SC4 Model Tweaker is a tool by Cogeo to directly modify exported SC4Model S3D. The tool can apply geometric transformations—move/offset, scale, rotate, and mirror—consistently across all zooms and rotations. It is ideal for creating overhanging or offset props, fixing orientation or height issues, and aligning modular or diagonal assets. Textures and UV mapping are preserved, and the model’s bounds are updated so changes are accurately reflected in-game.
