How can I render a surface texture inset from the edges of the window?

[tqwewe]

I'm looking to have bevy and tauri working together as an attempt at making a bevy editor, and I'd like a middle "viewport" to be rendered in bevy, while the surrounding area is html UI.

How can I render a surface texture (eg, bevy frames) not at (0, 0), but instead indended to make room for surounding UI?

In the example, the red is the rendered frame, and the white is transparent and not rendered to.

You can set the viewport with https://docs.rs/wgpu/latest/wgpu/struct.RenderPass.html#method.set_viewport which will act like that part of the texture is what you're rendering to.

Thanks for the answer! I tried that but was getting an error saying the arguments I passed were incorrect. is there any examples on how to use it? I couldn't get the arguments correct.

I don't have one off hand, but what parameters were you trying to use that didn't work?

I tried .set_viewport(100.0, 100.0, 500.0, 500.0, 0.0, 10.0). I don't really understand what I'm doing with WGPU and kinda hacking it together, and wasn't sure what the min and max depth meant, so I just put random values of 0.0 and 10.0.

Ahhh the depth is almost certainly the problem, the maximum depth range is from 0.0 -> 1.0, so putting those values should work for you.
