Possible Light2D bug with polygon

sektor-13

Hello,

I think there is a bug with Light2D and polygon illumination.

In some instances (rotation angle and/or light position) polygon is not effected by light.

In picture below: Helmet is polygon (cut from larger texture). Light2D center and radius is drawn with white circle (size of light2d texture). If i move light node one pixel down it stops illuminating helmet. Same thing happens if i rotate light to some extent.

It works normaly with sprite.

Any suggestions ?

What is the Z-index of the helmet and the light? Maybe the movement causes the Z-index ordering to get messed up, which causes the light not to render. Even if the Z-index is the case, this does sound like a bug. I would suggest opening a bug report on the Godot GitHub repository if there is not one already open for this issue.

Z index is 1. There is no difference if i change it. I tried different options with same result.

Also if i move the helmet around the same thing happens, when i move it past some coordinates. Looks like border is square shaped.

Hmm, strange. It's been awhile since I've worked with 2D lights in Godot, but do you need to provide Godot with a 2D light collider or something similar? If you do, maybe that is the issue?

Hmm i found out some similar reports. I will post it to github. Looks like it is problem with polygone and bones...
