I have recently been working on a virtual reality project built in game studio. The project requires a very human-like model to interact with the player. This model was built in 3ds Max, imported into MED, and then placed in WED as an entity. The model shows up in MED and in WED, but when the level runs, the entity has completely vanished. It doesn't show up partly, or even suddenly and then vanish, it is just not there. Also, I have no actions attached to it, so I can't be moving it dynamically.
There are various things that I have tried: flipping the normals, making sure that the entity is not set as invisible nor set as transparent, texturing in both MED and 3ds Max, and several other things, none of which seem to work. The textures are .bmp files, so I doubt they have any kind of alpha channel.
So, if anyone could help me, I would really appreciate it.

Few things i can think of.

1. The model is too high poly and the engine is having trouble rendering it.

2. You camera is not set to a proper position to view the model.. IE inside the model.

3. After you placed the model you didnt rebuild the level with at least update entitys.

4. An old bug but still may be around. At times wed would append ~something to the end of level names when opening them.

Just look at the top menu bar where it says the name of the level. If you see ~ with anything after it this is likley the cause. Easy soulution is to go to file>save as and overwrite the level, rebuild and try to run again.

Other then this cant think of anything at the moment. Hope one of the above helps.

Thank you for the speedy reply, FeiHongJr.
I ended up setting the skin properties to have alpha = 100 in MED. This made the model appear when I ran the level.
Once again, thanks alot.
