This is a pack that will help you create a believable sewage system that looks similar to the sewage system found in London, England.The Asset zoo Scene and Example map scene are compatible with HDRP. SplineMesh is not neccesary but is perfect for bending meshes.This pack contains a variety of meshes, prefabs, materials, textures, shader graphs and maps.Demo video showing the Realtime EffectsThe main meshes (like the tunnels themselves) have been vertex painted with different colours to be able to paint different materials onto the meshes. On the tunnels this is the legend for vertex colour identification:- Red: Black rotted bricks- Green: Yellow stained bricks- Blue: White fatburg covered bricks- Black: Default bricksSix shader graphs are included for different materials. A document is included to help you better understand our pack.Meshes have been created in a way best to work either on their own or with the help of the SplineMesh tool.Features include:-1 Door mesh-1 Ladder mesh-1 Metal Frame mesh-1 Railing mesh-1 Manhole mesh-14 Tunnel meshes (not including flipped pieces)-2 Vertical ladder tunnel meshes-2 Wall light meshes-1 lens flare-8 Shader Graph-1 Asset zoo scene-1 Example sceneNumber of meshes: 65Number of prefabs: 68LODs: Yes (on all prop meshes, not the tunnels)Number of Materials and Material Variant: 23Number of Textures: 110Texture Resolutions: 4096x4096, 4096x2048, 2048x2048, PBR
