How to add emission to a texture shader?

Hi Folks.

Okay, this has me stumped. I have a box that I need to be lit up. I doesn’t have to illuminate the world around it, I just need this box that is always bright. Hence, if turn on emissions in the box’s Standard Shader, it works great!! But I need a texture on the box and in order to do that I have to go into Legacy Diffuse Shader which lets me add the texture, but I lose the emission of the box and it’s not bright any more. How do I put a brightly lit texture on a box?

EDIT:
Never mind, I figured it out. I use an Unlit Texture and it works great.

Why can’t you just add the texture to the standard shader? There’s no reason that I can think of that you’d ever need to use the legacy diffuse shader.

I need the texture to receive no shadows, receive no light from the scene, cast no shadows, and to be illuminated so regardless of how dark or bright a scene is, it’s always the same. I couldn’t figure out how to do that with Standard Shader, or legacy ones either. But the Unlit Texture worked.
