These days I would recommend ACES. Otherwise, you will need to do massive color correction afterwards to get a reasonably pleasing rendering from linear HDR data, and that's not ideal from a precision point of view. Or, worse, you will be tuning your assets/lighting to look good under the bad tone curve, which is a fool's errand - you will not get the correct look in varying lighting conditions, because your inputs are no longer physically based (ex: dark albedos are too dark, etc). IMO, the only thing that's "physically based" is emulating what cameras do, which is to map linear HDR sensor data to an LDR screen or print using an S shaped response curve. This is the same for film and digital media, so it should work equally well for rendering. <br /><br />The most basic test is that a properly captured linear HDR environment map of the real world should look pleasing when rendered through your engine, roughly what a jpeg photo or mpeg video of the same environment would look like as it comes out of the camera. Under Reinhard, it will look like washed out garbage.<br /><br />Sadly, almost all software packages use a linear tone curve by default, to this day, which is an atrocity of global proportions!Steve Mhttps://www.blogger.com/profile/15869000009442253486noreply@blogger.com
