How does "WorldEnvironment -->Background / Mode" work

maesi

Hi to all

(Win10/Godot 3.2/GLES3)

While following a tutorial i encountered a strange behaviour. After a bit try and error I found ways to bypass the problem but I don't understand why it is this way. I have the feeling i missed some fundamentals on the way.... Can someone point me in the correct direction? (keywords to search for, some documentary how godot handels this)

problem In a 3D-Scene GridMap is not always displayed when WorldEnvironment/BackgroundMode is on "Clear Color". It seems it can display the GridMap or Meshinstances but not both at the same time. Camera-Symbol and Editor-Grids also disappear.

When the WorldEnvironment/BackgroundMode is on "Canvas" both are displayed. Same when a Light is active in the scene. When using GLES2 there is no problem at all.

It is probably a missed setting or an other stupid mistake on my side. I would really like to know where I made the mistake... Thanks for the help

light off and clear color

light off and canvas

light on and clear color

Steps to reproduce and Scene-Tree -Node --WorldEnvironment --DirectionalLight(off) --Camera --MeshInstance --GridMap

change Visibility (light, GridMap, Meshinstance) and WorldEnvironment/BackgroundMode

Hmm. You might wanna post an issue on that at Godot's GitHub page. https://github.com/godotengine/godot/issues

Make sure to search the issues first, perhaps someone already has reported the issue, in which case you should just add a comment there that you are experiencing it as well.

thanks for the direction

a similiar issue (#30330) was already posted (https://github.com/godotengine/godot/issues/30330)

Summary: it is a bug only existing on integrated graphic cards and GLES3 it happens when a MeshInstance doesn't have a material assigned to it.

when the MeshInstance has a material everything works fine.
