Hi! how can I make the normals of the material always look at the camera? I can’t find a solution.

you add the camera location to the world position and normalize it. you should have a world normal that faces the camera. then you can do whatever. tangent transform or whatever math you require.

I’m sorry, I don’t understand how to work with spaces and location, how they interact. Can you show me?

There is a node called the camera direction vector. It will point in the direction the camera is looking. Multiply this vector by -1 and you will have a vector that points towards the camera.

Either disable tangent space normals in the material details, and use this vector as is, or transform the vector accordingly to use in tangent space.
