Converting from old textures to new PBR

 

The new PBR textures look much better than the old ones but you can only use them in TRS2019 as it has to be a FBX mesh and Trains Build 4.6 to work.

 

You can not just replace the old textures you need the mesh file as you have to change the Material name and export it as FBX.

You may need to re-do the UVmap(s), PBR dose not like overlapping UV's, you have to bake an AO, you could get away with that in the old textures. Also your RBG numbers must be between 50 and 240, not the full 0 to 255.

PBR has 3 textures vs. old 2. Your old color texture needs the Alpha channel removed and all lighting info, that is remove any AO or shadows.

The Normal textures are the same, do not use an Alpha unless you need parallax. You should set Shader Quality to Ultra to turn on parallax.

The config.txt needs a few changes for FBX, namely Trainz Build 4.6 and your mesh name from name.im to name.trainzmesh and add this "mesh-table-lod-transition-distances".

I will be posting a three part how to.
