Thanks RRIS.
So I have to check this setting on Keyshot.
So if I have mm in Rhino and mm in Keyshot I have no problems. (because sometime, I don't understand increase time of render).
for example, I've a 3d urban furniture, so sometimes they are products with a height of 1000mm, so I don't know if it's better to leave them in real scale or reduce the scale to make the render.
This is another dilemma for me.
But do the HDRI images automatically adapt to the unit of measure set on Keyshot, or do they have a setting of their own?
Thanks again
Doesn't really matter, depends on the accuracy you want to work in.
I usually work either in mm's for anything up to car-size.
As long as you use the same units in Keyshot (edit > set scene units) there's no problem.
