    Particle strip has different UV Modes, one of them is Scale And Bias which exposes UV Scale and UV Bias parameters. However when custom shader is used, UV mode is still there and exposes the same kind of properties:

    How to access them in custom shader? I tried texture transform or _uvScale or similar things, but nothing works. Or perhaps this is UI bug and UV mode should not be available at all?

    Morning, I will check with the team, but I think that those UV modes shouldn't be exposed. Those modes also exist for Quads, and they're not exposed when overriding with a custom Shader Graph:

    So, I'm sure that you're already aware, but you could keep it to Uv Mode: Default, and Build some UV Scaling / Offset exposed properties in your Shader Graph.

    I'll come back later if I got more information to share related to those UV modes. Great day to you.

    Yeah, actually that would not make sense to be exposed as there are other options like flipbook, so it's just inspector bug.
