I downloaded the file for the studio lighting tutorial (https://docs.arnoldrenderer.com/display/A5AF3DSUG/Studio+Lighting). When I render it the sphere looks completely different to that in the tutorial. I didn't change anything (and the tutorial doesn't say anything either about making any chances regarding material...) What am I doing wrong?
I've updated it now. Try downloading it again. You will have to use your own HDR maps though.
Thanks for your reply! I'm afraid I can't open the file since I use the 2020 version...I should have mentioned that.
This is actually how it looks like. I didn't use any HDR maps but only quad lights. It seems to me that it could a material issue since my sphere doesn't look as metallic as yours (and the environment reflection is black instead of grey)
