What is Model Scale and Why It Matters for Rigging Model scale refers to the size of a 3D model relative to the default grid in Blender’s scene. It is a crucial consideration when preparing models for automatic rigging because inconsistent scales can cause the armature, bones, and weights to generate incorrectly. Setting an appropriate…
Identifying Non-Manifold Geometry Non-manifold geometry in models used for armature-based animation can cause issues like texture distortions or animation artifacts. Identifying non-manifold geometry early in the 3D asset creation pipeline can save time and effort. Symptoms that may indicate non-manifold geometry: Strange distortions in textures mapped to the model Animation issues like vertices detaching from…
Troubleshooting Failed Automatic Bone Weighting When rigging character models in Blender using the automatic weight painting tools, poor results can often occur. Vertex groups may be assigned to the wrong bones, influences may overlap excessively, and deformations can appear broken or twisted. By examining the issues visually, artists can determine the needed corrections in weighting,…
What are Clipping Planes and Why They Matter Clipping planes define the boundaries of the rendered view volume in Blender by clipping away geometry outside this region. The clipping planes consist of the near and far clip distances which specify how close and how far geometry is rendered from the camera viewpoint before being clipped….
Understanding Clipping Planes in Blender Clipping planes in Blender refer to the front and back planes that delimit visible geometry in the 3D viewports and final renders. Any geometry outside these clipping distances is cropped from view. The clipping distances help optimize viewport performance by culling unseen vertices. They also allow artists to crop the…
What is Clipping and Why It Matters Clipping refers to the practice in 3D computer graphics of limiting the rendering of geometry to a certain proximity from the camera. The closest point at which geometry starts being rendered is called the near clipping plane, while the farthest point is called the far clipping plane. Setting…
Improving Viewport Performance by Setting Default Clipping Values The viewport clipping planes in Blender determine the limits of the visible area when viewing and navigating a scene. Setting appropriate default clip start and end values can optimize viewport performance and speed up your workflow. Having clipping planes that are too far apart results in Blender…
