====== Invisible Objects ======

===== Symptom =====

Player cannot see:

* Window Portrait Paintings
* Drake Spirits (currently only on Northlands and Plains maps)
* Light pillars emitted by the main altars at Moor's Rest

This issue only occurs with the modern renderer, which is the default render setting.  See Settings, Graphics tab, Renderer.


===== Fix =====

1. Close all running copies of Wurm Unlimited.  You must do this because the setting you need to change is grayed out in settings when the game is running.
2. Load the launcher, click the gear icon which opens **Settings**.  Go to the **Compatibility** tab and set **FBO** (Frame Buffer Object) to **Extension**.  Save.
3. All done. Connect to Mythmoor.

If setting **FBO** to **Extension** does not work, some players also recommend setting **VBO** (Vertex Buffer Object) to **Extension**, or leaving **FBO** on **Core** while setting **VBO** to **Extension**.

If this does not fix the issue, you will need to change to Legacy renderer instead of Modern in the Graphics tab.

===== Cause =====

Google AI:

//Frame Buffer Objects (FBOs) can make objects invisible due to rendering to an off-screen texture rather than the screen, improper depth buffer setup, or state changes (like blending or clearing) that differ from the default framebuffer. Common causes include incomplete FBO setup, incorrect coordinate mapping during post-processing, or missing depth testing in the FBO context.//
