Good day to all!
The Bug: Whenever I try to merge a couple of modular static mesh actors from my scene, with the Merge Actors pop up menu, using the third option (Harvest geometry from selected actors and merge them into an actor with multiple instanced static mesh components), then whenever the static mesh actors are rotated, a small gap appears in between them. I tested this also on the basic cube instead of my own models, and the same thing happened, I also tried doing this in 4.27, but the bug is also present there.
My Question: Has anyone come across this before, and have you found a solution?
I also tried the other merge options, and they do work, however they make a whole new model, which would not work for my game as that would increase the size of the game quite a lot (as I’m using it to merge a lot of modular buildings), while merging actors into an actor with multiple instanced static meshes seems to work just as well, performance wise, and is even somewhat customizable after the merge.
It would be very beneficial for everyone I imagine if we could get it to work without making these small, but noticeable gaps, between our modular meshes.
I hope we can find a solution for this, or get the kind folks over at epic to look at it,
