Lighting Layer + Tilemap Object giving visual issues

GDevelop general Bugs reports

Describe the bug

Seems having more than one tilemap on one or multiple layers while you’re using a lighting layer, causes all the tilemap visuals after the 1st one to have a weird white washed look to them. While the main/1st tilemap looks normal.

I’ve tried putting them to the same z-order as the 1st tilemap, even duplicated the 1st tilemap and it does it on the duplicated.

But when I set all light objects on the map as debug, everything looks perfect besides seeing a red box on the lights, lol.

Steps to reproduce

  • Put multiple tilemaps, overlapping helps notice it
  • Make a lighting layer with at least one light source

I’ve had this problem for a long time, apparently it’s something that is difficult to fix but does have an effective work around solution. Here’s what one of devs said on Github:

Also, if you add a 3D object (cube for instance) in the scene’s objects, the bug does not appear. Tilemap rendering when using a light · Issue #7091 · 4ian/GDevelop · GitHub

I tested this and it works. Just and a 3d box object, no need to add it to the scene.
