Vector4 Input on Texture 2D node

Hi,

I know this had been requested before (https://shaderforge.userecho.com/topics/746-vector4-input-on-texture-2d/) but not implemented, as the problem could have been solved using existing nodes.

However I am facing a different problem. In my shader I use a procedural noise (for the clouds) instead of a bitmap texture and want to create normal map based on this noise map (=height map). All the normal reconstruction examples I found use Texture 2D node with modified UVs. Currently I can't plug my noise map into Texture 2D node, as it accepts a bitmap texture input only (Tex).

Currently my only alternative would be to duplicate the noise code node three times for each of the two layers, but that would be extremely unefficient and messy.

Hope the above sounds clear.

Thanks,

Juliusz
