I have a semi transparent 3d model that I have created in Mathematica and exported to 3ds, and obj file formats. Once I open the 3ds, obj files with blender or GLC Player, the models are not transparent any more and I cannot see through them. Do I need to set some extra flags to Export to tell mathematica to retain transparency in color information ?

  • $\begingroup$ AFAIK Export does not support Opacity directives for 3ds and OBJ. $\endgroup$ – Yves Klett Apr 24 '17 at 14:30
  • $\begingroup$ For which extension it supports opacity ? $\endgroup$ – Neel Basu Apr 24 '17 at 17:02
  • $\begingroup$ If the alpha/transparency is on the whole object, could you not just import the obj file into say blender and edit the alpha/transparency of the material on the object to make it transparent again? $\endgroup$ – pfactors Apr 24 '17 at 17:36
  • $\begingroup$ But to answer your question Neel, the only 3d format that I know that may take into account the opacity is the POV ray script format in its 'pigment' setting. $\endgroup$ – pfactors Apr 24 '17 at 18:27
  • $\begingroup$ You could try DXF export with colors. Colors should be fairly easy to use as distinguishing elements on which opacity can be applied in your software. $\endgroup$ – Yves Klett Apr 25 '17 at 18:32
