The “debug” discs to show angular limits are no longer visible with 4.11. E.g. try to set angular swing 1Motion to Limited and change the angle.

Hi SaOk,

This has been reported [here](https://answers.unrealengine.com/questions/404994/no-angular-constraint-visualization-in-physics-con.html) and it is logged as JIRA UE-29503 in our system. Our developers are investigating it.

Cheers,

TJ

For now, the horrible workaround that I’ve found is to go into PhAT\_JointLimitMaterial (Engine Content. Engine\Content\EditorMaterials\PhAT\_JointLimitMaterial.uasset) and change the Blend Mode from Translucent to Opaque. They will show up and be workable, but, you know, opaque. Not a huge deal, and it allows me to keep working.

Everything else that I’ve tried shows the constraint discs black for a second (while shaders build) and then, as soon as they’re done, they disappear.

I know that this is somehow related to the project, as I was able to (with the same executable) see those discs (on the same asset, SK\_Mannequin), but not when trying to view them in my project. Some view setting must be different nowadays. I’ve tried using Reset layout, to no avail.

For now, I’ll have opaque constraint limits.

Posting in both threads
