Can a RenderTexture be larger than game size?

[jorbascrumps]

Hi all,

I admit I may be misunderstanding how this is supposed to work, but I can't seem to make a RenderTexture that's larger than the game size. For example, if I define my game as being 800x600 and then create a RenderTexture that's 900x700, then anything drawn outside 800x600 won't render. Can anyone shed some light on this, please?

Thanks

You would have to move the scene camera to see the rest. Or just scale down the RenderTexture to see the whole thing.

My current setup has the camera follow a player-controlled Sprite using `startFollow`. The RenderTexture is the size of the level with only a portion of the level viewable at any time. When the camera moves with the player, the edges of the RenderTexture become visible.

To see what I mean, you can add the following to this Labs example:

this.add.renderTexture(0, 0, 720 * 2, 600)
    .draw(player, 790, 100);

The crate should be cutoff. Note how the RenderTexture is the size of the camera bounds, which is more than the game size.

When you draw to a RenderTexture, it's not affected by the scene camera or the game canvas, AFAIK. It's just a blank texture of a defined size.

Right, but it doesn't seem like it's respecting the size that I've set (ie, one larger than the camera's viewport but still within its bounds).

Looks like this is to be fixed in v3.16!

This is happening to me in version 3.54.0, the snapshot function crops the render texture to gamesize, apparently the scissors doesn't update to the new render texture size, or maybe the scissor size is limited to game size?
