3ds Max 2024 Live Sync messes the materials applied

I have a headache with live sync D5 3ds max and D5, im making a big project an airport, the problem in every project is the updates of the building itself so it only changes some geometry of the project but when it comes to material applied in D5 and resync it applied double materials, the 3ds max and d5 mixes both materias now i have to redo the materials every update of the project, please make again the message that asked if i want to merge with the D5 applied and not update by itself without any message.

here´s an example in the first update of the project i applied all the materials in D5 correctly, now on the next update of the project it merge the 3ds max and D5 materials now its white and grass and all meshes start to shake or blink with both materiasl applied its very frustating


Did you change the material or change the material name in 3d max?
Also, did you sync a new model to D5 when you synced the model again so that you have two models in your scene.
