Godot Viewports: 3 examples from real games 

Super cool video and great use of viewports! The last example is my favorite, it's a simple trick but a huge improvements. I also like to use viewports to display anything inside a particles2D. It's especially useful if you want to display text inside particles!

One other great thing about viewports is that you can toggle input events on or off. E.g. when you have a fullscreen gui overlapping other things that receive inputs. Great video and examples!

Your explanations are concise, logical, sequential and have, overall, a harmonious quality which renders a heavy impression upon mind and memory. Thankyou

I didn't know that Viewports are so powerfull

Interesting. Thanks for sharing.

Great infos, thanks!

this video literally changed my life

so whats the actual Performance cost of viewports ? if been thinking about alot of uses for them but havent implemented any. how many can you get away with since they basically all render at the same time ?

hi, do anyone get this error -render scene: can't use canvas background mode in a render target configured without sampling my main scene have `WorldEnvironment` mode canvas, = for glowing effect. my viewport, i just put usage = 2d without sampling and transparentBG = true, if i take other than 2d without sampling i will get black bg. how can i fix this?

Nice!

For the 3rd use case, you use a Sprite2D to represent the foliage, by using the texture generated by a Viewport and an AnimatedSprite2D. But what about if instead of a simple/static animated entity, it were a more dynamic/complex one? Like Actors that can have multiple animations and so. There exists any cool tricks to reduce the overhead when having many actors on screen, with different animations per action? (walk, attack, idle, etc)

Really thank you, very helpful.

Really great info here, thanks.

Thanks, I could use it to render line2D and use light2D to slowly reveal it, awesome

Good video, thx

Thank you for the examples. Your games look very interesting.

Thank you for these examples Excuse me but I would like to use a lot of subviewport at the same time in a 3d scene to take advantage of 2d nodes (anomationplayer, etc) to make a 3d tilemap. Could this cause a slowdown problem if I use a lot of them?

super intéressant, merci pour l'info ! :)

Not to put you down, but the voice recording sounds very "bassy", its hard to hear even at higher volume. Otherwise the content is very good and keep it up

Very interesting and useful.

Save Eurydice shader code updated to Godot 4.1 shader_type canvas_item; uniform sampler2D SCREEN_TEXTURE : hint_screen_texture, filter_linear_mipmap; uniform sampler2D noise; uniform float threshold : hint_range(0.0, 1.0, 0.7); uniform float border : hint_range(0.0, 1.0, 0.1); uniform vec4 border_color : source_color = vec4(1,0,0,1); uniform float start_time = 0; uniform bool active = false; uniform float duration = 1.; uniform vec4 large_border_color : source_color = vec4(1.); uniform float border_thresh_1 : hint_range(0.0, 1.0, 0.58); uniform float border_thresh_2 : hint_range(0.0, 1.0, 0.5); void fragment() { COLOR = texture(TEXTURE, UV); if (active) { vec4 color = COLOR; float noise_val = texture(noise, UV + start_time).r; vec4 behind = texture(SCREEN_TEXTURE, SCREEN_UV); float time_modulation = sin(TIME - start_time) / duration; float burned = step(1. - time_modulation, noise_val); float burning_border = step(1. - border - time_modulation, noise_val); COLOR = burned * behind + (1. - burned) * (burning_border * border_color + (1. - burning_border) * color); } }

I do not understand Viewport in Godot 4.* Aspecialy because of this new SubViewportContainer, and Subviewport... no Tutorial about Viewport of Godot 3 dosnt work anymore. I got it to work to create a viewport with multiple moving sprites as child, but when i tried to use the vieport as texture the FPS of the texture (only of texture not of the rest of the game) was so bad oO to be clear, there where moving fireflys in this viewport and i wanted to use them in one texture as waterreflection but the viewport texture looked so laggy... like 5FPS movement. And there is way to much settings, for example you kann disable 3d and 2d and its possible to do both but nothing happen there.. this node is so not self explaining and the documentation dosnt help me.

this is amazing

Very cool!

Very clever :)

I add tilemap to 3d)

Tu veux pas faire des tutos fr par hasard x)

This is an awesome video, sub from me!

A mon avis t'es français
