So I was doing union work in studio and I came across a small issue in which I thought I was capable of fixing. In some ways I am able to fix the issue stopping me but I still wanted to report this surface union bug and I was still hoping if there was a fix for it if not a bug for future purpose. -( I was able to get rid of the surfaces by overlapping two parts on both sides showing the issue but I still believe this is a bug that probably needs to be fixed)
In my an attempt to fix this I removed the wedge block on the left and replaced it with a normal block and overlapped it, then union my part. NOT Once did I touch the right side and now the issue is occurring over to the opposite side as it was fine before.
The issue shown in the image below is usually due to the negated parts being not perfectly aligned.
Be sure to check the position and make sure the negated parts are touching and are perfectly aligned. In addition, make sure their not crossing or overlapping each other.
Thats not the issue I already stated I aligned the parts using a plugin and its very effective if you continue reading you will see in an attempt to fix this I overlapped it then it changed the surface problem to the right side when the right side was untouched by any changes.
I have done this. Before I used the alignment tool I dragged the part onto the other part so it made contact to the surface It did not fix but that still doesn’t answer why the problem occurred on the other side as it was fine before. (The left side was the problem, the right side did what it was suppose to do, when I fixed the left side I NEVER touched the right side yet now the right side is having the same issue while the left side is fixed.)
It occurred after you overlapped the negated part correct? That would be the cause of the problem. The specifics I know not though I do know that the overlapping of negated parts usually have unsavoury effects.
Yeah that is what I am going to do but I still think there is a surface bug I don’t think everyone should have to be apposed to having to overlap parts to fix their issue.
This is a common bug that occurs with CSG V2. I’ve experienced it a couple of times as well. There are a few workarounds for it, such as negating the thin line or overlapping the negated parts which cause the problem by 0.001 studs.
Additionally, you could just create the union in CSG V1 (accessed by setting “Disable CSGV2” to true under the Physics section of Roblox Studio’s settings). However, CSG V1 has several of its own issues, so I wouldn’t do it all the time.
Thank you, I appreciate your response and I hope others seeing this issue can see your response as it has been by far the most helpful answer. I wasn’t sure if it was a bug.
