Which engine are you using for your tour?

Common game\3D engine considerations:

- Are your textures square powers of two? (ie. 2x2, 4x4, 8x8x... 256x256, 512x512, etc.) Many game engines only support or only perform optimally with square-powers-of-two for textures.

- Is your picture completely flat? If so, how far is it from the wall? It could be disappearing due to z-fighting. Fixes: Move it further from the wall, or apply a z-bias. (Not all engines support z-bias, but in those that do, that generally fixes it even if the surfaces are right on top of each other.)

- What export format are you using? Some file formats may be merging the model. Many engines, like AC3D itself, can only do one texture per mesh. You may need to choose a file format that supports a hierarchy. Otherwise, many engines will allow you to pull in each piece as a separate file.
