Scaling a spline node too large can hang entire PC

A couple of times I’ve accidentally scaled a spline node to be huge, causing the spline to extend miles along its tangent.

This causes my PC to lock up.

My guess would be that there’s no safety check being done when either drawing or performing some other iterative calculation on the spline which in this case extends hundreds of thousands of units.

The thing that causes the node to scale huge in the first place is that when it’s scaled tiny, the widget becomes very sensitive so will scale huge with a very small mouse movement.

Hi SIGage,

Thank you for the report. I was able to reproduce this on our end and I’ve created JIRA UE-23338. Our developers will be investigating the issue further and we will post back here with additional questions as we have them.
