Title: Light reflections on silver
Post by: DEVS on August 01, 2017, 01:23:47 AM
What is the right set-up to make the text visible? I have tried in many ways but the reflection of light creates a shadow over the engraved letters :'(

Rotate the environment to catch the shadows? Turn the brightness down a bit? Try a different lighting environment?

My number-one advice would be to add small radii on the edges of the letter geometry.
The issue is that, no matter what lighting you are using, there is no geometry to catch the highlights.

Adding small edge blends will make a huge difference.

I did and tried everything, even changing the environment and adding light points but I could not get a better result than what you see :-\

With which command can I illuminate the edges? It would be a good idea :-)

For best results, you'd have to add the rounds in your CAD application.

If you are using KeyShot Pro, then you can also try the Rounded Edges feature in KeyShot.

I have the same issues with rendering embossed/debossed plastics and glass for automotive lighting, and the best solution I've seen and started using is rendering a second time with the Occlusion material applied to the model, changing its type from Diffuse to Flat, and layering the occlusion rendering over the original in Photoshop as a Multiply layer. YMMV.

Can you give me an example through screashoot?
