My Object is invisible !

  • Try to set material opacity value to 1


  • Also make sure your textures are correctly mapped, see Texture slots: on this page
  • Delete your .mesh file then re-export

I have an error when trying to export an object from blender


  • Most of the time, this error popup when you try to export an object that doesn't have any material applied on it
  • If all your objects have material applied and it still popup the error, report it on the forum

There are dark areas all over my object

  • This is because your object has "smoothing", to solve the problem, you can use "Edge Split" Modifier in blender before exporting

Smooth Edge Splitted

sidenote : Modifiers dont need to be applied, you can just enable it, then export your mesh.

warning, Edge split will dramatically increase your vertexes count.

To remove Edge split, in blender, go to Edit Mode, press "W" to popup a menu, then select "Remove Doubles"

  • Yes, export your object with these settings (for example) :

  • Make sure you are on Standard render in the top bar


  • Make sure you textures are correctly mapped, see Texture slots: on this page
