Supported Rendering Features

Below you can find listed information on what rendering features we currently support, plan to support and ones that we do not.

Supported

These features are all available right now to use with the Unity Playworks Plugin Engine:

• Standard & Custom Shaders from Unity (which means the converted results are 1:1)

  info

  Make sure the shaders you use support Shader Target 3.0. If not they can most likely be converted/adapted.

• Forward renderer path from Unity's built-in render pipeline.

  info

  We do not support other rendering paths from Unity's built-in pipeline, only ForwardPath.

• Normal Maps

• Spherical harmonics: LightProbes, ReflectionProbes, Ambient Probes

• All built-in Unity uniforms (for lights, harmonics, matrices, screenparams etc.)

• Unity Fog (Exponential, Exponential Squared & Linear Fog)

  caution

  Calls made to fog via scripts will cause shader issues in Luna, be sure to use the lighting settings window in Unity instead.

• Baked lightmaps

• MaterialPropertyBlock

• Dynamic batching

• Realtime Shadows

• Linear color space

  caution

  In order to work property, make sure to enable Webgl2 checkbox ( Settings > Addvanced ).

  

  There are some limitations on Linear color space support. Following features are not implemented:

  • Texutre3d
  • Texture2DArray
  • Cubemaps
  • Runtime texture creation

What we plan to implement

These are features that we have on our roadmap to add to the Unity Playworks Plugin Engine, be sure to check out our release notes when we update Playable to see what new features are available.

• Static batching

Not Supported

Unity Playworks Plugin initializes WebGL 1.0 context by default. It can be changed to WebGL 2 in Settings/Advanced tab (starting from Playworks Plugin 6.0.0).

To make sure Unity Playworks Plugin is able to utilize all your shader code, please try running the game targeting OpenGL ES 2 or OpenGL 3 API.

Below are features we currently do not support:

• Shader target 3.5 and above (Supported with Playworks Plugin 6.0.0)

• HDR (because of lack of float textures)

• Color values from fragment shaders are clamped01 for WebGL1.

• Deferred rendering path

• Native compression

• Optimized graphics API (instancing, cbuffers, vertexBuffer partial update)
