I'm using a render texture to capture a 3D scene with a camera. However, the resulting image doesn't have alpha. I'm trying to erase the background, but it's not working. What should I do? (urp / 2022.3.62)

Check the alpha value of that camera background color. Looks all white in inspector so alpha slider is probably at 1 rather than 0 if you want it transparent

I'd also check if post proccessing is overriding the alpha
