Union operations disappearing although the transparency is set to 0

[TeatedLine06 (ONI)]

You can write your topic however you want, but you need to answer these questions:

1. **What do you want to achieve? I want to know what seems to be the problem

2. **What is the issue? The unions are not there even when the transparency is set to 0
   

   

3. **What solutions have you tried so far? I’ve seen some people talk about unions disappearing temporarily when publishing their game, but not like this…

I’m sorry. I just can’t rap my head around this, that’s why I’m asking for help here. Thx

Oh and if I seperate the union, it gets erased. I put this in scripting help since it might be a bug or something Idk.

This post has been made a ton of times, like a crazy amount. It’s just a problem with how Roblox’s unions function.

This guy gave a small tutorial on how to fix it, you should definitely watch it.

The problem isn’t the collision the problem is the the unions just disappear out of thin air.

The union was visible Before I published the game. But after I published the game, the union disappeared.

How to recover invisible / corrupt unions

Introduction This tutorial will walk you through finding and recovering your unions if they get lost / corrupted / turn invisible. This method relies on trial-and-error, and works best if tried immediately after you’ve lost a union. Background Information When a union is created but before it or its place is saved, it contains child data - information about what it’s made of, stored directly in the place. When the union is saved to Roblox, a new SolidModel asset is created. The union instanc…

Yeah, that same concept of a post has been made so many times.

Do you know why this happens so I can prevent it from happening again though. plz

There are a lot of reasons as to why unions get corrupted.

Possible Reasons:

• Connection Issues
• Bad Studio Session (studio may be acting up at the time of union being created)
• Roblox may be experiencing a high load (possibly due to a lot of players currently playing, data stores, etc)
• Union was too complex and was not detected properly
• Union got “disconnected” from its asset id on the website
  The list goes on and on

My solution:

Don’t use unions.

Why? Because meshes are far more reliable.

Also, your post belongs in #help-and-feedback:building-support like what @crashedthe911 mentioned
