Imported Models are invisible in world editor

#1 Several things can cause this: Check the folder of where you saved this model at and see if Torque attempted to make a material for it. If it made a material for it then check it up against a model that does work and not any differences -- on very rare instances Torque could have made an error linking the texture with your model especially if the texture is being used by other models.
Make sure you have your texture in the folder of the model. Make sure you named the material (at least in Blender) exactly the same as the texture file you are using before importing to Torque.

#2 If you open the material editor with the model selected, does it pop in the material?

#3 Thank you for your replies;

@DreamPharaoh: Torque has tried to make a material for it, however it does apply the material to other models in the world.

@David Montgomery-Blake: I can open up the model editor and can see the Material preview, however it doesn't do anything to the model in the world, it is still invisible.

When looking in the shape editor the model is invisible unless I drag the levels slider to 7 (under the details tab in the advanced properties window however it never seems to save the changes.

#4 Is the bounding box large enough to encompass the model? If any part of the model protrudes through the bounding box it will vanish.

I discovered this when I had a model that would disappear when facing certain angles - its hand would poke out when it faced toward the bounds sides (remember that the bounding box is axis aligned and does not rotate).

#5 I thought the details level was for LOD. If this is the case then I believe you will see your model if you are a certain distance away from it in the game world. You might have to be far enough away to where the model would be the size of a crumb. If this happens then it is a LOD issue with the model and needs to be fixed in the models hierarchy before exporting again.
