Lightmap used for blend

Hi! I'm using Ofusion for export my scene from 3ds max.
In a first time all look good, but now some object use the alphachannel of a lightmap for the trasparency.
I've looked the .material file, but no material mades from Ofusion use command like "blend".
Thank for the attention!
