Fast Noise Procedural?

Hi guys,

I’m working with some 3d shapes inside Fusion. I applied a 2d fast noise for materials; I noticed somehow fusion freezes the texture and when I scale the object, the texture scales with it. Is there a way to keep the fast noise info to avoid scaling?

2D image in green input of the 3D object, represents material input or texture. As you scale the object in 3D scene, the texture scales with it, as you would expect. If you want to scale the 2D texture, scale it in 2D and it will be reflected in 3D. Either before render or after render, for different results.

If you want to manipulate textures that are based on UV coordinates, and object ID and material ID , there are specific nodes for that, like Texture 2D or texture transform nodes.

If you are using noise in 3D objects there is a Fast Noise Texture, that has 2D and 3D mode.

You can also use noise and other 2D elements to displace the vertices of 3D objects, based on 2D input by using displace 3D.

3D fast noise applied to 3D sphere, as material or texture input, and as you can see transparency is carried over.

If you apply same noise as input for displace node on same 3D sphere shape, you can get interesting results.
