Aug 9, 2019 · Is there a way to find the color of a pixel (of a texture) at a given coordinate within my shader graph. Similar to Texture2D.GetPixel (). I think you want the Sample Texture 2D node. It’s a normalized coordinate, so you’d need to scale your input by the texture’s width and height to go from 0 to 1: Thank you so much!

Oct 27, 2023 · Whatever you try to draw, if you want it to be affected by underlying colors the shader and/or material needs to be set to transparent (not opaque). You may find some guidance search for “shader graph transparency” and related keywords. And try the most simple test case for experimenting.

Aug 9, 2022 · You need a SampleTexture2D node to get pixel color in texture, Use Position Node as a sample uv, the Position will give a 3d vector, you can use Split node and Combine node to extract the axis you want and recombine them, then connect it to the UV socket on SampleTexture2D node.

The Sample Texture 2D node samples a Texture 2D asset and returns a Vector 4 color value. You can specify the UV coordinates for a texture sample and use a Sampler State node to define a specific Sampler State.

Apr 11, 2025 · I want to make my outline darker than the main color of the object. I tried a lot of color… I’ve been sitting for 10+ hours for about a week now and trying to modify the shader from this person.

This example demonstrates how to set up a Shader Graph for Custom Render Texture shaders to create a self-healing deformation effect that could be used for snow, sand, etc. For this effect, we need a Render Texture that contains the pixels we want to displace.

Mar 5, 2023 · The quick way is probably to blit the source into a tiny texture using Graphics.Blit and then sample the output. In general (this isn’t specific to shader graph) fragment shaders execute per pixel rendered on screen.

These example shaders are built using the subgraph nodes. They show how the subgraph nodes work and how you can combine them to create backgrounds, buttons, and meters. The background examples are shaders that you can assign to Canvas Image objects that serve as backgrounds for other UI elements.

Dec 4, 2023 · In Part 1, we saw how we can use Shader Graph to control the color of objects. In Part 2, we will use textures to give ourselves essentially infinite control over the appearance of the surfaces of objects.

Jun 13, 2023 · GetPixel in shader graph. Is there a way to find the color of a pixel (of a texture) at a given coordinate within my shader graph. Similar to Texture2D.GetPixel().
