oCam Advanced Settings - Mouse Cursor Effects - Highlight Effects
Click Tools - Options on the oCam main menu, then open the Effects category to check the Highlight Effect settings.

The Highlight Effect is used to help viewers immediately recognize the current position of the mouse cursor while watching a video.
The options are described below.
Color
- This is the color applied to the highlight effect. It is set to yellow by default.
Size
- When the highlight effect is enabled, a semi-transparent circle is drawn around the mouse cursor. This option sets the size of that circle. It is set to 90 by default.
Soft Edge
- The higher this value becomes, the softer the edge of the circle appears.

Opacity
- The lower this value is, the more transparent the circle becomes.
Preview
- Lets you preview the mouse effect you have configured.
If the opacity value is set too high, the highlight effect may cover the part of the screen where the mouse is located. For that reason, it is best to use an appropriate opacity setting.

What to Do If an Error Occurs When Running the oCam Installer
When installing or running oCam, you may see an error message like the one below:
"Access violation at address XXXXX in module 'oCamXXXX.exe'. Write of address 00401000"
This error usually occurs when an anti-cheat program such as GameGuard is running. GameGuard uses system resources exclusively to protect the game, and this can interfere with the installation or execution of oCam. To resolve this issue, follow the steps below:
1. Completely close the game that is currently running. When the game closes, GameGuard will also close.
2. To make sure both the game and GameGuard have fully closed, open Task Manager (Ctrl + Shift + Esc) and check whether any related processes, such as GameGuard processes, are still running. If any remain, end those processes manually.
3. After GameGuard has closed, try installing or running oCam again.
By following the steps above, you can resolve the conflict caused by GameGuard and install or run oCam normally. If the problem continues, restart your computer and try installing oCam again without launching the game.
