Yes! Bryce4 can export a .opb object! I find this tip alt.graphics.bryce, the author
is 'calyxa' (
calyxa@saturn.idiom.com):
To export a mesh, open the mesh editing dialog (Edit Object - the one with the 'smooth' and 'unsmooth' icons on it) and type a control-D.
Bryce 4 can export meshes in:
AutoCAD DXF Files (*.dxf)
Infini-D Files (*.id4)
LightWave Files (*.lws)
Ray Dream Files (*.rds)
VRML 1.0 (*.wrl)
Wavefront OBJ Files (*.obj)
Notice: If you could not edit your grouped object you could not export it.
I have also noticed that you could import objects of different formats (.dxf, *.obj...), group them in Bryce and export them as a single mesh file.
