Do the following for an optimized approach, this is a way to skip the Paragon Material’s entirely. This can be worked out to a satisfying degree without much trouble.
- Open your 5.3 project copy the meshes and skeleton via Explorer to your fresh 5.4 project - inside a root folder called Paragon or to /Characters/Paragon
For each material do the following
- Migrate or copy by Explorer the textures to your project, into /ParagonFolder/CharacterName/Textures
- Create new MaterialInstances, use for the Parent Material the Engine Material M_GLTF_Default
- Past in the copied textures and assign the Materials to the characters.
