Thanks for taking the time to post this here in AnswerHub!
At the moment I cannot reproduce this on my end and I do have a couple of questions with your workflow that I may not be doing right to cause the crash.
So, here’s what I’ve tried.
I dragged a Lightmass Portal into the scene and then in the details panel used the Blueprint/Add Script option to convert this into a BP. I rebuilt lighting and didn’t have an issue.
Next, since lightmass portals go hand in hand with lightmass importance volumes I added one of these around the default level area and built lighting, still no crash.
I then created a new blank actor BP in the content browser and dragged a Lightmass Portal into the BP from the Modes panel with no other objects in the BP and built lighting, still no crash.
I then created another new blank actor BP with a Static Mesh that I added and then I dragged a Lightmass Portal into that from the Modes panel. I then built lighting, but no crash.
I may just be ignorant with how i would to do this, but how are you converting multiple objects into a BP from the scene. I don’t have that option that I see. If I place two objects (a static mesh and a lightmass portal) in my scene and I select them both I lose option to convert these to a BP in the details panel. Although the only option I see is under the Actor tab where I can select convert to BP, but that will convert them both individually. Still no crash on that part either.
If you wouldn’t mind sharing some information with how you set the convert to BP instant crash up.
Is the crash happening only in your project and in a new default level, or is this happening in a new blank project as well?
Can you also post your DxDiag here? Maybe there is something hardware related I can test in our compat lab that isn’t reproducible on my machine.
Tested more with empty project. Crash seems to be linked to Movable property. When I drag portal to StatMeshActor that mobility is static for some reason portal defaults to Movable. When I build with this setting then it crash. But If I set it to static then it does work. http://pastebin.com/g988wNHw
I’m still not seeing the same results on my end. I’ve made a simple video showing these two methods and the results. Maybe there is something that I’m still missing from your description that I just don’t do.
Me and my colleague have the same crash occurring when trying to “Convert Selected Components to Blueprint Class”.
I kinda wonder why this thread is marked as solved because it isn’t and we have reproduced it on a number of systems.
The way I worked around is by creating a blueprint from the lightmass alone, thereafter add the other parts I need in this blueprint.
This was marked as resolved because the issue could not be reproduced and the user never responded back with the last information I had requested and I cannot reproduce the problem locally using their steps. The fact that the ticket was marked “resolved” does not indicate that there was in fact a resolution, only that the investigation here was either reported, solved by another means, or that it was not reprocible with the information that is currently provided.
If you have any additional steps that you use to make this happen that would be helpful to know since I don’t get the crash on my machine in 4.13.
Also, please post what version you are using, if it’s anything older than 4.13 please try the latest version and see if the issue still occurs for you. Include your Call Stack, Crash Log from the project, and your DXDiag.
Open the level included and select the LightMassPortal + the Spotlight.
Now go to Blueprints in the top menu and click “Convert Selected Components to Blueprint Class”. For me this will crash the engine. If you need more info please let me know !
hmm…I’ve got the crash now. I never used the Blueprint toolbar button to convert. No one even called me out on the attached Test Video above. Which converted fine. Heck, even just using the Lightmass portal by itself will convert fine using the Blueprint toolbar button, however, if you have any actor and a lightmass portal the crash will happen when converting.
