Extreme bump issue

Support Materials and Textures
1

Hi everyone, I can’t understand why but blender is creating an exreme bump on a fairly dull bump map.
Here is the map:

here is the result

Here how it should look like

I tried to make the map duller with a mix node but i have to go to 0.9999 to make it look decent. And then the mix note doesn’t export (i need a glb file) so i get the extreme bump also in the external software.
I really can’t understand what’s going on. The normals are fine, the units and the scale too.
I have to prepare 10 models for tomorrow and i am stuck with this and cant go on.
Thank you for your help :slight_smile:

  1. Welp, You have Displacement map there, not Normal/Bump. Here is link to my own mistake on it :sweat_smile: Issue with baking normals from Multires
    Plug texture to Normal Map node than to Displacement output and enable Displacement on Material tab(right panel), I believe it was under Settings submenu

  2. Blender tends to overdo the Bump strengh, You will very rarely go with 1 Str and 1 Heigh on sliders.

P.S. oh and I do not know if Eevee support Displacement yet, I suggest to use Cycles or google if Displacement works in Eevee render engine

yup, wrong texture for the bump slot.

A normal map is blue\ish, a displacement map is a grayscale map. Or even just a red channel.
