Perfumery for interior visualization in a blender and ue4(I did not try other engines).To avoid some misunderstandings - without trademarks of other manufacturers for your projects.The collection was separated into 7 parts with unwrapping.The model also contains the vertex color for pbr material (color, roughness, metalness), unfortunately, not everything can be imported into the game engine, therefore parts of the collection of roughness and metallicity were connected in one color (RGB), you can split into components: blue channel - roughness, green - metalness content and use of textures in this archive (2 pieces of 128 pixels each) (they were also joined in one color of RGB). For lightmass, an additional uv channel has been created.The minimum resolution for lightmass is 128 for each part.In general, I tried to create an optimized collection - geometry / texture(and their minimum number or lack thereof).
