Italian House Set, which is designed for the game Trainz Simulator (TRS) with support for PBR materials. This project is created gradually. For some models, both winter mode and night mode are created. This can be very demanding on hard disk space for some models, since its installation values ​​are large. The model is then compressed into a cdp file. The highest texture resolution is 2024 px, the smallest with visible texture is 512px. The best is 1024px as a compromise.
