-Export options will only be avaliable when you have an object active in the viewport. This is written 100% in Python which means the export is painfully slow, be patient! Collmesh export with ~4k tris can take up to 20 minutes, trying to export more complex stuff will be a suicide.

 - Inside the `Shader Editor`, assign texture files to the desired texture map types. There should be be 7 `Image Texture` nodes, each corresponding to Base, Detail, Dirt, Crack, Detail Normal, Crack Normal. The last one (SpecularLUT) can be ignored. Detail, Dirt, Crack and their normal maps are optional (can be removed or left unset). There should also be 5 `UV Map` nodes (linked to their corresponding image texture nodes), assign UV layers to them as described below.
 - Each LOD's mesh must have assigned a minimum of 1 and a maximum of 5 UV layers and each UV layer must be called `UV<index>`, where each one corresponds to the following texture maps: UV0 = Base, UV1 = Detail, UV2 = Dirt, UV3 (or UV2 if Dirt layer is not present) = Crack and the last one (always UV4) is the Lightmap UV, when Lightmap UV is not present it will be generated.
 - Setting material's Blend Mode to `Alpha Blend` or `Alpha Clip` will export the material with BF2's `Alpha Blend` (not fully supported yet) or `Alpha Test` transparency modes respectively.
