So I've been using Light2D for godot for my TileMap 2D game. Only problem is it exposes the tiles borders. See. Image Below.
For anyone coming here because they are seeing this issue on an isometric TileMap, select the TileMap in the Scene panel, expand the Cell category in the Inspector, and make sure that Y Sort is ticked. This will resolve the overlapping lighting issue.
The issue is when you set your tiles overlap.

I have two simple translucent circle sprites that I'm using as fake shadows (shown below) under some characters (not shown below). When the characters get close enough, sometimes their shadow circles can overlap - which is fine - but thanks to the default blending it doesn't look right. I want the shadow circles that do overlap to be visually merged/mixed so they maintain the same opacity, but instead they add together where they overlap like this: I have to imagine there's some way to make this work with a shader, but I'm so bad at shaders that I can't seem to figure it out. Does anyone know how to solve this?
So I have an instanced scene that is supposed to be the child of a colour rect in my tree. I want to randomly generate the nodes, but I also want parts of the view to be cut off if the texture no longer is above the main section. I know you can render nodes below their parents, but I don't know if stopping part of them from rendering is physically possible.
In this image I want the bottom circle to remain the same, but the top circle to not show anything above the dark purple box
This is the node tree in the editor
Is there any way to do this directly, or am I gonna have to use a viewport of some variety?
I believe what you want is to set rect_clip_content to true on the ColorRect (or whatever Control). Making invisible any part of its children outside of it.
From Godot's documentation:
bool rect_clip_content
Enables whether rendering of CanvasItem based children should be clipped to this control's rectangle. If true, parts of a child which would be visibly outside of this control's rectangle will not be rendered.
If what you want is the opposite, perhaps you can use z_index to have something render on top, occluding the parts you don't want visible.
There is also a trick you can use with lights (including 2D lights):
Make a light that matches the area you want things to be visible.
Set a custom material that will be transparent by default, but visible on the light pass. The simpler way to do this is to set the light_mode of the material to "Light Only". You could also do it with a custom shader instead.
Making something disappear with light, in 2D, is impossible. In 3D, you can use flags_use_shadow_to_opacity. That is how you make a shadow catcher.
But, there is one more trick: you can use a mask. This should give you full control of when to show or hide things. So, if none of the above solutions works for you, use a mask. I have an explanation in a different answer. See also: How to crop sprite in a non-rectangular form?.

I am using three.js and created a basic scene with a few meshses rendered with some basic lighting . My torus geometry was previously pointy with few polygons but I was able to smooth it out by adding more segments but now I would like to straighten the lines out in my cube. They seem jaggy. In the pic I am including my render on the left seems a lot jaggier then the example I am following on the right. I have even set width and height segments to very large values (200). Any Ideas why the aliasing/jagginess?My render on left, example on right
I'm trying to create a layout in this sketch
I want to have a vertical slider in the center, one SpanLabel on the left and another on the right.
I've tried using BorderLayout, but the SpanLabels overlap the slider if their texts are long. Is there a Layout that I could use to achieve a similar style or something I could do to fix BorderLayout?
CenterAbsolute and CenterCenter don't help in fixing this.
I'd use a TableLayout with percentages for each column to achieve this sort of layout.
BorderLayout assumes the preferred size of the elements on the sides/top/bottom isn't too big to cover everything so it's a bit problematic in some use cases.
I know this has been asked many times, but not quite the way I'm trying to solve it.
I have Labels in a Panel on a UserControl, and the UserControl goes onto a form.
The Label.BackColor = Transparent.
The panel is from DevExpress, and I've set a gradient background.
Problem: The Labels aren't transparent; they each show as a white solid rectangle around the text. (I presume the white comes from the Panel, as the first of the two gradient colors is White.)
Everything I google about this problem says I need to roll my own Label control and fire off peculiar GDI+ commands, and Invalidate the control, and hook the Paint event and sing a stirring sea shanty and hold one foot above my head and...
Really? Doesn't the Label allow ".BackColor=Transparent" ? Why doesn't that work?
And what's the best way through this?
Somehow it turns out I never tried making the Label backgrounds transparent.
I am not a proud.
