I give up! Can't find the problem

Unity Engine

Has anybody ever run into this?

  1. I create two models (left arrow and right arrow) in Cheetah3d.
  2. I drop them in to a arbitrary my Unity assets.
  3. The import settings of both are exactly the same.
  4. I create an empty GameObject to hold the two arrows. and drag them in to the empty GameObject so that they are children of it.
  5. They become automatically become prefabs.
    6.The settings of both prefabs (except for X position) are exactly the same.

I play the scene and both prefabs can be seen.

BUT…

If I build and run for Mac, iOS, Web ONLY the left arrow can be seen.

I’ve been trying to fix this stupid little problem for three days now and CAN NOT figure it out. I tried reimporting. to Unity. Rexporting from Cheetah3D. Nothing helps.

Could you provide a small repro project that we could download and look at? Maybe we can find the problem.

Thanks for the offer Dustin. I’m going to spend another hour of so on it and if I don’t solve it by then I’ll take you up on your offer. Thanks again.

only thing I can think without seeing is that it’s just positioned off-camera for some reason.

I finally fixed it by redoing everything in Cheetah 3d. I made a unique right arrow and didn’t duplicate the left arrow and filp it 180 in z axis to get a right arrow. That was messing with the normals, even though i tried flipping the right arrow normal both ways it didn’t help. Well, I learned what NOT to do when designing models. A hard 3-day lesson that I won’t forget (hopefully).
