I am new to Blender and want to make a floating island 3d model so I started making the rocky bottom part

I followed this tutorial (https://www.youtube.com/watch?v=-RQ7PDzPVAc) and this is what I got:

enter image description here

The model and the textures are too pixelated and streched

The tutorial dude told me to do Unwrap and I did but it still does not look good

What can I do to make it look better?

Here is the blender file: https://drive.google.com/file/d/1_xTGWMflZUGOxhISmZIw3c2dS3ntSCL_/view?usp=sharing

  • $\begingroup$ Welcome to BlenderSE! Try adding more vertices or smoothing it maybe. $\endgroup$

There are 2 problems here: Your mesh has adjacent faces that are 90° or more, therefore this bad stretching effect. And as you've unwrapped with the basic Unwrap mode, the texture ends up wavy because it is how your mesh is.

You could remesh it in Sculpt mode in order to clean the topology, press R to choose the quad size and CtrlR to remesh, first remesh with large quads to smooth the whole mesh then with smaller ones to have a denser topology:

Then find a rock texture and sculpt with the Stencil:

Then unwrap with the Smart UV Project mode and paint a rock texture with the Stencil.

As for the Remesh tool in Object mode, go into the Object Data panel > Remesh > Quad:

  • $\begingroup$ In that case you first need to clean the topology, you can do it with the Remesh operation in Sculpt mode (R to choose the quad size then Ctrl R), then use a rock image as texture and sculpt? $\endgroup$
