v0.0.8

Fixed

• Three.js semver package version.
• Removed 3 texture sampler units to add room for future features, background map.
• Texture memory leak in BlurredEnvMapGenerator.
• PathtracingSceneGenerator / DynamicPathTracingSceneGenerator: both generators now only include visible geometry in the result.

Added

• GradientEquirectTexture class for generating an equirect background texture with a gradient.
• AttributesTextureArray class for storing multiple vertex attribute buffers in a sampler array to save texture units.

Removed

• Removed FEATURE_GRADIENT_BG define and bgGradientTop, bgGradientBottom uniforms. Use the new GradientEquirectTexture class instead.
• PhysicalPathTracingMaterial: Removed normalAttribute, tangentAttribute, uvAttribute, and colorAttribute uniforms. Use attributesArray to store those parameters, instead.
• MaterialsTexture.setSide function.

Changed

• MaterialsTexture automatically uses the specified material side unless the object is transmissive - in which case double-sided is used.
• Used textures are now reduced to just those with unique sources.
• PhysicalPathTracingMaterial.uniforms.environmentRotation from a Matrix3 to a Matrix4.
• Updated three-mesh-bvh to v0.5.19.
• Rework application of Fresnel based on Joe Shutte's Disney BSDF writeup resulting in improve handling of metalness brightness.
• Use a 1.1 fresnel by default for plastics since it matches GlTF models more exactly.
