Boolean modifier doesn't work properly [solved]

Hi all,

I’m about modeling a cylinder after a tutorial where I want to cut out some text, but the Boolean modifier doesn’t work properly. What am I doing wrong here?

TIA,

Claus

Hi, try hiding the text.

Oh, when I apply the Boolean modifier, the cylinder disappears. The text remains unaffected.

Is this is what you need?:

  • Apply the modifiers from top to bottom.
  • Enable “Self Intersection” in the solver options of the boolean modifier

Thanks for your recommendation, but although the text is now cut out, there are “stripes” in the material of the cylinder. I think this is due to the subdivision surface modifier.

Oh, this was the wrong render, :pensive:, but you can see the “stripes”.

Yeah I see the stripes. But thats a shading problem and its just indirectly related to you cut problem. The geometry that you create with a boolean operation is far from optimal here. So the topology is bad and the calculated faces normals are not fitting well. Try putting a weighted normals modifier on it. Perhaps its enough. Or you could increase the the cylinders geom density along the vertical axis to get better results, so dont use a subdiv modifer, create higher density cylinder in the first place.

Okay, I will try that.

Try putting a weighted normals modifier on it.

This helped. I also deleted the subdivision modifier. Now the “stripes” are almost gone.
