Animation Tools

If your project requires movement, you’ll need robust animation features:

• Keyframe Animation: Setting key poses at specific points in time, with the software interpolating the frames in between.
• Rigging: Creating a “skeleton” (rig) for a 3D model, especially characters, to control its movement and deformation.
• Skinning: Binding the mesh to the rig so it deforms realistically during animation.
• Simulation: Tools for simulating physics (e.g., cloth, fluid, particles) to add realism.

Texturing and Shading

Adding color, detail, and surface properties to your models:

• UV Mapping: Unwrapping your 3D model’s surface onto a 2D plane so textures can be applied.
• Material Editors: Tools to define the appearance of surfaces (color, reflectivity, transparency, bump, normal maps).
• Procedural Texturing: Generating textures algorithmically, often avoiding the need for manual UV mapping for certain effects.
• PBR (Physically Based Rendering) Workflow: An industry-standard approach to creating realistic materials that behave consistently under various lighting conditions.

File Format Compatibility and Interoperability

Can the software open and export the file formats you need? This is crucial for collaborative workflows or importing assets from other programs. Common formats include OBJ, FBX, STL, DAE, GLTF, and native CAD formats.
