*The interior should be a separate Model. Having it separate enables delayed loading of such models in multiplayer/AI contexts. Such a model is specified as follows in the -set.xml file: | |||
<syntaxhighlight lang="xml"> | |||
<model> | |||
<usage>interior</usage> <!--make sure to have this tag--> | |||
<path>Models/interior-model.xml</path> | |||
</model> | |||
</syntaxhighlight> | |||

*Use power of two dimensions for textures (2<sup>n</sup>, e.g. 256x256, 512x1024). Do not worry if your image would get stretched in the texture, you can fix that with the mapping on the model. | *Use power of two dimensions for textures (2<sup>n</sup>, e.g. 256x256, 512x1024).

<!--== Animation guidelines == | |||
*Keep the number of range animations to a minimum. Load the instruments in a submodel XML file, to avoid having one for each instrument. Testing one range animation is cheaper than 47.--> <!--commented out for now--> | |||
