@svetimas Are you just putting the HDRI in the LookDev shading or in the world settings? If you’re just putting it in the LookDev, it’s only affecting the preview. If you want an HDRI to show in your render, you need to make sure it’s in World properties. by default, this is set to a background color of grey.
If you do have it in the world settings, then what Miranda said is correct.. It should automatically show in the render unless you set it to transparent.
