Treez

This is a step by step tutorial that will teach you how to create a 3D TREE model for use in Trainz. This method uses PlantFactory (free software) to create the 3D tree model but you could use Blender or any other 3D modelling software in it's place. The principles are the same.

Software Requirements

Before you start you will need:

A copy of Trainz. Currently this is in development so in order to test this new foliage system you must be part of the BETA - JOIN.

A copy of PlantFactory 2024. Click the Download button on that page, agree to the EULA and the next page the software should show for download.

You need a set of textures (Bark and Leaves at a minimum) for your trees. These can be created from scratch using the likes of Photoshop (paid) or GIMP (free). You can look to source them from many different websites including Adobe Substance Library or other stock places. There are many other places you can purchase tree stock as a base or to get ideas to build from including CGTrader, TurboSquid and more.

PlantFactory

Examples

A good place to start is with one of our PlantFactory templates. This can speed up your development a lot, especially if you are new to PlantFactory.

PlantFactory Tutorial

Once the software starts up and you've either loaded one of the templates above or you've started a new tree from scratch, if you are new to PlantFactory, you will want to read the "PlantFactory — Reference Manual" (specifically 'Section 5 - Modifying Plants: Using Parameters') which can be accessed by clicking on the Main Menu -> Help -> Reference Manual. This manual explains everything you need to know about the software. It is definitely worth the read.

For those that want to come back to the manual later, here is a video breakdown on a very raw PlantFactory / Trainz explanation you can get started with.
