We’ve set a custom grid snap of 2048, since the “tiles” in our game are 2048x2048 Unreal units.
We’re noticing that when using this feature, there seems to be a very significant floating point error that accumulates over time the more you drag objects around.
Take a look at the screenshot below. I placed the air storage module at the origin and then dragged it along the X axis and back to the origin again. Over time, after dragging it along +X and -X a few times and then back to the origin, the X coordinate of the static mesh actor was listed as:
.000732
.001709
.007568
.124756
This seems like a very significant error, probably too large to be due to floating-point accuracy issues – there seems to be something else going on.
