why my normal maps is shining white? I have no idea why.I took a high strength level to show you my result. Its very confusing to see the white glow if i plug in my normal map. I also tried the bump shader same problem. I using Blender 2.8. render eevee

Hi guys i added one more picture. I have a wiered looking reflection. The only object with this color is in the inside of the building how does the reflection appear on the glas?

it's hard to understand what is your problem, do you mean your texture is much brighter that what it is without any normal map? maybe share your file (with the images packed): https://blend-exchange.giantcowfilms.com/ – moonboots Jun 14 '19 at 08:36
added 1 more picture. The white glow is within the joints. Normaly they should be darker with a slightly depth – saveit Jun 14 '19 at 09:35
Looks like your normal map is flipped vertically. Also are you using DirectX normal map as OpenGL normal map? – Jaroslav Jerryno Novotny Jun 14 '19 at 09:47
How to flip the map and what is directx and opengl normal map? There is a different? :O – saveit Jun 14 '19 at 09:55
weird because if I open your b&w picture with CrazyBump then make a normal map, it works fine, it's not inverted like yours – moonboots Jun 14 '19 at 10:11
useing materialize for maps i found some shader setup to invert it. Maybe looks a little bit better – saveit Jun 14 '19 at 10:14

invert the green channel – Bithur Jun 14 '19 at 11:07
Downloaded your picture and looked inside channels. You are indeed using DirectX normal map. See the link Bithur gave, that's the solution. Or convert it inside photoshop. – Jaroslav Jerryno Novotny Jun 14 '19 at 11:28
To give it a bit more depth you should add a ambient occlusion map as well. Normal maps that looks like they are lit from beneath are directx. – Jackdaw Jun 14 '19 at 16:21
