APG 3.0 - problem getting an HDR result

We just updated to APG 3 and everything is much better than previous versions, we love using it.  But then it comes time to render, and it is proving frustratingly difficult to get the same types of results we got in 2.x

We have spherical panoramas shot in bracketed exposure stacks, and want a single HDR non tone-mapped result. No matter what I try, the result always comes out LDR with tone mapping baked in to the pixels.

What is the process for properly creating an .exr or .hdr file that has zero tone-mapping applied to it and has a true HDR range? The color settings have moved and changed since the last version, so I wonder if the process for creating HDR spheres has changed too?

Hi Andy!

When you do spheres to get HDR probes for IBL or GL you can work with stacks in APG and put them out as .hdr/.exr - but NEVER use color-settings in this process.
That´s because colorsettings will be done later either by tone-mapping/compressing or in the IBL process using dedicated applications like HDR-Light Studio or so.

best, Klaus

You need to render a -hdr/.exr file:
