Hello guys, I have a weir issue with my normal map

Here's my low and high poly

Here's the result :thumbdown:


Anybody has an idea why I am having this issue?

Thanks for your help guys,

The gist of it: You details are not beveled. Normal maps needs beveled details so they're able to read the XYZ information.

For more info, check out the Polycount Wiki on Normal Maps.

Yup, probably the simples fix would be to select all those small rectangular areas and just locally scale them down along height and width axis.

normal maps do not contain height data, they contain "change of angle" data. This is why you need to have beveled edges to show.



You would probably benefit from poking through the wiki here:

Worked really fine, I had to re do the high poly version created by my colleague... Nice guys, I was really away form the solution.
