I want to model a tinfoil hat. What techniques should I use for modeling with tinfoil? I actually want the hat to be made of mesh (I don't want a texturing solution).
Model the hat starting from a cube subdivided with a subsurf modifier (4-5 subdivisions). Apply the modifier. Subdivide the hat (with W-->Subdivide) to create a dense geometry. With the all vertices selected press Ctrl+T to trangulate faces. Unselect everything with A, go to Select-->Random (set it's value to about 30-50%), then press Ctrl+E-->Rotate Edge CW. It'll give a bit randomness to the mesh's vertices positions.
Here is a solution with more realistic render results (but be careful with the number of polygons, keep in mind how performant your computer is). Also with a mesh by applying the displacement.
- Add a Subsurf (of 4 or more if possible), Displace (Midlevel:0, Strength:0.04 depending on the texture), Solidify (Keep that order in the modifier stack from top to bottom)
- The displace should have an aluminium texture
- Unwrap your hat - In edit mode A (select all) then U (Unwrap) then Minimize Stretch option
- Apply the Subsurf then the Displace modifier
- No need to apply the Solidify modifier
- Decide if you Smooth the shading or keep it Flat
TIP: try to have a texture that does not have too many dark (reflection) areas, as this would result in a weird displacement. Mine comes from here https://www.shutterstock.com/pic-48906235.html
