I have the newest 7.2 installed and even did a clean install. Just curious if SH3D has memory usage limits and/or file size limits? Still get that issue where I can load a large complex 233mb fie but can't do save-as or normal furniture file import without using drag and drop instead. I know building my home 3D model is not optimized like a pro (had someone here look at it) but the save-as not working (ignores me clicking on the menu option) is my big issue. Maybe if I combine multiple custom structures like stair steps into single models might help or do i have to dumb down the detail? My PC has 32gb RAM and an i7- 12700kf 3.6ghz CPU and AMD Radeon RX 6950 XT GPU and NVMe SSD drives. Maybe something to ponder for a future 7.3 version...
