Generate normal from noise imposible?

Why is it so complicated to generate normal from noise generator ?
I think it is the minimum to be able to do this in a material editor.
Thank you if you have a solution.

Like this but it looks like ā– ā– ā– ā– . Youā€™re better off quickly creating some noise in photoshop and converting it to a normal map with Xnormal or Nvidia plugin. Takes under 3 mins.

ā€˜The Noise Module by default deals with a range of values from -1 to 1 on the pixel level and it will be hard to get the smooth results you are looking for from that particular module.ā€™

I saw this answer but it is not the result I want.
If you can input a black and white texture in the NormalFromHeightMap node and obtain a normal map, why not from black and white noise generator ?

Iā€™m not sure, might be because thereā€™s only specific demand for it. Why donā€™t you just put a greysacle noise in the the NormalFromHeightMap node then. Is there some specific reason you want to use the noise node?

On all 3D software I used ( Octane, Blender ), I was able generate normal with noise generators. I find this very useful to create materials in the engine and instantly see the result. I like to use noise to make flat surface more realistic : little bumps on painted walls, deformations on windows, large and subtle deformations on a floor or metal, bumps on a plastic surface, dustā€¦ A pregenerated texture wont give me the liberty to create the perfect bumps. A lot of objects have noise like deformations. Also, normally with the generator you can generate checker board, marble, sine waves, fractals, circlesā€¦

PreparePerturbNormalHQ and PerturbNormalHQ are two nodes that work in this scenario. Make sure to untick ā€œTangent Space Normalsā€ on the material properties

Thank you :slight_smile:

Old but gold. You can easily get nice effects using Transform Vector and Pre skinned position.

This function is so convenient!!! I drew a grid using math and changed it to normal
Draw grid and change to normal map

What were your settings for the noise node?

Iā€™m sorry for waking your post, but in your image I donā€™t see what you are doing with the pre-skinned position node, can you show the further steps?

plug into a custom UV to drive the noise from
