In my case I want to use anisotropic sampler inside a custom function, but A) shader graph sampler state node provides no control over anisotropy, so I can't wire an appropriate sampler state node into the function, and B) there appears to be no way to access the anisotropic sampler state already associated with the texture input. Select this material and in the Advanced Options, change the Render Queue to be Transparent. On platforms using the Metal graphics API (iOS, macOS), the You can now drag normal map type textures on to a Shader Graph to create Sample Texture 2D nodes with the correct type set. The UV coordinates to use to sample the texture. So, for example, if Texture resolution is 512x512 texels, the texture is sampled over the range [0-1] in UV space, so each texel is 1/512 x 1/512 in size in UV coordinates. Add two output ports for Direction and Color, and select Vector 3 for both. The shader material should be set the Unlit and the surface type to Opaque. Requires View Direction ( View Dir) and Normal inputs to sample the Cubemap. On hardware where this intrinsic does not exist, Shader Graph determines a fallback approximation.
