Multiple viewport scaling issues

[desert falcon]

I have tileset with 8*8 tiles. I want my in-game view (not menus). I want the game to render at 380*180 (16:9) and upscale to match viewport size (which will likely be higher than 320*180). But I don't want menus to have this resolution. Given this resolution, it should be possible to see 40*22.5 tiles on screen. My problems are

• How do I make render resolution different for HUDs and Game?
• How do I have to adjust camera to render that way so 40*22.5 tiles fit a screen?

And also, if my viewport size is the same as the game size (320*180). How can I make the viewport biggen on start to debugg better? I don't want full screen because I use always on top with a size of around 928*512 to have a game view big enough to view but not big enough to cover all the editor

Edited: I tried using 2 viewports, the root one (that it's by default there, I didn't add anything) and a subviewport container with a subviewport node inside the HUD). I did this trying to get the demo project for viewport to work but it doesn't :(

I just want to render my game at a low resolution and the HUD at native

You need to separate your game view with your UI view by using multiple viewports. Check this demo for an example implementation of this: https://github.com/godotengine/godot-demo-projects/tree/master/viewport/3d_scaling

Ohhh that's exactly what I was looking for! The description example is exactly my case. I'll carefully check that. Thank you a lot! ^^

In project settings, override window size.

But that won't make the hud render at full resolution

If you want fullscreen, check fullscreen

I tried this from master branch, but it gives me a warning because SubViewportContainer is set to stretch and thus SubViewport size can't be changed. If I disable the stretch property it doesn't work as expected as of course, it doesn't stretch. Do you have any idea on how to solve this? (I will remove solved tag for now)

I want to render the game at one resolution scaling it to viewport size and on the other hand I want the hud to render at native resolution. I have to use viewports as rsubtil suggested, I just need to figure out how to make them work. Your solution would work if I wanted also the HUD to have that resolution but sadly it's not the case 😔

[sweet karma]

Do you mean you want you HUD to be a different size of the viewport?

[desert falcon]

Kinda, I want the game to render at 320*180 and scale to fit the viewport, while the HUD render at viewports size. Like what it says here

[sweet karma]

Hmmm, there's an aspect ratio control node, that might be useful to keep the HUD the same size all the time while scaling the game view differently.

Are you using canvas layer for your HUD?

[desert falcon]

Yep, canvas layer with control nodes

Multiple viewport scaling issues

Alright it seems I can configure the viewport nodes and it works, but I can change the size at runtime, hmmm

[agile sequoia]

You can set the size 2D override for the viewport, and it will enforce that resolution no matter the actual size of the viewport

I'll send an example, just a second

• Set the SubViewport Size 2D Override to your desired resolution, and enable Size 2D Override Stretch

• And in your SubViewportContainer, enable Stretch

Then the subviewport will maintain that resolution independent of the subviewport container size

If you also want it to preserve the aspect ratio, check what raistlintheweezymage said and place the SubViewportContainer in an AspectRatioContainer, and specify your desired aspect ratio
