Oh, then you should be specifically asking about using BSP Factory. I think they may have their own forum you should ask on. I know pretty much nothing about BSP Factory but I wouldn't be surprised (since it does lightmapping) if it behaves exactly the way I described, exporting b3d models with the fullbright parameter on. If so, fullbright will be automatically on when you load the model, without you having to use EntityFX in code.
