I have this model with a very sharp angle on the edge between two faces and this is causing some rendering issues.

Is there a better way to model this sharp edge? Its not entirely flat o the x/y plane, it has some inclination.

1 Answer 1


Following advice from @Duarte in the comments I added thickness to the base of the model.

In case someone finds this issue the steps I used to add this extra thickness in this model were:

In edit mode:

  • Set the view to -z and select all faces.
  • E, ., 0 and 1 (to extrude by 0.01)
  • Shift+A, G, Z, ., 0 and 1 (select all and move .01 on the z axis)
