What a good way of adding a fake inner shadow to this object?

This object has a blue emission material. I’d like to create a fake inner shadow at the top right.
Is there a good way of doing that?
I tried a boolean cut into the base and tried to sink it down a little but that didn’t go well.

I was thinking of adding a gradient texture, but thats not working either (nodes disconnected below).

Have you tried to fake it connecting the color ramp to Emission Node > Strength?

I got it to go to the right. But I want it to be right and top.

A simple and fast way: simply add another texture with different orientation and mix it with the previous one.

Playing with mix node:

You know how it should look, the right texture and his math is up to you.

Just rotating it could be done like this

What am I doing wrong here? My Multiply doesn’t look like yours. The rectangle is coming out just white.
Another difference is how you join the Texture coords to the two mapping nodes. I’ve done it this way below, I think thats the same, right?

Your Multiply is a MATH node. You have to use a COLOR node (Shift+A>Color>Mix Color).

I think you are using a old Blender version, isn’t it?
In the latest the mix node is ‘unified’.

Yes.

I’m still getting the white rectangle. My nodes seem to be the same as yours apart from how the far left Text coord node connects. I dont know how to connect it like yours. But I wouldn’t think that should be the issue should it?

It’s the same thing, it’s just aesthetics.

Please try these 2 steps:

  1. object screenshot of what you got just connecting directly the first color ramp to Material output node

  1. same as above but with the 2nd color ramp

2nd: is black

Ok, first thing first, it’s trivial but essential: is scale transform applied and 1?

After this try to set a rotation of -90° in 2nd mapping node
