No AO whatsoever... Could be this, but it's all white, I think. I've fetched some ibl-settings for the jsons via a slow-motion mod...
I don't think a completely white alpha channel in the albedo would cause the textures to be too dark. According to Studio 397, the alpha should be white except the areas that are carbon fibre for some reason. Which IBL shader are you using, carbody or standard? If its the carbody shader there is a setting for each region which controls the lacquer colour. If this is not set as 1,1,1 (white) it will tint the colour, which may be the issue. With the IBL standard shader there is a setting called AlbedoTint which would have a similar affect. Could it be the diffuseColour, ambientColour or emissiveColour settings?
Does anyone know how to generate the needed maps for the IBL tyreshader? As i have had struggles on creating the said maps myself and i have littleidea on how to create them myself?
