Gamers diving into the world of modding Deus Ex: GMDX v9 have hit a snag recently. As of June 13, 2025, many report issues loading maps in Unreal Editor 1 and 2, raising frustration in the community. Users are asking for solutions as they encounter repeated error messages regarding missing classes.

Context of the Issue

The ongoing challenge appears tied to the proper setup of files and paths. Modders aim to modify Deus Ex, but errors such as "Can't find Class in file" block their progress.

Community Response

Reports from various users indicate a few common solutions:

  • Ensure the correct DeusEx.u file is being utilized.

  • Verify that paths and packages are set up properly.

  • Follow comprehensive guides available for editing, especially for GMDX AE, which some believe is more user-friendly than v9.

"It seems like the setup is critical. Double-check your folders!" - A concerned modder's advice.

However, not all users are finding help, with one stating, "I tried to follow the guide but hit a crash when loading HDTP models." Despite the setbacks, a few users remain optimistic about the potential for detailed modding once these errors are cleared.

User Recommendations

Some community members have pointed out existing resources, urging those facing trouble to seek out the latest guides.
