It shows the mesh in all the other view modes and in the editor but not when playing in standalone. It works in 4.16.3 Blueprint is using the [Add Instance node] with an [instanced static mesh] imputed into Target and just a change in Transform. ---

Hi Andrew, Thank you for the report. I was able to reproduce this behavior, so I’ve created [JIRA UE-48228](https://issues.unrealengine.com/issue/UE-48228). Our developers will be investigating further. Follow that link to monitor the status. -TJ ---

It appears to be fixed, but not yet pushed to the repo. Is the fix small enough to be posted here? ---

I think I may have the same issue after going from 4.14.3 to 4.17, but in c++. I’m using an array of UInstancedStaticMeshComponent to add, update and remove instances via methods like UpdateInstanceTransform. I don’t know why, but when I do a specific action in-game and call UpdateInstanceTransform on a single UInstancedStaticMeshComponent , it seems to remove most of all instances of all UInstancedStaticMeshComponents. The only way I could see this happening is if the instance array and indexes were changed following a RemoveInstance, but I’m not doing that. Also, like in this post, I only see the problem in standalone game mode, not in the editor view. So, that leads me to believe that this is a bug. Could this be related to this blueprint issue? Is there any fix incoming? I updated to 4.17.1, but no luck. Thanks. ---

Hey ItBurn, if you look at the link in Speedy37s post they said it should be fixed in 4.18. ---

When I package my project, I’m still having the issues, but I actually get even more issues that aren’t there in Standalone mode. Now if I create new mesh instances when playing, after a point they start flickering, moving, appearing over other instanced meshes and getting invalid transforms. ![210651-instancemeshglitch.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/e/0/1e0ecff4a12d29f7061b934eb9c1f57922b0b121.png) This is a pretty important problem as I can’t test anything. Reverting to a previous version would be a big headache and 4.18 is really far away. ---

Lol, same problem) But HierarchicalInstancedStaticMesh work fine in Stand Alone ---

Hierarchical does work better for me in Stand Alone, but they still have massive issues when running the packaged project. ---

Yeah, i noticed this too, so, already revert to 4.16. And happy with instances) ---

Hi can you try with 4.17.2 to see if it improve things, and if it’s not fixed, some fixes had to go in 4.18, but i could provide you with CL# or Github# so you fetch directly the changes but it come with greater risk as it’s not QA approved. ---

I just tried 4.17.2 and it didn’t solve the issue in standalone mode. Not only that, but the first time I updated the transform of an instanced static mesh, the editor froze for a good 10 minutes. I hope it’s not going to do that every first run… I didn’t try packaged. edit: The freeze happens regularly, but I can’t figure out what sequence of events brings it. It’s always when I update the transform. ---

I’ve had the same issue in Standalone mode, but the v4.17.2 update seems to have fixed it in my project. Packaged versions are working fine as well. ---

Strange. Are you using blueprints or c++ to create your instanced meshes? Maybe it’s fixed for blueprints and not c++. ---

ItBurn if you use Blueprint is should be fixed, as for C++ and with CreateDefaultSubObject code path, this had to go in 4.18 as it imply interface changes. It should be available quite soon in 4.18. ---

Just tried 4.18. It works! At last.
