Is there any way to render the normal map to a texture?

Is there any way to render the normals of a 3D scene to a texture? Ideal would be an option in the viewport to add a normalmap to a generated texture.

I need my object once rendered normally to the scene and it's normals on a separate texture for post processing. Otherwise I could just use ALBEDO = NORMAL;

I think the plan is to expose framebuffers in Godot 3.1/4.0 when Vulkan rendering backend is added, or at least that is what I gather from this issue on the GitHub repository.

From what little experience I have with OpenGL, I think when framebuffers are exposed you should be able to get the normal vectors from the rendered image for post processing. In theory, once framebuffers are exposed all sorts of custom post processing shaders should be possible.

Edit: According to this issue, access to the normal buffer will be available in Godot 3.1/4.0 :smile:

@TwistedTwigleg You meant to type 3.2/4.0 surely. :)

Thanks for the answer! So I can stop searching/thinking ;)

just started with Godot a few weeks ago.

Whoops! Yeah, I meant 3.2 not 3.1. While it would be cool if the Vulkan stuff came out in 3.1, alas we’ll have to wait for 3.2/4.0 :smile:
