Ouch! The following article, Screen space ambient occlusion, mentions a feature exclusive to certain versions of the client. Specifically: This feature was added in 2011.

Also known as ambient shadows, this feature was added in 2011.

How to enable

If the feature is not enabled automatically, then according to Gemlocker, these are the steps to manually enable the feature:

1. Set graphics mode to Direct3D. The Automatic setting should also work. If the chat button in the top left is wide, then the client is running in Direct3D.
2. Set antialiasing to Off. The Automatic setting should also work.
3. Set quality level to 21.

System requirements

Also according to Gemlocker, there are specific system requirements in order for the feature to be automatically enabled. These may also prevent the feature from being manually enabled and some are undocumented.

These include:

• ROBLOX quality level is at least 14
• Have a certain amount of video memory
• Support two or more rendering buffers

How to check your system

1. Open a place file in the client.
2. Check the log file that ends in "gfx_d3d.txt"
3. Look for "RBX vidMemSize", which needs to be at least a certain amount.
4. Look for "Multiple Render Targets", which needs to be 2 or more.
