Medieval Kingdom has been made using modular workflow. That means that every element is created in a way, to easily build different variations and configuration for exterior buildings & maps.

1A. How to use it ?

Just drag all needed elements from prefab folder into the scene and start to craft your buildings. Everything depends on your imagination. Then when you will build your final architecture, you can always maniuplate specific parts & textures of materials to change Colors, AO, Roughness, Dirt etc. This part will be described at the bottom in Materials & Shaders Section.

Prefab Scatter

Use Polybrush or any tool to brush prefabs with randomness to distribiute vegetation as shown on example.

Prefab Placement

Every elements in Medieval Kingdom is made as a prefab. Drag prefabs and build your level as you need it.

1C. Ground Paint

Paint full PBR textures with brush on any mesh using Polybrush Tool made by ProCore Team.

We've made custom ground blending shader when used with Polybrush gives you huge advantage over outdated Unity Terrain. Just Vertex Color matched with Material Texture and Paint Rock's, Wetness, Intensity to achieve amazing results.

1. Sculpt Geometry.

   1. Great for custom terrain sections and organic objects.

2. Paint Vertex Colors.

   1. Create colorful shapes, enhance textures, or even hand-paint lighting.

3. Blend Textures.

4. Scatter Detail Meshes.

Full Polybrush Documentation here: http://procore3d.github.io/polybrush/

1. Fill material texture slots with desired texture sets.

Download PolyBrush beffio Palette Asset from there:

https://www.dropbox.com/s/xgobltbmdgyucuo/Beffio.asset?dl=0

1. Fill painted mesh with black color and no alpha in order to reset vertex color data. Easiest way to do it is to use Polybrush fill tool and color preset inside a palette file which is shipped with Medieval Kingdom asset. You can also create your own color presets to use with Polybrush.

In order to paint on mesh we recommend as follows.

1. Import custom color palette which is shipped with Medieval Kingdom asset. Beffio's color palette contains 2 color presets - black color with no alpha which should be considered as an eraser and white color with alpha. In order to import palette copy file "Beffio.asset" into "ProCore\Polybrush\Color Palettes\". As an alternative you can create color presets inside Polybrush tool and save them as your own, custom palette.

2. Inside Polybrush window go to "Paint vertex colors" tab, chose second color preset (White with alpha) and using buttons above color palette tool, uncheck all of undesired color channels leaving only those you want to paint with.

Use this ready-made fog prefabs, to give your scene mood of misty games.

We're using custom made sprite to simulate particle effect volume. Just drag and drop your fog prefab and play with unity particle system settings.

5A. LOD System

When a GameObject in the scene is a long way from the camera, the amount of detail that can be seen on it is greatly reduced.

However, the same number of triangles will be used to render the object, even though the detail will not be noticed. An optimisation technique called Level Of Detail (LOD) rendering allows you to reduce the number of triangles rendered for an object as its distance from the camera increases. As long as your objects aren’t all close to the camera at the same time, LOD will reduce the load on the hardware and improve rendering performance.

In Unity, you use the LOD Group component to set up LOD rendering for an object. Full details are given on the component reference page but the images below show how the LOD level used to render an object changes with its distance from camera.

More here: Level of Detail (LOD)

5B. Textures

Consider to compress & reduce size of textures in Medieval Kingdom pack.

3D graphics hardware requires Textures to be compressed in specialized formats which are optimised for fast Texture sampling. The various different platforms and devices available each have their own different proprietary formats.

5C. Occlusion Culling

Occlusion Culling is a feature that disables rendering of objects when they are not currently seen by the camera because they are obscured (occluded) by other objects.

This does not happen automatically in 3D computer graphics since most of the time objects farthest away from the camera are drawn first and closer objects are drawn over the top of them (this is called “overdraw”). Occlusion Culling is different from Frustum Culling. Frustum Culling only disables the renderers for objects that are outside the camera’s viewing area but does not disable anything hidden from view by overdraw. Note that when you use Occlusion Culling you will still benefit from Frustum Culling.

5D. Light & Shadows

Reduce number of lights decrease shadow quality or turn it off.

Shadows - If you're aiming for mobile you probably should use only one Directional Light in your scene with very low quality real-time shadows or even turn it off.

Point Lights - you should consider to remove all point lights from your scene. 

6A. Lightweight Render Pipeline Shaders & Unity 2018 Support 

The goal of the LW RP is to provide optimized real time performance on performance constrained platforms by making some tradeoffs with regard to lighting and shading.

Lightweight Render Piepeline

The target audience for LW RP is developers targeting a broad range of mobile platforms, VR and those that develop games with limited realtime lighting needs. The LW RP performs single-pass forward rendering with one real time shadow light and light culling per-object with the advantage that all lights are shaded in a single pass. Compared to the legacy pipeline forward rendering, which performs an additional pass per pixel light within range, using the LW pipeline will result in less draw calls.

Unity 2018 Support

Medieval Kingdom works in Unity 2018 in Classic 3D Template Rendering Pipeline.
