Loading a model into Lightsolve

You can feed Lightsolve with OBJ or SKP 3D models. The Rhino file format importer is not always working properly, keep it as last hope.

From Rhino

• Export to SKP format. Open the file in SketchUp and check that things look correct. If so, skip to next paragraph.
• Export to OBJ format, then open in an editor and check that everything is correct (Blender, MeshLab, or even just re-opening the OBJ file with Rhino).

From SketchUP

• Check your SKP file. If it looks correct into SketchUP, load it into Lightsolve. If not working,
• If are a lucky owner of a PRO version, use the integrated OBJ file exporter.
• If you use the free version, try to load your SKP file directly into Lightsolve: please make sure your SKP file is compatible with SketchUP 2015 or earlier.
• If these methods did not work, please try to open the broken OBJ file in a viewer (Rhino, Blender, MeshLab, ...) and see if you can guess what went wrong during the conversion.
• In any case, make sure your model has materials (not just colors).
• Remove hidden object and DIVA or other virtual surfaces from your model.

Troubleshooting: in case of problems try to copy your model and paste it in a new, empty SketchUp window.

When you have the OBJ file

• You can most probably open it into Lightsolve without problems.
• You can edit the MTL file that was saved with the OBJ file and check the materials in a text editor.

If your model looks weird:

Try to recompute the normals right after loading your model (second tab, when the materials validation menu is displayed).
