Description

Effects using translucent materials using Mobile Separate Tranclucency and DepthFade do not display properly if DoF is enabled.

By applying CL # 4558661 shared by [Link Removed], Android works normally. However, iOS does not solve this issue. Incidentally, if I don't use DepthFade, Separate Tranclucney worked fine even in iOS by applying CL # 4558661.

As I confirmed with Xcode's OpenGL Frame Capture, when using DepthFade and SeparateTranslucency, it seemed that drawing processing was not running. Also, if I don't use DepthFade, the rendering process was running even before CL # 4558661 was applied.

Steps to Reproduce
  1. Enable Separate Translucency
  2. Put particles using material enabled separate translucency and used depthfade node.
  3. Enable High Quality Gaussian DoF on Mobile
  4. Run on iOS

or

  1. Open attached project
  2. Run on iOS

Expect : display the effect correctly
Result : the effects are not displayed
