Which DS Render Settings to get the same effect as in Blender?

Hi! I created a HDRI with Vue, and when I load it into Blender (as well Cycle as Eevee), I get exactly what I want. However, in DS, it's much too bright, it's so bright that it becomes difficult to see some part of the HDRI. I tried to fix it by changing the tone mapping and environnement seetings (especially the exposure value, the evironnement map strenght en the environnment intensity), and I could improve it, but I couldn't obtain exactly the same effect as in Blender.

In Blender, I just loaded my HDRI without changing anything to the default settings. So, I would like to ask you some advice: is there "a trick" or some strategic values to use in DS to get the same effect as in Blender? Thank you in advance!

    In which format you have this HDRI?

    I have quickly tested opening HDRI file in .EXR format in Daz Studio and it works ok.

    I would suggest to use any of HDRIs created for Daz Studio as a base and just open your own file in Environment Map

    in Environment Options.

    I have used as a base:

    The render with one of the maps included in it:


    The other render with .EXR map replaced:

    Another example, with different .EXR file:

    Thank you very much! I am using a .0hdr format because I got some transparency issues when I tried to create my HDRI into a .exr format (I didn't understand why). To import my HDRI into DS, I simply started from the default Ruins HDRI, that automatically appears when I compute a render without environnement in my scene:

     

    Then, I loaded my .hdr file into the the environnement map.

    I alreadu did that for HDRI that I bought on Renderosity (for example: the Milkyway HDRI (https://www.renderosity.com/marketplace/products/156095/milky-way-16k-hdris) and also the 2 MOUNTAIN HDRI (https://www.renderosity.com/freestuff/items/83244/2-mountain-hdri)), and I never got any brightness issue. Just for the first mountain of the 2 MOUNTAIN HDRI, I needed to decrease the environnement map strength to 1 rather tha 2, but beside that, I didn't need to change anything.

    However, for the HDRI that I created with Vue, the Ruins HDRI settings don't work; here is a comparison of what I obtain in Blender and in DS with the Ruins HDRI settings:

    By changing the environnemnt map strength and the tone mapping, I could improve that a little bit, but I'd never got the same effect as in Blender... Could it be due to the fact that I use Vue to create my HDRI? Since t's a HDRI, I turned off the Vue ray tracing and tone mapping to create it. I also tried with the Vue tone mapping turned on, but there is still this brightness issue...

    On another hand, since it's a desert, it maybe normal for the environnement to be bright, but since the effect is completly different in Blender, I wonder if I made a mistake somewhere...

    Blender uses different render engines than iray, so it is not so easy to get the same results.

    Have you tried to play with Tonemapper Options in Daz Studio?

    You can adjust brightness and the other parameters there.

    I did it from the Render Settings pane, but yes, it improved to result, but I'd never got the same effect as in Blender. Since it's the first time that I create a HDRI, it's difficult to know if it's just normal due to the difference Daz/Blender or if I made an error when I created my HDRI... Especially because I didn't find any tutorial explaining how to process...

    Maybe try to figure out how to export EXR files from Blender:
