Use OBJ2BLB for your BLB files.
Also, download the version from the tutorial I mentioned in my custom brick thread and use that for .DTS files.
It's not showing up in the list for me, but I don't think that's my exported files. OBJ2BLB should work without any config changes.
.DTS exporter... Not sure.
Anyways, just follow along with my thread, we both want to do the same thing.
