In need of a model program

I’ve been looking around the internet for a model program for a couple of 3DS games. I’ve been getting nowhere for most of the day too. I figured this would be the best place where somebody might know about it. I have these assets from using Citra to dump the RomFS. I found one other program called “GAR - ZAR Unpack” that allowed me to get the models and animations. Unfortunately, this is as far as I got since there is almost nothing on the internet about the .CMB and .CSAB formats. That is all… thank you in advance.
