I have a collection of planes with different designs and changing their material isn't reflected in solid view in both blender internal and cycles render view. The materials I'm trying to use have been working fine for other objects.
All the planes have once been set to a pure shadeless black texture, and have had a Solidify modifier applied to them. The rendering isn't fixed after removing the modifiers. Flipping the normals doesn't have any effect.
The vertices of the planes act weird. If I add an edge, one of the triangles will be colored according to current material. If I then dissolve the new edge, it will also delete the points, even though they should be connected to the other points.
Also, the plane is rotated along the Z axis. If I Scale the plane (in object) by 1 (or anything), it will automatically align itself along the X axis (the way it previously was).
I tried to rebuild the points of the plane, and I'm not able to align/snap points to the vertices of the plane in edit or object mode. Also, I can't split the plane using the Knife tool
Currently, the only solution I have is to trace the planes.
