Hi,

I'm trying to create a quad which has the same normal to a quad in an object.

However, although MeshBase.quad.elms() confirms that there is 1 quad, MeshBase.quad.nrm(0) returns an access error.

When I print the memory address of MeshBase.quad.nrm(), it gives me 0x0000000...

This is despite having previously used setNormals()

Bug? Or silliness on my part?

Alternatively, or perhaps as well, is there any way I can copy the normal by using the quad vertices? I think a quad could have two possible normals, so how does Esenthel select which one? Does it have to do with the ordering of the vertices?

you want to use vertex normals (they are generated on setNormals)
VecI4 v=base.quad.ind(0);
base.vtx.nrm(v.x);
base.vtx.nrm(v.y);
base.vtx.nrm(v.z);
base.vtx.nrm(v.w);

Ah, cool, thanks!
