Hey Agent Smith, how the heck are ya? Well, I don't think they are particular about 'which' format...and we need someone who can convert the 3dmf's for the buildings. That person I guess would upload to GB and then they would be available to us. 'I' am only the one who invited them to come visit the forum and Bryce galleries, I can't import .3dmf's and export them as anything, don't have the software, but I remember someone offering to do this, it was madmax_5, ttops, roch222 or someone offered, you'd need to check the thread...I'll look it up.
