Welcome :tada:…

But this… just depends on the placement of your light source…

Same idea but using bevel with custom fall-off to undercut the text so there is always a shadow as well as some AO to play with…

Hello, I tried an approach with the traced textures technique.

Traced texture shadows

The inner shadow effect is achieved using two tracers, one for the blurred shadow effect, and other tracer for the mask (the traced mini scene is placed 10x10 units apart). The two tracers have the origin vectors at slightly shifted positions (with Vector Math>Add).

Detail of the nodetree

In the example you can also see a drop shadow generated with the same principle.

The main issues are:
You have to be somehow familiar with the technique. You can take your time to know it in its dedicated thread.

Anyway here is the file to play with it.
Logo Traced Shadow_v2.blend (277.1 KB)

Open Shading Language is already turned on in the render settings of the file.

The other issue is that the inner shadow trick is the “LOGO” background color over the “inner shadow color” and by the nature of the blur method the full background is noisy (as can be seen in the detail of the top right viewport).

Hope it helps.
