I created a grass material, the material files and settings are as follows:
Grass001_4K-PNG_AmbientOcclusion.png [occlusion map]
Grass001_4K-PNG_Color.png [base map]
Grass001_4K-PNG_Displacement.png [height map]
Grass001_4K-PNG_NormalGL.png [normal map]
Grass001_4K-PNG_Roughness.png [metallic map]
Then I tried to pull up the grass height, but I found that the height was changing horizontally, without any vertical change. Before height change After adjustment I don’t understand what caused this, please kindly answer my questions.
Perhaps your mesh lacks or has incorrect data like normals or tangents. Can you / are you trying that on some built-in mesh? Does it look right in material preview?
I created a sphere and applied my grass material to it, but I still don’t get any 3D effect after adjusting the height map value.
This is the effect before setting the height.
It’s a very simple and cheap parallax mapping technique. Can yiu maybe post a screenshit of your expectations?
thank you for your reply
