Hello, I am brand new to Blender and 3d modeling and this is my first post. I am using Blender version 2.82 and have a question about using backface culling to apply an outline to the silhouette of my meshes. This was done using a solidify modifier and as you can see I am having several issues. The brown outline does not extend to the blue parts of the bottom of the umbrella, nor does it extend to the straight part of the brown handle of the umbrella (This brown handle is a second mesh. The top of the umbrella is it’s own singular mesh as well). Additionally, the outline at the bottom of the handle is not even. Lastly, for the blue part of the top tip of the umbrella there is a blue polygon stuck inside the brown outline that is always visible and I do not know what caused this. Below I am attaching a gif of my final render, please keep in mind that I intended to achieve a flat shaded, low poly look. As I am new to this platform, I hope this gif uploads correctly.
First things to check are:
-Make sure that all of your normals are correct (shift+n in edit mode)
-Apply scale (ctrl+a in object mode)
-Set your outline material to be at the bottom of the material stack
-Make sure you are using ‘even thickness’ and ‘high quality normal’ settings in the solidify modifier, and set the material index offset to be a number that is larger than the number of materials in the stack. That way, no matter what the material index, it definitely gets the outline material set by the solidify modifier.
Hi, thank you so much for responding and for the welcome. I followed your advice and all of my issues with the handle of the umbrella are fixed. I’ve concluded that my issue with the blue polygon that is visible in the outline at the top of the umbrella is due to topology issues, so at least I know how to fix it next time. However, the blue part of the bottom of the umbrella is still not receiving any outline given the new changes, the same as shown in the gif I uploaded in my original post.
