Instanced mesh does not snap properly on bluprint

I recently tried to change my blueprint blocks to a instanced mesh since i was adding a bit too much and needed instanced meshes to make the game with a low FPS drop.
but that made it a bit frustrating since I cant make the game rooms just like i had before.

i noticed small gaps between meshes and its making me crazy. I can manually change the location rotation and scale transform, but if i move them, they automaticly change properties. from what i can see, this only happens to me if i do the blueprint with instanced mesh. not static mesh. any thoughts?

I’ve been over this problem for 2 days now, can’t find the solution. maybe someone has any idea of what can i do?

I have snap to grid enable and it seems that even AFTER I put the mesh, it changes transform by itself… is it a bug?

Hi !
I’ve just get the 4.8.1 version of UE, I’ve encountered exactly the same problem, and I’ve gone crazy just like you !!! I didn’t found workaround for this “bug”, and I finally switch back to use StaticMesh Component instead of StaticMeshInstance Component. I 'm very disappointed because everything was perfect with the 4.7 version. I hope we will have an advice about a way to manage this problem.

same here. the thing is what im doing requires too many meshes. I prefer continue doing it AFTER it is resolved

I would assume that at some point you would end up making your own custom meshes for the game so why not just jump into Blender or your 3D modeling software of choice and create your own mesh? Even if it’s just a grey box simple mesh, it should work ok. While this I’m sure isn’t an ideal solution for your current problem it would allow you more flexibility in your design and give you a jump start on your eventual modeling.

that cant be possible since, i’m using random instanced rooms and random instanced items within the rooms.
something that randomly generates walls and doors as you play. as you can understand that would really limit the possibilities…
