FBX Scene import broken

I’m having an issue with full scene FBX import. Who do I send these test files to?

Hi Duke,

You can attach the file here in a .zip or send privately via the forums to my user account.

When you’re using the full-scene importer have you adjusted any additional settings or just used the default settings?

Can you please make sure to include the FBX and the Source File as well.

Thank you.

Hi Tim,

I have a performance issue with the scene importer.

With a small scene (1800+ meshes total (unique+instances), just -+100 unique), I’m running at 20-50 FPS. If I import it myself, which takes more time of course, I’m running at 100-120 FPS. Same geometry, no strange shader. Aiming for VR, so <90FPS is an issue.

The FBX is properly imported, just running too slow.

Thanks for any help/trick you could find.

Hi Duke,

Checking this in our internal build of 4.13 this issue appears to have already been addressed. It was also something that didn’t reproduce on my assets or test scenes that I have to work with. I do have a workaround that will help though to get your squared away until this fix is released in the next major release.

So, what was happening here was that it looks like when the static meshes were added to a blueprint asset (default setting) they were being offset from each other in their location.This wouldn’t happen if you chose either of the other two options though.

As for the workaround, you can open the BP asset and select all the static mesh components in the list. Then in the details panel on the right side you can click the Yellow Arrow next to the Location button and this will bring the pieces back together. This process will take a few minutes or more depending on your system specs. Largely the wait is due to having so many pieces (~800) that it has to go through and reset this location for.

If you don’t actually need these in the BP then just importing them without using the option to put them into a BP under the Heirarchy Type in the Importer will look correct as well. Then you can just select all these and use the Group Actors option from the right-click context menu to have this whole piece selected but remain separate actors.

I hope this helps and thanks for taking the time to report the issue.
