      Hi,

      I am also having problems when importing 3ds file into Izzy. The original is an obj file obtained with the iPhone that is imported into Blender and exported as 3ds. I have tried changing the name of the file in case it could be a problem and I can import the resulting file into Isadora. The problem is in the distribution of the texture, which is not correct. If I open this same file with Meshlab or Blender, the texture appears correctly.



      I would appreciate any help.
      I am attaching the original model in case someone can take a look.

      Thanks

      Best regards.

      Javi

        thanks for working with this, Graham, your 3DS model is looking good in Isadora, but, even though I followed your advice, my 3DS exports are still failing to show up in Isadora. I'm going to look at this again next week.

              @jandraka OK the issue is it has multiple textures; 4 I believe. texgen_0,  texgen_1,  texgen_2,  texgen_3,  so you are going to have to do a bit of work to combine all the textures into one single texture. Sorry, I don't have time to do this, but there are many tutorials online; Youtube to help. The trick is 'island packing' UVs in Blender. I hope this helps for now.

                    I don't know if it could help? I have open the file in Cheetah3d and export it as a 3ds File. Then open it in different software with following results:

                    I also export from Meshlab in 3ds and import in Isadora. I cannot saw the Model. The screen remain black.

                    Best regards,

                      Hi,

                      I have had a quick look at your OBJ file. The problem is not the texture but your original mesh. The issue can be fixed by cleaning up the mesh in Blender. I used Blender: Edit Mode: Mesh>Clean up>Decimate Geometry to fix the mesh before exporting it as a .3ds file into Isadora. The following screen grab from the Isadora stage shows the model on the left exported as .3ds before clean up and to the right after clean up.


                      Here are the Blender manual pages for Mesh Cleanup: https://docs.blender.org/manual/en/latest/modeling/meshes/editing/mesh/cleanup.html

                      Best Wishes,

                      Russell

                        Hi, 

                        Thank you very much for your contribution and your time. Really is the way to solve it. I understand that there will be a limitation on the number of vertices or faces that Izzy admits.
                        Best regards.

                          @bonemap that's so weird. I did that time and time again. I could not see those solid white areas in blender at all. How bizarre?!

                            Hi Graham,

                            In my opinion the issue is with Isadora being unable to interpret the anomalies in the mesh and therefore producing the error in rendering the model and texture. Blender compensates for the anomaly and therefore corrects the error in the mesh automatically. In other words the error in the mesh can be detected in Isadora when looking at the wireframe of the model. However it looks ‘normal’ on Blender and many other 3D software that interpret the mesh differently to Isadora.

                            Best wishes

                            Russell
