So I have this base cylindrical mesh with a noise shader on it.
As you can see the noise is constrained because of the bounds of the mesh.
Is there any way that I can make the noise come out of the mesh so it doesn't look cut off. Kind of like the mesh is radiating that noise texture.
Example below image.
A mask is a black and white image that tells a mix shader "which parts go where" when mixing two other textures (or materials). Here is an example of one I made by warping a spherical gradient with a noise texture:
When using this as a mix factor between the colored noise you already have and a Transparent shader, only the desired part is shown, and the rest is transparent, or "masked off" if you will. Remember to switch to your blend mode alpha-blend if you are using EEVEE for the transparency to show properly.
