There seems to be something wrong with normal maps in tangent space, see attached screenshots.

Can this be fixed in the Nightlies?
Cheers.

Hi

Are you using V-Ray or V-Ray GPU ?
Could you please attach a sample scene?

Hi Muhammed,

I was using the CPU, I downloaded the latest nightly and it’s not present anymore so I’m not sure where the issue came from, but it seems to be resolved in the latest nightly.

Thanks very much
