Hi G.M.
-is it ok to provide assets with older Trainzbuilds (i often use 2.9 still)
Older builds are not actively blocked, but it is strongly recommended to use a current trainz-build number. The TCCP system no longer builds for TANE and earlier, and as such using a lower build number would not allow users of TANE or earlier to use the DLC packs.
-is it ok, not to use Blender/PBR, just plain gmax IM/lm?
I dont think it is doing the game good performance wise and I'm 3x as fast making things old school.
The expectation is that most, if not all, of your content built for the DLC pack would use the current technologies for Trainz. So for example, where ever possible the content should use PBR materials. This isn't a hard rule, and it is generally ok for older dependencies to be used where necessary.
There have been a lot of updates to the trainzmesh format compared to the old 'im' format. There were also a lot of updates to the 'im' format in later 3DSMax exporters compared to GMax, including advancements in the handling of materials. This is very important when it comes to performance, as GMax objects are far less likely to make use of texture sharing functions and similar compared to those exported using 3DSMax or Blender using the latest im or FBX exporters.
-if I update an item, how does that work ?
-is it ok to use standard kuid: not kuid2: ?
If the asset is exclusive to a DLC pack, then you would need to submit an update to the DLC pack via the TCCP system. If the asset is a DLS asset, then you can update it through the DLS as you normally would.
The first version of an asset should have it's assetID in the 'kuid' format. Any updates to that asset will need to be in the 'kuid2' format.
-is it ok to include base or built-in items as dependencies (passengers, corona, a horn or engine) ?
This is fine, especially for very common or standard assets, such as passenger assets, and also includes content on the DLS as well. You should ensure not to use content that is exclusive to other DLC packs, unless it is either your own content, or content you have permission to include.
-can sessions for a train be made linked to a route (non payware) on the DLS, example UMR2021 ?
For DLC packs, the DLC pack will need to include all dependencies required by the content in the DLC pack. So if you include a session in the DLC pack, then it will also need to include the route and it's dependencies. This is not recommended, as it can make the DLC pack substantially bigger. Even more so if you make multiple DLC packs that need that route, as the route will then be installed multiple times as part of each DLC pack.
