Butterfly knife trainer

Butterfly knife trainer

The edge on this trainer butterfly knife model that I'm making is very rough (obviously).

However is there any way to add more subdivisions so as to smooth it out without using the smooth button? If not, then what is the best way? Thanks and have a great day!:D

  • Have you tried selecting the required faces in edit mode and subdividing them with W-key menu? – Ashutosh Budhdeo Aug 10 at 15:39

    I found out how though I just marked the edges as sharp and then added a subdivide modifier and edge split modifier – MIEPIC Aug 10 at 16:00

First of, you should recalculate normals that seem to be going inwards instead of outwards (notice the slight blueish tint instead of gray) First of, you should recalculate normals that seem to be going inwards instead of outwards (notice the slight blueish tint instead of gray)

This is how correct normals look. This is how correct normals look.

Next up is to make the mesh more smooth so press Ctrl+F and shade smooth in Edit mode (or can be done in the T panel in object mode aswell) Next up is to make the mesh more smooth so press Ctrl+F and shade smooth in Edit mode (or can be done in the T panel in object mode aswell)

Without any other work whatsoever the mesh looks... uh.. ugly Without any other work whatsoever the mesh looks... uh.. ugly

However only by adding a correctly set up bevel modifier, you get very good results with not much more geometry. However only by adding a correctly set up bevel modifier, you get very good results with not much more geometry.

This is the bevel modifier of the above, please note that Width is subject to object size and obviously this knife would be a bit too large^^ This is the bevel modifier of the above, please note that Width is subject to object size and obviously this knife would be a bit too large^^

This is how the wireframe of the above looks. This is how the wireframe of the above looks.

Alternatively you can also get visibly beveled (not rounded) edges by using only 1 segment in Bevel and turning Auto Smooth on at about 30-60 degrees.

  • Damn dude! thank you very much, I figured it out for a while but I'll definitely do this when I need to! – MIEPIC Aug 15 at 5:21
  • Also, is there any way to clean up the smooth shading without adding bevels? – MIEPIC Aug 15 at 5:24
