I've been trying to make an HDR render to be used as background and IBL in Carrara - after what seems to be a reasonable time for the render, all I get is either a pure black or black with stripes image - I use HDR View to see the HDR.
I've tried with the 360 panoramic view as well as perspective projection, with the same result.
My process is to set the document size - ideally this would be 8000 X 400, but any size gives the same non-result. Then select either panoramic or 360, then render to disc. I'm testing on preset scenes, so have not made any camera or lighting adjustments.
Are there perhaps other settings that must be dealt with to get a result?
On some related issues - if I set a reasonably largish document size, the controls on the right of the screen are overridden, so can't pan and zoom.
Also noticed that the option to save as HDR probe is greyed out - this isn't used in Carrara, but is it not the type of HDR that is used in Bryce for IBL?
Any assistance will be greatly appreciated:)
