Define the purpose and scope of the walkthrough. Determine the key features, viewpoints, and areas to showcase.
Sketch out the sequence of scenes and camera movements. This helps in visualizing the flow of the animation and ensures coherence.
Create detailed 3D models of the environment, buildings, objects, and characters using software like Blender, Maya, or 3ds Max.
Apply textures and materials to the 3D models to enhance realism. This includes adding colors, patterns, and surface properties like reflections and roughness.
Set up lighting sources within the scene to create ambiance and mood. Adjust the intensity, color, and direction of lights to achieve desired effects.
Animate the movement of objects, characters, and cameras within the scene. This involves keyframing, where key positions and poses are defined to generate smooth motion.
Define the path the virtual camera will follow through the environment. This determines the viewpoint and perspective of the viewer as they navigate through the walkthrough.
Render each frame of the animation sequence using rendering software such as V-Ray, Arnold, or Blender's Cycles. This process may take time depending on the complexity of the scene and desired quality.
Enhance the rendered frames with effects like depth of field, motion blur, and color correction to improve visual quality and realism.
Compile the rendered frames into a coherent sequence using video editing software like Adobe Premiere or Final Cut Pro.
