Lighting on Mobile issues (4.10)

Hi Tim, firstly I wanted to thank you for uploading this super helpful project! This really assists me to understand what kind of shadowing works on mobile.

However, I was wondering if you could clarify a few things, using the “mobilelight” project you uploaded above:

  1. With Mobile HDR disabled in the project settings, and the lighting built on production quality, the directional light which was set to “Movable” shows shadows from both the moving and static object, however it does NOT show the red modulated shadow color, either in the editor’s viewport when set to Android preview, or in the Mobile Preview (PIE).

  2. When the same directional light is set to “Static” (and lighting is built), only the static cylinder casts shadows and the moving one does not, in both the viewport and Mobile PIE.

  3. Additionally, when the same directional light is set to “Stationary” (and lighting is built), the red shadow finally shows in the editor’s viewport, but ONLY from the movable cylinder, not the static one. However, in the Mobile PIE, no red shadow is shown on the moving cylinder, but a black shadow shows on the static one.

  4. The “Shader Complexity” viewmode (shortcut ALT-8) in the Editor shows bright red for everything, while the “Shader Complexity” viewmode (shortcut F5) shows a dark maroon, as if the scene is actually quite good.

  5. Lastly, the default preview mode of the Mobile Preview (PIE), which should be “Lit” (shortcut F3), looks extremely blown-out compared to the Editor’s viewport “Lit” mode (when set to Android preview). In fact, the PIE’s “Lit” mode, looks nearly identical to the Editor’s “Light Complexity” viewmode (shortcut ALT+7). (I actually thought “Light Complexity” was supposed to show a green to red rendering of everything.)

Is all this behavior normal?

Thanks so much for your assistance!

Sincerely,
Adam Janz
