Materials not behaving well - Arnold

[jddias56]

New to Maya.

I just build some materials (aiStandardSurface) with provided textures and they are not rendering as expected.

I have placed all the UV's in the correct place and my key light is an aiAreaLight. I am rendering with Arnold.

The gun and the glass are the biggest problems. the materials are showing up in a correct manner in the Material View.

Could you show us the shader settings and the textures please.

Thank you for the reply.

After some time and with help of another person, I was able to correct my problems.

I had to change color space of Metal, Roughness and Normal maps to RAW and check the Alpha is illumination.

Thank you very much for your time
