A Blender file named my_rock_blender320_final.blend.Three PBR textures and their texture description files:.One very high polygon mesh used only to bake a normal map and a much smaller mesh that will be the first LOD level (LOD 0). A Blender named my_rock_blender320_start.blend.Project filesĪ project file File:Blender320-project.zip is provided in zip format. The first two steps have been done for you. During import Trainz will create Trainzmesh mesh file for each FBX file. Add model textures and texture definition files so Trainz knows how to use those textures.Create a config.txt file that identifies your model, its type, a mesh definition, and a description including an image (thumbnail) of the model.Create additional lower polygon meshes to be used as Level of Detail (LOD) meshes.Create and apply a Trainz material including textures.Create a UV map for mapping mesh polygons to a texture.8 Additional tutorial and Blender help resources.7 FBX to Trainzmesh Conversion Warnings and Errors.3.6.2 FBX conversion to Trainzmesh format.3.4 Task 2 - Create lower poly LOD versions.3 Adding the Material, creating LOD meshes, and Exporting.Save the unwrapped parts as a picture and edit it in your favorite painting program like Photoshop. Depending on your model, you will need to put some seams in order to get a nice unwrap.

Select the object (let’s say the roof) and go into Edit Mode and UV Unwrap to get the single unwrapped texture. This won’t be the house of your dream, but just a simple grungy 3D house.Īs you will see our house is composed by two objects: the roof (I’ve simplified it) and the building part that will contain windows and a door. Step 1: Open Blender and build a simple 3D model

Good knowledge of UV Unwrap and modeling with Blender, but don’t panic you will be able to download the final textured files. Unity 3D 3.5 (will also work on 3.4.2) ( ).You will need to download following software to be able to realize this tutorial:

Yes with textures… The problem is that the workflow is not very clear and often textures are missing what is pretty annoying because once imported in Unity 3D you will need to assign them manually over the Material options… it’s a real pain but fortunately there is a nice solution… But that’s not the point of our discussion 😉 There is a topic that comes very often in forums concerning the export/import of textures in Unity 3D: how to export 3D objects or geometry made with Blender (up to 2.5) in Unity with textures. Believe me or not Unity 3D will be the next hype in the indie game industry and once you have discovered this tool and exported your 3D scenes to your iPhone, Android or even Flash (thanks to the new Molehill support) you will understand why.
