The FBX you sent me imported fine into the editor with three animations (included a screenshot below). Can you perhaps post what Import settings you are using with the FBX and let me know if you are using a Launcher or GitHub version of the engine.
the error happens on my pc when during Import the Animation length setting is changed from Exported time to Animation Length
After that change whenever UE4 is opened and the file is being tried to be imported, UE4 puts out the error message even when you use the setting Exported Time instead of animated time.
Worst thing is, even closing the Epic Games Launcher and reopening everything still causes the shader compiler error like it remembers that there was an error.
I encountered this same error too when converting 4.7.6 to 4.10.4. How do you know which asset is causing the crash? Error log doesn’t mention any filename or anything. Otherwise we will have to the ‘elimination technique’ which is cumbersome for large levels…
Make sure to check your logs in your project folder > Saved > Logs. Open the log and scroll down to the very bottom where the crash details are located.
You can find the asset name here that caused the error.
Did you try not importing the asset with the materials and textures? If so, did you still get the crash?
If you have a test asset you can post here and I can see if I can reproduce. Also include your epic/machine id’s and logs for reference. If I can reproduce it’s much easier to get a bug in and see if we can prevent this type of thing from happening.
