What I'm missing?!?

Unity Engine

Hi guys,

I need a help about this: I make normal maps and other texture maps with a tool (i.e. MindTex) and then I import the textures files (Normal, Ambient occlusion, Height, Specular, Diffuse, Self Illumination) on Unity 3.x and I create materials using my custom shader too.

Below I attached a screenshot about a material how I see on MindTex and the same material how I see on Unity.
I don’t understood why there is this big difference.
Someone has some suggestions to tell me?

Thanks in advance

Invert the green channel of your normal map.

In Map exporting settings on MindTex I have this possible parameters to choose about Normal:

-Format: Gray or RGB or RGBA

  • Channel generation: N.r; N.g; N.b

Which is?

I don’t know what MindTex is.

Open the normal map in an image editing tool and select the green channel and invert it.

In GIMP I selected the green channel and inverted it but when I try to reimport Unity tell me to fix the normal map pressing the button on inspector and the result is the same, not change.

UPDATE: Great! I was wrong to select channel, so inverting red and green channel I obtain the best result like in first pic.
Thank you very much for your support!

We used the channel generation: N.r;1-N.g;N.b
to fix the inverted green issue with MindTex.
