1.0.1
Add Unity 6 support.
1.0.0
First release.
There is one single tile besides every terrain texture tile sets. This tile is a scripted tile and will automatically draw different tiles from the normal tile set as variation with each paint.
You can find the configurations of the scripted tiles at Cainos/Pixel Art Top Down – Village/Tileset/Scripted Tile.
Decoration Rate is the chance to draw a random tile from the Decoration
Basic[0, 1]Seed is the random seed to use.
Below is an example of using Decoration Rate at 1.0 vs Decoration Rate at 0.0 for ST Glass
The last group of the terrain tiles are the same as the first group, but with no collision
They are used in positions like the example shown below to prevent generating collision into higher layer of terrain.
It is recommended to use Linear color space with this asset.
You can find this setting at Project Settings/Player/Other Settings.
The demo scene requires Universal Render Pipeline with 2D Renderer to work. You can install it in the Package Manager.
After the Universal Render Pipeline is properly installed, you can use the Universal Render Pipeline Asset that comes with this asset. You can find it at Cainos/Pixel Art Top Down – Village/Rendering.
If you are using your own render pipeline asset, make sure to set Transparency Sort Mode to Custom Axis with Transparency Sort Axis set to [0, 1, 1].
Import Patch - Unity 6 package at the root folder of the asset to add Unity 6 support.
Sometimes you will get a error of [Top Down Pixel Water Renderer Feature] Blur shader not set. after importing. In this case, just follow the setup steps to add the material and shader to the renderer feature.
For the water to be rendered correctly in WebGL builds, you need to disable Auto Graphics API and set Graphics API to WebGPU in Project Settings > Player > Other Settings .
For compatiblity, the default input method in this asset still uses the old input manager. And in Unity 6.1, the old input manager is no longer the default option.
If you encounter any error regarding the input system. Please change the Active Input Handling in Project Settings/Player to Both .
By setting the move value of Increment Snapping to 0.03125 (1/32), and press CTRL when moving objects, the objects can be placed perfectly aligned to the pixel grid.
This asset is uploaded as a complete project to included project settings. The Top Down Pixel Water renderer feature should be well setup by default.
If you need to set it up by yourself, follow the below instruction:
Add a Top Down Water Renderer Feature to the render pipeline asset.
Assign the water material at Cainos/Pixel Art Top Down - Village/Material/MT Top Down Pixel Water and gaussian blur shader at Cainos/Pixel Art Top Down - Village/Shader/SH Render Pass - Gaussian Blur to the Reference foldout.
Set Terrain Layer Mask
The rendering of the water is quite performance heavy. When optimizing for mobile platforms, please try the follows settings.
On Assets\Cainos\Pixel Art Top Down - Village\Rendering\Universal Render Pipeline Asset - 2D Renderer, find the Top Down Pixel Water Renderer Feature and tweak the blur settings of the water.
The idea is to make Downsample as large as possible and Kernel Size and Blur Pass as small as possible while maintaining an acceptable water rendering quality.
On the Universal Render Pipeline Asset, set Render Scale to 0.5. Mobile platforms usually have much higher DPI so we do not need to render at full resolution.
On Project Settings/Player, Set Graphics APIs to Vulkan, enable Multithreaded Rendering and Graphics Jobs.
With these settings, the demo scene can run at 60fps at Xiaomi MIX 2S, a pretty old device.
Water Layer MaskTerrain Layer MaskWater Layer MaskFind the PF Top Down Pixel Water in Cainos/Pixel Art Top Down – Village/Prefab/FX and drag it to the scene.
The water effect is achieved through a custom shader combined with a Renderer Feature. Below is a breakdown of the rendering process.
The water shader ASE Top Down Pixel Water is made using Amplify Shader Editor. If you own this asset, you can open the shader as a graph to see how it is made.
Render terrain and water-touching objects defined in Terrain Layer Mask into a texture named Terrain Tex.
Apply a gaussian blur to the alpha channel of Terrain Tex using parameters from Water Color Blur Setting, creating Terrain Blurred Tex.
Then we can use the grayscale of Terrain Blurred Tex to lerp between Shallow Color and Deep Color to create a gradient from shallow water near the shore to deep water far from the shore.
Shift the alpha of Terrain Texture down by one pixel size (1/32 in world space as this asset is 32x32 per unit), color it with Foam Color and blend it with the base water color.
First we need to create a mask texture Under Water Mask Tex in the same way as we create the Terrain Blurred Tex in the Water Color step, but with parameters from Under Water Mask Blur Setting.
For the content to be refracted, we use the Terrain Tex and move it down twice, each by 0.4 tile size, mix them together and color it with Under Water Color.
For the distortion effect, apply time-animated Voronoi noise to UV coordinates when sampling from Terrain Tex.
Then we can mask the result with Under Water Mask Tex to create a fading effect and blend it to the base water color.
We use a foam texure TX FX Water Foam from this asset, sample it with the UV multiplied by 2.0 in the vertical direction to match the perspective of the top down scene, and disturb it with a time-animated noise.
For the mask, we use the maske value from Under Water Mask Tex, but move it down by 0.5 tile size and power the value by 2.5 (make the white part wider).
The highlight pattern is made by multiplying two noise with different size and moving direction, then powered with 6.5 to extract the most light color, and stepped by 0.3 to make it flat.
The UV of the noise is multiplied by 20 in the vertical direction to make it much wider horizontally.
Then we can use this as a mask to add Highlight Color to the water to create the final water effect.
