This used to be the go to place for all things Bryce. Not too much nowadays, but I'll ask this here anyways.

I imported an .obj from sculptris and was going to boolean a portion of it to slice a flat spot on it. The imported object is being rendered as a hollow shell and not a solid similar to terrains that have not been made solid and you try to do a boolean operation on it.

Is there a trick anyone knows to correct this? I wanted to transfer the material of the negative object to form a flat spot on the larger object but all I get is a view of the interior imported object.

I experimented further. The same thing happens if you convert a boolean group to a single mesh.

Be sure that;

Select the imported mesh.
Click the "E" box to Edit the mesh.
Be sure "Solid When Boolean Rendering" is checked.

If it is still hollow when rendering, it is usually(?) the settings used in the program that had exported the mesh (sculptris , zbrush, etc)
I'm not familiar with sculptris.

I just imported an .obj dodecahedron and cut it's top off with a Bryce cube. The thing to remember is the object you are altering has to be Positive in the attributes and the Cutter object(my cube) must be negative

Tks, AS. I will try that tomorrow. I smoothed the import in "edit mesh" but may have overlooked the check box. Yessir, Bobbly, I knew that about attributes. Sculptris is a simplified ( free?) zbrush type modeler.
