I have just started teaching myself 3D modeling so that I can start making some simple 3D games in Unity. I am already familiar enough with code to start making things, but I lacked the 3D model assets. I been teaching myself Blender and created some very simple models. The problem I am finding is that I get what appears to be holes in the mesh. For example if I put the model into Texture mode I see what looks like a Face that is see through or another color. If I start moving Vertices in Edit mode I can make the hole disappear.
Just wondering what I might be doing wrong to cause this problem. I know you are suppose to try and keep all faces quads so that is what I continue to do. Basically all I am doing right now is making a flat model in a Top Ortho view and then extruding to add a 3rd dimension to the model. Am I doing things wrong? Just making a simple model of a ghost yet I somehow have this other section that appears to be a different color when viewed in texture mode.
Here is the same model in Solid Shading mode
Thank you in advance for any help with this.
