Some objects doesn't show up on shader complexity view mode (Mobile)

Hi everyone, seeking for some help.

I’m trying to debug shaders but some of them just doesn’t show up when I switch to iOS preview.

Some of my observations:

  1. Landscape shader is visible in shader complexity view mode on it’s version without landmass used (checked on the mobile device, landmass works perfectly, so it’s supported).
  2. Landscape material is complex, but there’s nothing special in the trees shader, which concerns me.

Any thoughts?

Well it’s just a shader compilation bug or so. After I make some changes to the shader and save it, it shows normally.

Sometimes it disappears again and have to re-save it…
