Hi
(attached png and blend file)
Could you please tell me why the world light is coming from the left (x axis). I think everything in the scene is centered.
Thank you

I think the normalmap is causing this.
Can you attach it (or pack into the file)?
When I render it looks like this:

Packed file attached.

Re: World light always from the left?
yup, caused by normal map...
from my experience, using normal map with Height above ~ 0.3 (gamma 2.2) i always get some sort of shading issues / gamma 1 looks fine
PS
really in need for displacement

Great. Thank you for the info.
Re: World light always from the left?
With Cycles I get the attached result.
Even though the cracks look different, the shadow is also falling to the right, so I think the normalmap is not correct (or it is an optical illusion that only makes it appear as if a shadow was falling to the right).

BYOB
That's interesting. I'll try the scene with different Normal maps and see what happens.

Re: World light always from the left?
Just to say that I'm finding (as Kintux mentioned), that so long as the Gamma is kept at a value of 1 then the problem goes away.
I think I've seen an article about reasons for setting gamma values to 1 or 2.2 somewhere else, possibly on the older Luxrender forum. Sorry, but I can't remember where!
I hope the above make sense.
Cheers, and thank you both for your help.

Re: World light always from the left?
Do you mean you are using gamma correction on an image map used as normal map ? Uh, never, RGB values of a normal map are (X, Y, Z) values of a vector used to "perturbate" the shading normal. They are numbers, normal maps are just a simple trick for encoding data inside an image and, by using gamma correction, you are messing with them. You should never use gamma correction in a normal or a bump map.Racleborg wrote: ↑Sat Apr 14, 2018 11:07 am Just to say that I'm finding (as Kintux mentioned), that so long as the Gamma is kept at a value of 1 then the problem goes away.

Hi Dade
So is this setup incorrect and that the gamma should be set to 2.2? (file attached)
