Click the browse button and
locate a HDRI you downloaded
from my web site. All these
HDRI maps are in ‘mirrored
ball’ format. So check the mir-
rored ball option in the HDRI
parameters.
Many free HDRI maps are
unwrapped (they look like an
unwrapped globe), you need to
set the type to spherical envi-
ronment for these map types.
Some are ‘angular maps’ (light
probes, like the old HDRI’s on
Devbec’s website), so check
angular map if you’re using one
of those.
