How can I fix this skybox seam(Unity)?


there! I've used Unlit Shader Graph to make this skybox, and it looks mostly fine, but there is that annoying seam in the sky I don't know how to fix. Can anyone help?

  • I think we followed the same Youtube tutorial cause I ended up with your exact same graph.

    Anyway, I managed to fix the seam problem thanks to this blog post: https://jannikboysen.de/reaching-for-the-stars/

    Just recreate the SkyboxUV subgraph explained in there and use that instead of the Position and Normalize nodes (so plug the SkyboxUV node output to the Tiling and Offset input).

    This worked for me on Unity 2021.3.4f1.
