We've already discussed this on Discord but I just wanted to add the info here for others. The free version isn't limited, but it can happen that multiple materials get merged into one if they are redundant. This behavior can be disabled in BBMOD GUI by unchecking the "optimize materials" checkbox under the import settings.Just downloaded BBMOD GUI free from the website. Is the free version limited by the numbers of materials from the model? Imported 2 models with some materials but only one appears in the tool.
