• Unity 2019.3.0f3 or later

• Shadow Caster
  • Create ShadowCaster pass.
  • Please check if you want a shadow of a raymarching object.
• World Space
  • The given pos in a distance function becomes world-space one.
  • If not, pos becomes an object-space one.
• Object Scale
  • If checked, pos in a distance function is scaled by the object scale.
• Check If Inside Object
  • Check if the camera position is inside the object, and then if so, emit ray from the near clip plane.
  • Please set the Culling in Material Properties as Cull Off.
• Ray Stops At Depth Texture
  • The occlusion with the other objects is calculated using the CameraDepthTexture.
  • Please check this with the setting of a transparent object.
    • Set Render Type as Transparent.
    • Set Render Queue as Transparent or greater.
    • Uncheck ZWrite in Material Properties.
  • And please check URP is generating CameraDepthTexture or not in Depth Prepass stage from Frame Debug window.
    • If you don't use Cascaded Shadow, the texture may not be created.
• Ray Starts From Depth Texture
  • The ray starts from depth texture to avoid the same calculation done in both DepthOnly and ForwardLit passes.
  • Please check URP is generating CameraDepthTexture or not.

• Render Type
  • RenderType tag value like Opaque, Transparent, and TransparentCutout.
• Render Queue
  • Queue tag value like Geometry, AlphaTest, and Transparent.
• LOD
  • LOD setting in a shader.
• Object Shape
  • Clip the raymarching area inside cube or not (see below).
  • CUBE
    • 
  • NONE
    • 

PostEffectOutput is the following type in each template.

• UniversalRP > Lit
  • Same lighting as the built-in Universal Render Pipelin/Lit shader.
• UniversalRP > Unlit
  • No lighting, and same as the built-in Universal Render Pipelin/Unlit shader.
