Standard shader with vertex colors

We had a small issue with a model with small triangles and MSAA. The interpolation of the vertex colors is by subpixel now, which can lead to some artefacts. To set the interpolation by pixel instead, change the register that contains the input color for the pixel shader to TEXCOORD10_centroid instead of COLOR.

 

Does the shader created by the graph system have a Detail Texture slot?

 

@bossa_dave, can you show us how you did it in shader graph?


-Thanks

 

just use the vertex color node in shadergraph

 

Hey guys, the shader is awesome.
Where i can download latest version?

 

good news!
While your at it, please also make vertex position animation and vertex color animation a possibility in the animator

and also the abilty to import vertex animation from maya

 

Good to hear, it's like you guys do read the forums, just a shame the implementation timeline is out of sync with our requests

Honestly vertex coloring painting/shaders should have come supported out of the box with Unity for years already as it's very useful for games..anyway SRP/Shader graph supporting in the future is good, hopefully probuilder tools improves on the tooling for it aswel thanks.

 

Just for Unity 2018 and up in the file UnityVC.cginc change all references:

half4 tangentToWorldAndPackedData[3]

to

float4 tangentToWorldAndPackedData[3]

And it works fine.

 

Is there a way to make the vertex colors emmisive if they're above 1.0f value?

 

Vertex colors are in the range of [0.0 - 1.0], it is a four byte value.
They can't go above nor below - not in Unity, not in any authoring software I know of. The mesh formats typically don't support that either nor would the mesh importer of Unity I guess.
What you could do:
Use RGB channels of vertex color to color your mesh. Use A channel to scale a constant emissive factor that would set your emissiveness to maximum at A=1.0f and to minimum at A=0.0f.

Another way to tackle that issue might be looking into "custom vertex attributes".

 

I see. But I'm asking because I noticed something about Oot3D's vertex colour shader. It's not just adding darkness to the geometry. It's also lighting it up. So the vertex colours aren't 'Lerped' but they're put on top and blended in instead.
Let me show u:





That's no light. (It could be done with vertex light, but the shader actually does the trick. You can clearly see the orange colours pop a little more.)

 

You could use some other data, like an alpha channel to contain a multiplier, then you would apply this value in the shader to your color. Now you got colors that go over the 0-1 range and you can get them glow with Bloom etc. That would probably do what you want?

 

Maybe, I don't think that's how the shader seems to work because a lot of water and waterfall streams use vertex colour alpha to fade them out. Even in the screenshot I posted above, the water has alpha on edges to 'fake' soft edge.

 

@Alvarezmd90 I thought you were talking about some generic issue and answered to that. Where above exactly? (Didn't see anything unless it's pages back in time...)

 

Above your last comment I posted two screenshots. One of which has vertex colours disabled and one enabled. It's to show that the vertex colors seem to have some sort of blend mode instead of simply lerping it.

 

Well, you could implement easily a blend mode in a shader?

 

Really? No clue how that's done.
I mean, I know how to make the shader itself have a blend mode. But it's an entirely new concept for me to put a blend mode on one layer and have it add or overlay onto the main layer of the shader.

 

Well you could easily implement blends, where shader composites texture B over texture A with a desired blend mode if that's what you want? Or any data that's available in the shader... Add "blend" would be a + operator for two values . But many of those stock Photoshop blends are quite easy to implement and majority of the math for every 25 or so blend modes is out there.

 

Yes and I think it's Photoshop's overlay blend mode. As both the darks and lights put a contrast over the scene. Right now, the vertex color shader just multiplies the color over everything. So just the darks get used. (Even though they're not as dark as the 2nd screenshot from noclip.website)

You'll see it better on that site. When toggling it on and off, some parts actually light up.

 

Yes I can see it, but is the question that you want to implement it to some shader you want to create, or add it to some existing shader?

 

I want to add this technique to the shader featured in this topic. I always use the specular one (to fully disable specular reflection).

 

Thank you and all the others that made this possible, tested to work in Built in renderer in 2020.3.15f2
