Solution: You reverted to a vanilla Tunedata, but you still have modded global.iff files active. The Tunedata is calling for specific skin shaders that the modded Global doesn't have. You must either revert your Global to original or re-mod the Tunedata.

The Original Tunedata.iff acts as the "base paint." Every major mod pack—from the 2024 EuroLeague mod to the historic 1990s Dream Team mods—starts with the question: Do we build on the original tuning, or write a new one?
If you are building a mod, keep the original as your anchor. If you are just trying to play a quick game of Heat vs. Spurs, search your hard drive, find that pristine file, and never let it go.
If you are trying to play a classic roster from 2014 or 2015—perhaps a "2013-2014 Season" roster that wasn't updated for modern modding engines—it is often programmed to work specifically with the original data values. Using a modern, modded tunedata.iff with an old roster can result in bizarre gameplay glitches, super-human shooting percentages, or broken AI logic.
Only use the original Tunedata.iff if you are playing a modded roster from 2013-14 (actual Heat/Spurs era). If you are playing a modern 2024-25 modded roster (Wembanyama, Curry, etc.), this file will break the game. Find a community patch immediately.
