has maintained a dedicated community of enthusiasts who rely on specialized tools to refine and customize their simulation experience. Among these, , a revised version of Paul Gausden’s original utility, stands as a cornerstone for asset modification. Far from being a full-scale 3D modeling suite, SFM25 is a lightweight, purpose-built tool designed for "relatively simple changes" to the intricate shape files that define MSTS locomotives, rolling stock, and scenery. Versatility in Asset Modification
This older version has a unique "Forest Generation" tool missing in later builds. Use this to clone trees across a route automatically.
Let us know in the comments below!
: Allows users to resize models along X, Y, or Z axes and shift their position relative to the pivot point (origin). Texture Mode Tweaks
Route builders: SFM can rotate a flat square polygon to always face the camera (Billboard mode). You modify the TexQuad parameters to enable RotationDelta so your tree lines look 3D from any angle.
: You can shift an object's position relative to its original pivot point. This is vital for fixing minor alignment issues or centering a model.
If your wheels spin too fast relative to the ground, the animation radius is wrong. SFM allows you to edit the wheel_radius variable in the animation section to match the physical .eng file value.
