How to animate noise in Blender 2.90

Hi everyone. Lately i’m trying to create blender based pipeline for my works. As far as i understand we can animate noise with texture nodes but texture nodes doesn’t work for now. I’ll use animated noise with displace modifier. Is there any alternatives for that situation.

I may be wrong, but although the legacy texture feature still exists in Blender (manual page here: https://docs.blender.org/manual/en/latest/render/materials/legacy_textures/index.html), you should still be able to use the Noise Texture shader node (manual page here:https://docs.blender.org/manual/en/latest/render/shader_nodes/textures/noise.html) to animate multidimensional Perlin noise. Understandably, it doesn’t give you the same noise options that earlier versions of Blender did, but it gives you a good starting point.

Thanks for help but i can’t connect shader node texture to displace modifier.

Ah. I see! So, probably the simplest alternative to the Displace Modifier would be using a Displacement Node as a part of the object’s material.

So, you can use a Noise Texture shader node to drive displacement, but you have to use an intermediary node (or nodes) to convert the gray numerical value (with floating-point precision) output by the Factor (Fac) socket of the Noise Texture shader node to a blue vector socket to connect to your Material Output node’s Displacement input socket. Phew, that’s a lot of input and output…

Here’s an example from the manual:
render_materials_components_displacement_node-setup

If you want to read more about displacement, here is the manual page:

*Edit: FYI, true material-driven, geometry-based displacement only works in Cycles at the moment.

Thanks a lot dear Hunkadoodle. You’re great, thanks for detailed help.

You’re absolutely welcome! As an addendum, when I said that you could use a node (or nodes), I meant that you can get some cool effects if you throw a Math converter node between your Noise Texture node and your Displacement Node. You can even use two different Noise Texture nodes as the input to your Math node and get cool combinations.
