Hi, I have two questions about normals and Custom Render Texture Template:

- Is there a node or a function to convert height map texture to normal?

Hey there, it seems that you've only posted one question.

We provide a shader function called 'Normal Create' that generates a normal map from a greyscale image, as long as you sample that texture through a Texture Object.

Alternatively, if you're using a non-texture type, you could attempt to generate a normal map on the shader, although it would be a fairly expensive operation because it would require generating each vector component separately in order to calculate the approximate slope.
