[4.5.1] Crash when importing fbx

Hi Tim,

I also frequently get crashes when importing models. Even in the latest 4.6 release. I’ve always struggled to get UE4 to open models which import fine in other engines.
There seem to be a lot of threads about this here but they just get closed down without a solution.

In fairness I think the models are “broken” to an extent - they’re ones I’ve downloaded from various sources and converted, so they’ve probably got dodgy UVs, missing textures etc. The worst problems also seem to happen on huge models which are a bit ridiculously big.

I think the point is though, the whole editor shouldn’t just crash when it gets a bad import… can’t the importer run in a background thread and catch exceptions and give meaningful error messages rather than just hanging/crashing the editor? That seems like a bug to me.

As I said these same models do import in other engines… A certain well known $1500 engine for example seems to be able to deal with all sorts of errors in the imported data and make sensible decisions to get the asset up and running, without crashing, spewing out errors or having all the materials missing. It would be great if UE4 could do the same rather than the go-to answer being “fix the source material”.

Thanks for looking into it :slight_smile:
