Once selected, the global cubemap will change:Įh, not too good looking, but it will do! Reload the map, click on the env tab in the upper menu and find your cubemap texture in the cubemap dialog box. If successful, the editor will tell you the path to the cubemap relative to your map's directory. Then head over to the env manager and press 'Build Cubemaps' (this will fail if you dont have python3 and PIL module installed) To do so you will need to spawn a cubemap_gizmo from the editors spawn menu. That's because diesel does not support realtime reflections, so map makers have to create cubemaps manually This looks wrong! Why are there buildings in the reflection even though we are indoors? A cubemap is a six-sided texture used for reflective surfaces to reflect stuff.
