hdri on a sphere as sky object?

Hi All,

I'm trying to do a camera animation with an HDRI on a sky object but when the camera moves the HDRI BG moves weirdly because it is an infinite object (when I dolly the camera the BG doesn't move but if I tilt it moves too much)

Is there a way of using a sphere that is only slightly bigger than my environment so the HDRI background moves correctly? With just a little parralax?

Cheers!

hi, i would try in this way:
set an octane environment to black, so it doesn't interfered with the illumination;
create a big sphere with reversed normals and give it a diffuse material with, in the texture emission channel, the hdri;
you surely need to play a lot with the power and the gamma of the hdri and the general exposer in order to get the right illumination, but it surely works ;)
