When we work on a big project file on 3ds Max and merge so many models from different libraries. Some models can affect our files if it’s not optimized well, or if already there is a hidden track in that models, this can make our 3d Max file bigger and increase save file time. I struggled always with this issue before. Recently I found a script in my folder and I test it on one of my old heavy files, the result was unbelievable. Since that time I use this script with any model before I merge it into my scene. I would like to share with you the Test results before and after using this script.
