seed into a random number generator? It should be mostly-unique per polygon.
You definitely could. I guess it depends on what model you have - if you're fine with a unique vector per flat section of the mesh, even if it's made of multiple triangles, go ahead and use the normals as the seed! If you want those triangles to have different reflections, you'll need to do something like my method, or as someone else pointed out in the comments you might be able to use vertex colours. At least if you use the normals, you avoid doing an extra texture sample.
Did you download the project from GitHub? If you did, then there should be a new menu item in the toolbar for the plugin: "Tools -> Convert Mesh to Terastal Texture". Clicking it will bring up a tiny new Unity window for the plugin.
@@danielilett yes, i added the project by overwriting it to my current project, but there's no "Tools -> Convert Mesh to Terastal Texture" in the toolbar
Lol man what a cool channel, awesome content! Can't wait to watch ALL of your videos :D
So cool! While I didn't care about the actual mechanic in the game, I thought it was so beautiful.
That's really cool, thanks for the video.

Thats so cool!, you should make more pokemon shader
I'm always on the lookout for more shader ideas from games! I'm sure I can think of more shaders based on Pokemon.
@@danielilett remaking shaders from games is an awesome idea, hope to see more like this!
cool man，keep doing ！
Very cool!

But vertices are shared between multiple triangles, so I don't think that would work unless every triangle has unique vertices?

@@Chris-jo1zr I see, yeah, that would be cheaper than a texture lookup
Do you know if there is any way to accomplish something similar in Blender?
