Thank you !

Downloaded all without problems.
Please take a look and follow this link: HDRI Environments

for all those photoworks converts dont forget all the old HDR data that came with the old installs.

hy and thanks clearly the beauty of this program is the realistic look into an environment, without tomany setting, but clearly keyshot need to provide more 360 FREE  ;) hdr environment... like may other engline programs supply materials preset etc.. thankstef and great easy program!

Some of these have a JPEG which I assume is a 'backplate' image and they often come with two hdr files - an '_Env.hdr' and a '_Ref.hdr' which is usually much bigger file size. What's the difference in the two hdr files please??

Robert V.

The bigger one is high-res, and results in sharp reflections. It can also be used for a render without a backplate.
+ Gives exact reflections
- Renders slower

The smaller one gives the correct lightening,
+ it renders faster
- no "real reflections"

@PredatorKS - I don't think that HDR size has an effect on render performance once it is loaded.

Robert V.

@Thomas,

That could be true, I haven't experienced it myself, but I read it somewhere else...

guest84672

Yeah, maybe in other software ;-) - we will test it though.

Many of the renderers out there now support multiple resolutions of HDRI. Please check out sIBL:

The idea is you can use a low-rez hdri for for lighting, a middle-rez for reflections, and a hi-rez one for backgrounds, unless you are using a backplate.

sIBL has some really good tools for creating all of these HDRI's from a single image. On the site, they say how much faster a render will finish if it uses low-rez lighting maps.

Your comment about speeding up when using low res maps for lighting does only apply to slow tools like mental ray, most near realtime engines do not need such tricks ... no need for sIBL.
