102.3 Hotfix

Bug Fixes

  • Separate MDL functions which require MDL 1.7 to a new core template which will be imported as needed. The main Ue4Function template maintains MDL 1.6 to compatible with older Kit SDK versions (OM-35152)

    • This specifically addresses the issue where Machinima 2021.1 shows red materials with Unreal 102.1 and 102.2 exports

  • Fix a crash by adding error checking for the custom mdl function translator

  • Avoid repeatedly copying template MDL files when exporting materials


  • Add option to decide if exporting preview mesh as well when exporting the animation sequence (disabled by default)

  • Add support for HSLS exp/exp2 to MDL math functions
