Sprites after compiling not visible

When I load a Map Enitiy in a new Level, the sprites after compiling not visible. I can see them in the WED. The sprites are in the theme folder as the compiling level.
How can help?

Bye Renato

Your sprites are most likely .dds or .tga files and have an alpha channel. Edit or remove the alpha channel. Also check if the actions assigned to the sprites are making the invisible.

When I create, compiling and run the Enity it's ok. The sprites are visible but when I load this enity in a new level the sprites not there!!! My sprites are .bmp files.

When you make a map entity, only the level geometry is saved as that entity.

You'll have to put in models and sprites in by hand after placing the map entity.

Thanks, I have understand!
