I am trying to implement the material on the object, such as the picture below, without the texture image. I've looked for a function called "Bump Node" to implement the material, but I'm not yet proficient in this, so it's hard to solve the problem. Is there a way to implement a material without a texture image only in a geometry configuration? Or, there is other ways for solve this problem?

*I'm going to make translucent material. So I don't think it's right to use texture images.

    $\begingroup$ Totally fine to use any image texture in any material. But what you want your translucent material look like? These bump can be generate by some built-in function, but there are still considered as "texture" $\endgroup$ – Hikariztw Sep 12 at 10:34

    $\begingroup$ @Hikariztw Thank you for your answer. Updated post, please check the post. $\endgroup$ – BAK UI-SEOK Sep 12 at 11:24

Image texture is just a storage of information. In your case, a normal map will suit for 100% sure.

I use the polymer gun grip material for it, you can find it here

Basically you can do almost any materiel in Principled BSDF now.

You will need a normal map to fake the wavy surface. Connect that image texture to a normal map node to control strength. The connect it to Normal socket. The Transmission should be 1.0 in your case, and the main Roughness should be around 0 as well.

  • $\begingroup$ It's definitely changing color, but it's smooth. There's no texture. $\endgroup$ – BAK UI-SEOK Sep 12 at 12:13

  • $\begingroup$ You didn't UV unwrap your mesh right? Use project UV option $\endgroup$ – Hikariztw Sep 12 at 12:53
  • $\begingroup$ and also, use Cycles for initial material check, then switch back to EEVEE to see where to fix the problem. $\endgroup$ – Hikariztw Sep 12 at 12:54
