Uniblocks [HDRP]

• Only for Unity 6+ HDRP; URP and Built-in rendering pipelines are not supported for technical reasons. Hope this will change soon!
• By design Uniblocks can be assembled only into rectangular constructions with straight angles (but corners and windows can be rounded), walls thickness is 0.5m. This fits well for APV lighting (easy to avoid light leaking thanks to walls thickness) and also for reflection probes with rectangular bounds.
• Lightmaps are not officially supported (each uniblock has UVs for lightmapping, but lighmaps looks horrible on modular constructions with clean seamless design so usage of lightmaps can be only last resort measure).
• Performance demands: typical single story house will have more than 1K uniblocks with 3+ materials on each of them = 3K draw calls just for one empty building.
• Learning curve: smooth edges on all blocks and seamless stacking between different blocks types - looks and feels good, but this feature is slightly cursed and requires knowing how to avoid seams/bumps by using few special block types.
• All prefabs containing glass has it as a separate GameObject (easier to make it destructable, if need be).
• Number of Prefabs: 834+ (mostly size variations).
• Number of Materials: 70+, all seamlessly tiled.
• Any tiled material can be applied on any Uniblock - no baked textures (except trees).
• Custom shader for majority of materials: 2 layers of textures, distance-based fade in for 2nd texture layer, triplanar UVs, UVs rotation, differed triplanar seams.
• Primary size of textures is 4K.

Some of the textures are of my own making, some were taken from:
