# Occlusion Issues and Disappearing Objects
### Occlusion Issues
The most common cause of disappearing objects or performance issues is the overlapping of two or more files.\
To properly solve this issue, you need to remove any **duplicate files**. How do you do that?
### 1. First, go to the **"Original Objects"** folder and locate the file named **"vb\_occl\_01"**.
### 2. Copy its name and return to the **"resources"** folder.
### 3. Use the **File Explorer search** function to search for that filename.
**Once you’ve found the files, check their locations and delete them.**\
\
⚠️ **WARNING:** When deleting ambient occlusion files, there is a chance that other MLOs may stop working properly.\
In that case, please contact us so we can adjust the file to meet your server’s requirements.
If this operation doesn’t solve the issue, it likely means there are **many more duplicated files**.\
It’s recommended to repeat this process for **all files** in the "Original Objects" folder — especially those with the **.ybn** and **.ymap** extensions.
