Disappearing Walls?

How come everything is different from blender project view, render view, and BGE view?

Project view the textures are right, but the inside walls are missing?? The outside shows, but it’s wireframe inside the house.

Render view everything is correct.

BGE view, no walls inside again, and the wood texture is changed to the roof material??

In the texface options set all the faces as two-sided, otherwise they’ll only render when the front is seen by the camera as the backface culling for that face is enabled.

Two sided is on in the edit (F9) panel

did you find the solution ? can you help me i have the same problem
im using upbge 0.2.5

This is caused by inverted normals. If you want your walls to be double-sided, disable this material setting.

If rather only keep on side of your wall, toggle this Edit Mode setting.

You can also view normals in legacy Blender versions by enabling this setting while in Edit Mode.
