If you just take a wall (as in the video) and replace its texture by your tree texture, then it should still be rendered correctly without any self-shadowing (you don't have to change any masks). The wall shader essentially reads the brightness value from the background layer at the position just below the bottom of the wall texture. Maybe your light occluders are too large, or they are positioned too low, thus casting a shadow on the tree. Also make sure that the tree texture does not have any scaling or offset, since this may cause problems with the shader. Concerning your last question: Did you set up your scene like in the video? Which version of Godot are you using?

@@SpeckhoferEnterprises Thank you for your response! I managed to get it work partially and discovered what is the problem: it seems like what breaks the shader system is the lower viewport resolution, which I set for my game (320x180). The object then is getting self-shadowed from the shadows created by wall shader, not those casted by occluder. When the light source is behind the object, it is partly lit from the top. When I set the viewport resolution in project settings to 1280x720 it starts working. The same also applies for the editor view: it works only, when it is zoomed out to a certain point (the change is not sudden, but rather the shadow slowly fades in and out starting at the top). Another problem I encountered is that the method you used for the shader doesn't work that well with more 'organic' shapes. Basically, when the object's sprite doesn't have straight base, the shadows are still created based on the straight line at the bottom of sprite, thus resulting in its weird behaviour in those cases. The trees on the other hand don't get fully shadowed when under the light source, because of the shape of my occluder which covers just the base of the trunk.

First, you can change the order of the nodes in your scene and move all background elements up in the scene tree (so they are rendered first). You can also edit the Light Masks of your nodes, the Occluder Light Masks of your light occluders, and the Item Cull Masks of your light sources to decide which lights and occluders affect which nodes. I hope that helps!

I tried to reproduce this issue, but I didn't get any glitches. You can try resetting all modified settings of your character sprite, e.g. its scale or Z index (and make your character a child of the same Y-Sort node as the walls). Or you can also send me the project (or a minimal example) as a zip file, then I will try to fix it (you can find my email address in my channel details).

@@SpeckhoferEnterprises deleted my old response because that was't the problem! apparently, if you use spritesheet for animation, the shader will get the UV value from the entire spritesheet and use that region UV. so it wasnt sampling the screen correctly

@@pdd5793 That makes sense! In that case, it should be easy to compute the current region's uv coordinates: For example, if the spritesheet has 8 colums and 4 rows, then replace UV.x by fract(8.0*UV.x) and UV.y by fract(4.0*UV.y) Alternatively, you can split your spritesheet into single image files and use them as SpriteFrames in an AnimatedSprite2D.

*The following should work for tilemaps:* Suppose you already have a background layer with the MultiplyShader like in the video (this may also be a tilemap, e.g. with floor or grass tiles) and you have a texture with wall tiles. - Add a TileMap to your scene and create a new TileSet. - Adjust the tile size and add an Occlusion Layer under "Rendering" - "Occlusion Layers" in the TileSet properties. - Add the texture containing your tiles to the TileSet resource and draw occlusion polygons onto the wall tiles which you want to cast shadows. - Assign a new ShaderMaterial to your tilemap, using the following shader. This is important: You have to adjust the value of "Tile Height" in the shader parameters to the actual height of your tiles in pixels! (If you need tiles with varying heights, you will need separate tilemaps, one for each height.) // TilemapShader.gdshader shader_type canvas_item; render_mode unshaded; uniform sampler2D SCREEN_TEXTURE : hint_screen_texture, filter_linear_mipmap; // Note that this shader only works for tiles of the following height: uniform int tile_height = 16; void fragment() { int rows = textureSize(TEXTURE, 0).y / tile_height; // number of rows in the texture float uv_height = (SCREEN_PIXEL_SIZE.y / TEXTURE_PIXEL_SIZE.y) / float(rows); // ratio of tile height and screen height // Get vertical UV coordinate with respect to current tile instead of whole texture: float uv_y_inside_tile = float(rows) * UV.y - floor((float(rows) * UV.y)); // Compute the uv coordinates (with respect to the screen) of the bottom of the current tile: float bottom_y = SCREEN_UV.y + (1.02 - uv_y_inside_tile) * uv_height; // Read lighting value from this position: vec4 lighting = textureLod(SCREEN_TEXTURE, vec2(SCREEN_UV.x, bottom_y), 2.0); // Combine texture and lighting: COLOR = texture(TEXTURE, UV) * 2.0 * lighting; }

Hi, sorry for the late response--a lot's happened in the last week and I'll have to shift my focus elsewhere. First off, thank you so much for providing all of this! It works well, but I ran into a few issues that you can see in this video (different account): kzfaq.info/get/bejne/r8xzlbVhyrmuqZ8.html I tried setting the tile heights to 32, 64, 128, 144, and 160, and you can see the various effects on it. It's unlikely that I can continue with this any time soon, but I wanted to give you an update. Thank you so much, again!

​@@uNkNowN5642 you are welcome! The issue with your character's head being in the shadow should be easily solved by giving your character sprite a material which uses the WallShader (also make sure that "Use Parent Material" is not checked in the "Material" tab). This way, the lighting intensity on your character is taken from right below its feet, whereas without this shader, the character is treated as a flat object lying on the floor, and therefore, the occluder of the wall casts a shadow onto the character's head. The wrong lighting on the walls might be caused by some scaling issue. The "Tile Height" shader parameter should always be the actual height in pixels of your tiles, as it is used to compute the number of rows in your tileset texture (by dividing the texture height by a single tile height). The result is needed to convert the UV coordinates from a small rectangle of your tileset texture to the whole unit square, i.e., values from 0 to 1. I suggest that you try setting "Tile Height" to 16 and, just for testing, make the wall just one layer of 16x16 tiles and see if it works. Also, the height of your tileset texture should be a multiple of 16 px. If this simplified version works correctly, I would create a 32x32 or 32x16 tileset for your walls such that you don't need two rows of tiles stacked on top of each other to construct a wall, but just one row. Then you can set the "Tile Height" in the shader to 32 px again. If you wish, you can also send me your project files, and I can try to fix the issues!

Vielen Dank!

Danke!

I have finally made a tutorial! kzfaq.info/get/bejne/a6hhfJRhusXUpmw.html

Thank you!

If I remember correctly, the arms belonged to two different minifigures which were placed directly to the left and right of the camera lens.

Thank you! I used 24 fps.

Yeah 😂

Vielen Dank!

Thank you very much! I watch your videos regularly and I think they are really great!
