Model-/MaterialEditor crashes when trying to create a billboard! D:

[shadowZgamerZ]

It's most probably that you did not create .mat or .dds file properly. Same problems happen when opening folder with custom model (penumbra model in my case) that is not converted proprely or at all in LevelEditor! The way I convert: open material editor, open .mat file, change diffuse texture, save as newmaterial.mat or overwrite existing one. I didn not convert billboards. Do they have

.dae and .ent! You dont need .dds for material editor, you can use .jpg/.jpeg also!

If billboards have .dae and .ent try doing this: open .ent of billboard, add mesh .dae, add body, remove collision or make without body and save. Does your error occure in Material Editor, Model Editor or Level Editor? If there is something else problem, give more information about problem.
