Marquee select in cascade curve editor causes crash

I couldn’t find anything on this in a search, but I’m hoping it has been brought up and fixed in 4.1. About 15% of the time I marquee select in the graph editor of cascade, Unreal crashes. Has this been fixed?

Hi VFX,

Can you walk me through what you are attempting to do? What steps are you taking to cause this crash? Further, can you provide the crash log (found in the folder \UnrealProjects\PROJECTNAME\saved\logs\ ) and the dxdiag please? Thank you!

Sure thing . I’ll list out the rough steps. I haven’t narrowed them down 100% and I’m not at my development computer right now or I could try. Same with the logs. It’ll be tomorrow before I can upload them.

  1. Create a new particle emitter
  2. Add a GPU module to the emitter
  3. Graph the Color Over Life module and remove the Alpha Curve from the graph
  4. Show all and then hold Ctrl+Alt and select all the points on the curve
  5. Repeat step 4

Result: Roughly 1/10 times this will crash UE4 for me

My apologies, I still haven’t gotten a chance to upload my logs. I’ll do so when I can.

Hi VFX,

We were able to reproduce this effect and have put in a bug report with this link as well as our findings to be assessed. Have a great day!

Oh, great news! I actually forgot to upload my logs. I’m sorry about that. I’m so glad to hear this though. Excellent work as always!
