Modular Castle & Dungeon (Medieval Stronghold, Dwarven Town)

1. Shaders:

• Top cover shape shaders feature:
• Base: texture shader between multiple materials like marble, rock, clay, and sand so all objects look like built from the same source. It can use UV0,UV2, Planar
• Cover: texture for top cover, vertex color, heightmap blend for example snow, sand. It can use UV0,UV2, Planar
• Shape: Normal and MaskMap C(R) AO (G) H(B) LM(A) textures that hold the shape information of the object. Curvature (R) and AO (G) influence on the material. It's used for heightmap (B) blending between base and cover. Leaks masking (A). It can use UV0, UV2, and Planar.
• Leaks: Texture for leaks mostly uses the same UV as shape. It adds noise, color changes to objects so they do not look generic. It can be colored.
• Wet/Heat: Materials can be heated or become wet via vertex color. Even at runtime. with our L.V.E 2023.
• Shape shaders use AO as an emission mask to avoid adding another texture just for emission.
• The shader contains a large number of sliders to control blending between the base and cover and shape influence.
• With very few textures you can populate the whole world by using these shaders.
• Lava 2023 sample shaders. Pack contains lava river and rock, particle shaders from our L.V.E 2023. If you need more variants visit that pack.
• Decals: Decal shading is only available at URP and HDRP as only these render pipelines support decals. Pack contains dirt, mud, ornaments, and ice decals.
• Particles and VFX: Pack contains fire, smoke, and distortion particles. Distortion at HD and URP needs a unity VFX package from the package manager (at HD RP it's by default inside the project). VFX are much faster particles.
• All shaders support vertex color the basic idea is:
• R: make object wet or heat (checkbox)
• G: cull top cover (snow, sand, 2nd texture)
• B: overlay surface via cover (snow, sand)
• There is also a layered shader for those who want to have a base, base 2, and top cover textures at the same time. it's available at URP and HDRP. It has huge potential.

2. Textures:

Most of them are 4k atlases. A few atlases are not finished, have a space for upcoming details.

• Base Color - Base Color (RGB) Smothness (A)
• MaskMaps MT_AO_H_SM - Metallic (R) Ambient Occlusion (G) Heightmap (B) Smothness (A)
• Emission (A)MaskMaps Emissive MT_AO_H_E - Metallic (R) Ambient Occlusion (G) Heightmap (B)
• Shape: Curvature(R) Ambient occlusion (G) Height(B) Leaks mask(A)
• Normal: Normal maps textures

Assets are atlased and used only a small amount of textures, mostly 4k but you can reduce them for your goals. It's better to have a reducing option than no option to upscale.

3. Scripts:

- Vertex painting tool: You can cover, uncover, heat, and make the surface wet via vertex colors.

- Collider: vertex painting tool (to remove snow from interiors) or just for any other effects

- Mask Generator: You can prepare textures for our shaders for example from Muse.

- Manage Light Visibility: You can optimize lights at big scenes, it culls light, and shadows via distance. It helps to save CPU at a big scene with a big amount of lights. Helpful in real-time lighting.

4. Models and prefabs

A huge amount of models and prefabs contain LODs. The triangle number depends on the object's size and complexity. Prefabs also have re-defined LODs so they work together as one object, to avoid situations when one wall from the building disappears earlier than the whole building.

Models have:

UV0 - for tiled textures base or non-tilled shape.

UV1 - lightmaps

UV2 - shape, leaks uv
