More Rules

RULE 4

Do not use Double Sided Mesh.

I use to use them but I stopped due to the way Trainz renders them, the color dose not match with single sided. You can not use the same texture on a single and a double sided mesh. When you use a double sided mesh you double the number of vertexes.

RULE 5

Only use dependencies that are built-in or on the DLS.

This avoids the Emails and Post of  "Where can I find KUID: XYZ...." and a missing dependence can make your content unusable.

RULE 6

Use scripts carefully.

If you do not know how to program be very careful with scripts, a lot of them require you to edit them before you can use them. A new update to Trainz can make a script have an error that is very hard to fix.
