I am trying to make an interior for one of my models. I decided to use a solidify modifier to give it thickness on the inside. Some faces are extruding inwards nicely and others are not.
So, what have I tried? I have checked for and fixed; non-manifolded faces; loose geometry; interior faces. I have also; applied all the scale and rotation; manually converted the whole mesh to quads; removed any modifiers in the modifier stack; and also checked the face orientation is correct. I have also tried the complex setting on the solidify modifier and tweaked some of the options and I also did that on the simple setting. I also added a vertex group but that didn't make thing any better. Non of these have changed anything and I am starting to wonder if its not possible to make an interior using the solidify modifier and if I should instead be using booleans but I don't want to, as the result won't be too accurate. The modifier also distorts in certain places where its just a flat surface.
If you have any ideas on how to fix this, I would be much appreciated if commented on the post.
