clay is cool
what is color clay mode ?
can you please make that clay disregards specular materials with fake shadows which are windows so that in clay mode sun can shine through ?

SaveEXR tonemapped saves HDRI data
Are you sure? ... AFAIK the tonmapping respose curves are not defined out of display range, so all tonemapped images are clipped. To save a full HDRI image you need to enable the "Get full linear HDRI image" option.
In the Octane API we only have two ways of get the HDR image: tonemapped with camera response curves applied (with HDRI clipped, AFAIK), or tonemapped without camera response curves applied (full HDRI lineal imagen without clipping).

you can add the octane custom obeject plugin to the transparent objects to exclude them from the materials override and keep the specular material with fake shadows.

I am going to ask to the Octane developers about this. As I say before I think that camera response curves are only defined from 0.0 to 1.0 ranges, and this is why tonemapped HDR images are clamped. I am not sure how the Octane internal EXR saver can save tonemapped HDR images without this clamping.
