Blender Pointer Please?

in Technical Help (nuts n bolts)

I am just starting to try and crack the Blender nut. All I need is a simple flattened cube with a hole through it to import as an OBJ to DAZ. I can create it easily enough in Blender with Boolean difference, and then I create a single material zone, but every time I import into DAZ the hole is basically filled in. If I tilt the model in DAZ I can just see the edge of the hole's curve in the shape but other than that it appears to just be a flattened cube, no hole.

What am I missing?

Thanks

    Have you checked the surface settings? Maybe the hole is a surface that you can make transparent.

    No, there's only one material zone, which for some reason includes both the flattened cube AND the hole in the middle of it, which should have no geometry. If I drop cutout opacity of the one material zone, the whole shape disappears.

    I had the same thing happen and then thought that perhaps it was ngons and that was it. I used Triangulate in Blender and then Tris to Quads and exported and success in Studio.

    That sounds very promising. Thanks! I will try to figure out how to do that. I'm clearly no modeling guru, but I did look at the OBJ in wireframe mode and see geometry crossing the hole, which ain't right.

    Hot damn, that did the trick. Thanks Cris!

    I don't think that 'Tris to Quads' will have much effect on the triangulated mesh, at least on the faces with the holes in them, and I wonder if that might cause some shading issues at the outer corners.  A Remesh modifier with default settings will give you all quads, though a few around the edge of the hole have convex edges.  Also worth looking at the 'Circle' operator offered by the Loop Tools addon: this can makes a circle out of a square of edges, so if you do that on two opposing sides of a (subdivided) cube, then delete the faces within the circles and finally bridge the edge loops that form the holes, you get quite good topology, all quads with no convex edges.
