Question Using a Texture2D asset node as input in sampler Texture2d LOD node

Hi,

I want to use a texture in both vertex and fragment shaders, i use a sampler Texture2d LOD node in vertex (as a Sampler Texture 2D wont work), but cant reuse the Texture2D asset node.

The reason i want to sample a Texture2Dasset is because i need the texelsize, which wont work with Texture2D input for some reason.

Is there a way to do so ?

Also how do i change the texture of a Texture2D asset with code, there is no name related to the node input.

And also why there is a separate Texture2D asset, besides the normal Texture2D input ? And why cant get the texel size with the Texture2D as input ?

Also is the shader Graph generally production ready, or is better to skip it at this point ? Seems to have some strange limitations.

Thanks
