I’m stuck with a problem that always gets me stuck while modelin :S
I need to cut two small holes in to the bottom plane of this mesh:
I realize that in order to cut nice round holes, I need more geometry (at least 8 vertices) around where the hole should be…
So first I tried to make loop cuts around the whole object, but that makes the big round hole distort and loose it’s roundness.
Then I tried to only subdivide the four big faces on the bottom plane, but that resulted in triangles surrounding the area.
I’m lost and I’m asking for your advice. How would you model the two holes into this shape?
I also tried to separate the four faces on the bottom part in order to avoid the triangles (on the outside faces) when subdividing them. This approach was ok otherwise but rendering shows this strange behaviour on the corners of the separated area. I tried to recalculate and flip the normals and I also tried to “set solid” for the shading of the area, but these artifacts remain
Here is a picture of the artifacts:
