KT - Interior Mapping

Interior mapping creates the illusion of depth and inhabited spaces visible through building windows
Through texture projection and UV-based perspective correction in the pixel shader, interiors render with convincing 3D depth and lighting adapted to the urban environment

Features

• Perspective-corrected depth: Maintains proper 3D illusion regardless of camera angle
• Atlas support: Each building can have unique interior appearances
• Room ratio presets: Every atlas is dedicated to rooms with a specific height/width ratio, and the UV projection adapts to these ratios
• Multiple depth layers: Artists can provide additional textures that add depth to the interior (the alternative was parallax on top of the UV projection, which is significantly more expensive)
• Framebuffer mip blending: Windows can get blurry based on their roughness texture
• Urban lighting integration: Naturally adapts to day/night lighting conditions
• Performance optimization: Distance-based quality scaling for optimal performance
