Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Imported FBX uassets file size are 2 times larger in 4.20 than in 4.19

Greetings.

Models imported into UE 4.20 from an FBX files have file size almost 2 times bigger than they do in UE 4.19 and UE 4.20 takes more time importing the models. I checked all the import settings, they match. And tried different import settings in 4.20. Nothing affected the file size of uassets. Also checked Engine Preferences. They are the same as in 4.19.

Where else can I look to solve this issue?

Thank you.

Product Version: UE 4.20

This problem got even bigger in 4.21.1

Original FBX file is 22,472 KB

Imported into 4.20.3 it was around 50,000 KB

Importing the original into 4.21.1 it becomes 206,772 KB

Almost 10 times the size! Ouch.

I can't help you, why this happens, maybe someone can. But: if it is exactly two times bigger, just halfe the import scale? To check the size you could overlap it with a box brush in editor and try to match it. When you import a window appears. And there:

Thanks for the reply, I appreciate it. But my problem is that the file size of uassets in megabytes, the space occupied by them on my hard drive, is almost 2 times bigger in UE 4.20. So i have to use 4.19 to import my models and then migrate them to my 4.20 project. FBX model that I import in 4.19 is 9MB as uasset but in 4.20 the same model (same file) with the same settings is 18MB as uasset.

Would be great if someone can check this and confirm if this is the engine problem or on my side.
