How a mod is made

Our workflow follows the classic asset pipeline of game development – from reference to release.

Reference: Brunn top station

Reference

It all starts with the real thing: photos, plans, dimensions and data sheets are collected so that proportions and details are right later on.

Wireframe model of a snow generator

Modelling

Triangles become a mesh. We keep a clean polygon budget so the model runs smoothly even in large ski resorts.

Result
Low-poly mesh

3D modelling
Untextured model in the 3D editor

Detail & Rigging

Parts are separated, pivot points set and moving parts prepared for animation – such as flaps, tillers or fans.

Textured Sufag snow generator

UV & Textures

The model gets colour and surface detail, plus LOD levels and collision models for performance and physics.

Integration & Scripting

Export to the game format, configuration and scripts: only the Lua code makes switches, lights and snowmaking usable in the game.

Testing

Our beta testers check every mod in the game for bugs, performance and usability. Any bugs found go back to development.

History

  1. 2013

    Thomas Brandl founds LSBrandi and AMC Modding. The goal: a true-to-life recreation of the Planai in Schladming!

  2. 2014

    The Planai keeps growing, and more and more people join the ambitious project – the only recreation of a real ski resort in Giants Software's Ski Region Simulator. We were happy to welcome Veit and Simon to the team.

  3. 2015

    The first TF10 pack is released, laying the foundation for the later Techno Alpin Pack. LSBrandi Modding's first map, Grosseck, also goes online. Along the way, modders from the well-known Mountain Modding team start supporting Mr Brandl's projects – which is how Sevi, Nick, Tim and Tom joined the team.

  4. 2016

    The Prinoth Everest is released as the second Prinoth snow groomer for SRS, shortly followed by the first freely placeable Gemini snow lance. The Sufag Compact Power Pack brings Sufag snow generators into the game for the first time. After a restructuring of the team, LSBrandi and AMC Modding finally become Alpin 3D Design. Max and Machi greatly boosted our modelling know-how, and our snow guns got self-developed functions for the first time. Next came the largest snowmaking mod pack for SRS to date, the Techno Alpin Pack – and, on the last day of the year, the first beta of the Planai we had started in 2013.

  5. 2017

    Project Brunn with the first Leitner 3S cable car is announced. With the Snow.Manager we also create our first piece of software that runs independently of SRS and makes changing seasons much easier. We also started a project we would never finish: Artificial Snow Control, ASC for short. As a snowmaking management system, this script mod was meant to enable realistic snowmaking through central control, weather, pumping stations and realistic operation of all snow generators – including third-party ones. However, Winter Resort Simulator, the successor to SRS, came out first.

  6. 2018

    We kick off the year with a livestream: 6 years of LSBrandi Modding & Alpin 3D Design. Never before had so many projects been running at once. We released a big update for the Sufag Pack with the Peak and every tower variant. It also included the first spin-off from our ASC: the realistic start-up behaviour of a snow gun. Another map saw the light of day – Edelsee, and with it our first in-house ropeway control system, RWC. Together with Snowman73 we managed to make the Techno Alpin lance pack available for free to everyone at the end of the year.

  7. 2019

    While the scene was abuzz about a newly announced simulation game, we kept working hard on Edelsee, our snow gun control system ASC and our new ropeway control system RWC. Thanks to this, in February we were able to build a Leitner Telemix lift for the first time – with save-game and multiplayer support, built from scratch, of course!

  8. 2020

    This was the year: WRS was out, the modding tools were too, so together with SRTD we released our well-known Sufag Pack from SRS here as well – with the same features, of course. Over the following years it was continually expanded with snow generators from Techno Alpin and Lenco as well as snow groomers from Prinoth, so it was soon renamed A3D SNOW.Management. With almost 25,000 subscribers and 5 stars, it is now the most downloaded mod for Winter Resort Simulator 2. Roby also significantly expanded our Prinoth Pack for SRS.

  9. 2021

    Alongside numerous updates to our SNOW.Management pack, one team took on an update of Grosseck, our map released in 2016. The major investments in expanding the ski resort, once advertised on the map, finally became reality. The map gained a whole new area: the Hochalm. This update will probably remain our last release for Ski Region Simulator – and with it the only use of our own ropeway control system, which we had worked towards for almost 8 years.

  10. 2026

    In the years that followed we kept maintaining A3D SNOW.Management and ported it to WRS Season 2. At the same time we were eagerly waiting for the first modders to bring Leitner Ropeways, the second major ropeway manufacturer from South Tyrol, into the game. When that didn't happen for quite a while, we decided – having represented Leitner in simulations for 10 years by now – to do it for WRS 2 ourselves. Driven by Dominik, Georg and Niklas, two chairlifts from very different model series were created over the years, which we released at the beginning of the year together with our implementation of the LEITCONTROL control system. At the end of 2026, driven by Stefan and Baisi, the expansion with two gondola lifts followed.
