I have run into a problem and am unsure as to its uniqueness but it’s been a problem for me all the same. I am in the process of importing a large and complex FBX model with thousands of individual parts. 1.46GB with 18,482 parts to be exact. Normally, even while using 32G of RAM, a RTX 3090, and a ryzen 5800x UE5 will crash halfway through trying to import that large of a file. Which makes sense. What doesn’t make sense is that this is only the case when trying to import by using the ‘import button’ that’s featured along the content browser tab. But when using ‘File>Import Into Scene’ from the top toolbar it works just fine in handling the large file and even gets specific by including a progress bar that tells you which meshes out of the total it’s currently on. It may take awhile but it gets it done and works great. But this leads me to two problems that don’t appear to be too much of a struggle to fix.
- The second method of going through ‘import into scene’ rather than the dedicated import button does NOT contain the option to convert meshes to nanite beforehand via a dialog box option. While the content browser import button method does. Both methods should have this option.
I was able to import all 18,482 individual meshes successfully. But because of the lack of the first feature pointed out above I have to resort to splitting up the import process as the nanite conversion through the editor always crashes. I’m okay with this. However when I went to select a fraction of the meshes to import I find that I’m only able to make selections individually. I am unsure how many people know this in general but it is pretty common knowledge that when trying to make a large selection of items (but not all) within Windows File Explorer you click your first pick then hold “Ctrl+Shift” and all of the items between your 1st and 2nd pick are selected without doing anything to the other items. Here you only have the option to either select all/none/individual. Meaning if I were only attempting to select half of the meshes from the FBX file to import so as to keep the editor from crashing I would have no choice but to individually click 9,241 meshes. Twice.
- Let us select multiple items within a menu using the standard “Ctrl+Shift” feature that’s been around forever.
