I’m having problems with creating faces in 2.40 Alpha2. I’m working with imported 2D DXF, vrml and .cob files converted from a cad package via a file converter app. These have no faces, I select 4 verts and hit F building up the 3D model as I go.
When i create faces from the verts and/or edges in 2.4 alpha 2, I’m getting a lot of what appear to be twisted faces, where in solid view they have a greyscale gradient appearance in perhaps one or two points on the face as if a couple of the verts are slightly lower or higher on the axis than the others making up the face. In the view properties dialogue all the vertices have the same vertical position on an axis accurate to 3 decimal places, it would appear.
Yet in 2.37a if I open the same blend files and pick the same verts in the same order as I did in 2.40 alpha2 and hit F there are no problems, no twisted faces. This problem makes 2.4 unusable to me for the models I’m working on. If i render the model it looks a mess of gradients not a smooth faces forming the model.
If i open a blend in 2.37a which was edited in 2.40 alpha2 and contains twisted faces, they appear in solid view as gradients, but when i click on the faces the greyscale gradient disappears and shows solid again.
If i then save that blend with no visible twisted faces and reopen it in 2.4 alpha 2 they’re back.
Can anybody explain what’s going on?
