Door Fix - Project Viewpoint

Project Viewpoint Door Fix is a Java-based compatibility patch for Project Zomboid that fixes visual problems with doors when using Project Viewpoint.

The modification improves how doors are rendered in the 3D environment, correcting lighting calculations, texture mapping and the appearance of curtains and sheets.

It focuses entirely on visual improvements rather than introducing new gameplay mechanics.

Improved 3D Door Lighting

One of the main problems addressed by the patch is incorrect lighting on doors.

Previously, some doors could appear completely white or black because their lighting was calculated using the game's original isometric system.

The addon changes this behavior by calculating door lighting in 3D.

As a result, doors respond more consistently to the lighting conditions of the surrounding environment.

Fixed Door Textures

The patch also corrects several texture-related issues.

Main improvements include:

• 3D lighting - Doors use lighting calculations appropriate for Project Viewpoint.
• Correct texture mapping - Door textures are remapped to display properly.
• Accurate door states - Closed doors no longer incorrectly appear open.
• No unwanted 2D sprites - Prevents doors from reverting to their original flat appearance.
• Fixed sheets - Sheets display correctly on both open and closed doors.

These corrections make doors look more consistent with other objects rendered in the 3D environment.

Sheets and Door States

The modification improves the rendering of sheets attached to doors.

Sheets should now appear correctly regardless of whether the door is open or closed.

This helps eliminate visual inconsistencies when exploring buildings or using doors covered with sheets.

Requirements and Compatibility

The source code is included, allowing the Project Viewpoint developer to review or incorporate the fixes into the main project.

Specific Build 42 versions and multiplayer compatibility are not stated in the original description.
