Unity 2018 Upgrade Tools

This library helps you to upgrade your existing project to Unity 2018.

Analyze Shader Usage

using Unity2018UpgradeTools;
using UnityEditor;

public class Unity2018Upgrading
{
    [MenuItem("Assets/Analyze Shader Usage")]
    static void Analyze()
    {
        Materials
            .SearchMaterials(new[] { "Assets/Materials" })
            .AnalyzeShaderUsage()
            .Log();
    }
}

This will generate logs in console that indicates which shaders are used by materials.

It's useful to find shaders/materials you should rewrite for SRP compatible.

Bulk Update Shaders

using Unity2018UpgradeTools;
using UnityEditor;

public class Unity2018Upgrading
{
    [MenuItem("Assets/Bulk Update Shaders")]
    static void BulkUpdate()
    {
        Materials
            .SearchMaterials(new[] { "Assets/Materials" })
            .UsingShader("Unlit/Color")
            .ReplaceShader("Lightweight/Unlit/Color");
    }
}

This will update a shader of materials that has a specified shader to new shader.

Bulk Update Particle Systems

using Unity2018UpgradeTools;
using UnityEditor;

public class Unity2018Upgrading
{
    [MenuItem("Assets/Bulk Update Particles in Assets")]
    static void UpdateParticlesInAssets()
    {
        GameObjects
            .Search(new[] { "Assets/Materials" })
            .ParticleSystems()
            .EnableGPUInstancing();
    }

    [MenuItem("Assets/Bulk Update Particles in Scene")]
    static void UpdateParticlesInScene()
    {
        GameObjects
            .AllInScene()
            .ParticleSystems()
            .EnableGPUInstancing();
    }
}

This will update particle systems that has billboard render mode to use mesh & GPU Instancing.

Find & Update Missing GPU Instancing Materials

using Unity2018UpgradeTools;
using UnityEditor;

public class Unity2018Upgrading
{
    [MenuItem("Assets/Bulk Update Missing GPU Instancing/Dry Run")]
    static void ShowMissingGPUInstancing()
    {
        Materials
            .SearchMaterials(new[] { "Assets/Materials" })
            .FindMissingGPUInstancingMaterials()
            .Log();
    }

    [MenuItem("Assets/Bulk Update Missing GPU Instancing/Run")]
    static void UpdateMissingGPUInstancing()
    {
        Materials
            .SearchMaterials(new[] { "Assets/Materials" })
            .FindMissingGPUInstancingMaterials()
            .EnableGPUInstancing();
    }
}

This will find materials with a shader that has a GPU Instancing variant but with a Enable GPU Instancing field is off.

• Dry Run will display such materials in console.
• Run will set material's Enable GPU Instancing to on.
