Why does my orthogonal Camera3D clip objects nearby?

Default Near = 0.05 is fine for perspective but ortho compresses depth differently; tiny near values cause aggressive clipping. Set Near to a negative or large positive depending on your scene depth axis.

What's the relationship between Size and clipping?

Size is the orthogonal viewing volume's dimensions; Near/Far is the depth slice. They're independent. Set Size to camera width, Near/Far to enclose the entire scene depth.

Move camera back as a workaround?

Works but defeats ortho's purpose (zero perspective). Better: tune Near/Far range. For 2D-on-3D scenes, Near = -100, Far = 100 is common.

Fix: Godot Orthogonal Camera3D Clips Near Objects

Quick answer: Camera3D in Orthogonal mode: Near = -100, Far = 100 (or your scene depth). Size = view width.

Iso camera. Tile next to camera disappears. Default Near 0.05 is too tight for orthogonal projection that views from a fixed position.

The Fix

Camera3D inspector:
  Projection:    Orthogonal
  Size:          10      # width of view in world units
  Near:          -100   # or 0.1 with Far at 1000
  Far:           100

Negative Near is legal for ortho cameras and effectively places the near plane behind the camera origin, allowing geometry around the camera to render.

Verifying

Move geometry around the camera position. Nothing clips out of view due to depth. Far values clip beyond the back plane.

“Generous Near/Far. Ortho doesn’t care about distance.”
