Normal map in selected polygons only?
I’ve applied materials to polygon selections lots of times, but now I’m trying to make the same with a normal map involved, and it isn’t working.
I’m modelling an old Canon camera, which has all the logos and controls and everything engraved or machined directly over the metal. I’ve engraved the main details like the frontal Canon logo to keep its details, but I expected to define other minor details using polygon selections.
As you can see in the screencap, I’ve assigned the main metallic material (still work in progress) to the upper part. The black paint inside the logo is a different material assigned to a polygon selection. And so on.
For the figures at the right side of the image I’m using a material made of the same base metal material, blended with the black paint for the letters and numbers (using a mask) and a common normal map. But adding the normal map makes it look weird.
Is it possible to assign a normal map to a polygon selection? Is there a simple way to do this?
I’d appreciate any help. Thanks!

Hi Jordi,
After uploading your texture to the map channel, you have to click on the arrow next to the Texture, then go to Effect>Normalizer so the appearance will be fixed. You could control the engraving using the options under Method, and after clicking on the blue texture, you can control the intensity using the Strength value, as in the attached screenshots. I hope this is useful for you.

Hi, Thanks for your interest.
Well, I’m using Redshift materials, and there isn’t a normalizer tool… but your suggestion has led me to find a tutorial about C4D’s own normalizer (interesting tool!), and there they talk about the gamma for the normal map, and this has reminded me about color spaces in maps… and voila!
It seems that setting the texture node color space to “auto” doesn’t work, and it needs to be manually set to raw / linear. Now it looks much better.
Thanks anyway for your time!
