So I was working on a mesh extruding from a plane when part way through I realized the plane I was working on was upside down, so the inside of the mesh is actually the outside and vice versa.

Is there an easy way to fix this?

It is difficult to know what you mean here?

What program are you using - Hexagon?  Something else.

Can you post an image showing what the problem is?

Yeah I’m using Hex.

Basically I started with a plane and began extruding to create an outfit but then I realized when I went to use the inflate tool I must have flipped my original plane around because inflate pushes the mesh inwards instead of outwards. I can compensate with the shift key but is an inverted mesh going to create problems further down the line, like when I UV map it.

I’m still not clear here.  There is no Plane primitive in Hex, what exactly did you use?

The grid. I started with a 2x2 grid and went from there.

I just did a little experiment in hexagon. When you create the grid, check out which way your normals are facing. The direction of the normals determine whether the inflate tool is concave vs convex. So in your case you need to orient your normals facing outward.


p.s. That title is what grabbed my attention.  LOL

I’m not quite sure how to do it in Hex, but you need to orient all the normals the same direction.  In Blender it’s easy, just select the faces that are inverted and ‘flip normals’...there should be something similar in Hex.

In Hexagon under utilities there is the orient normals tool. You can select individual faces or select all and then use the spacebar to flip the normals.

I don’t use Hex enough to know where it was…but I was sure it had to have one…almost any modelling app of recent vintage will have that tool.
