I have two pieces of geometry that I want to join for a modular building this is my geometry without any bevel (the shaded black geometry)
And this is with the bevel
I know what the culprit is but have no idea how to fix it without making incompatible modular parts It's due to where the geometry is connecting
Though I have added a real bevel with a 90 degree lip to stop beveling rather than shading and I have the same issue, but only on the overlapping part shown here for reference and here with the real bevel
In this case it can also join to itself like so
Any ideas on what I can do to prevent this?
