Hello. I use Godot 3.5. I have a texture, partially transparent, set in the "texture" field of Line2D. Whatever the option, tile our stretch the result is the same. I see the line color behind the texture. That breaks the effect I'm looking for.
You could try changing the line color to white or fully transparent.
When its transparent the texture will be transparent too. The white color maybe the better choice to preserve the texture. Thankyou
