Environment Tag HDR issue Tweet

[thanulee]

Hi, I am testing some of my HDR collection and i see that i dont get the expected results. I get really bright areas and no consistency on how hdr was supposed to light the scene.
If i uncheck importance sampling, it gives me a very dull result and if its on a very bright. I have to lower the hdr power to values like 0.001 in order to avoid overbright areas and still the light doesnt correspond to the environment. I got a very dark env and a whatever light that just doesnt burn out everything. Im using 3.07.0 test6a as im testing this.

I have tested the same hdrs many times in Vray and in production with no problems.

I attach a scene and some images to demonstrate the issue cause idk if i describe it correct. This thing happens with the majority of my hdrs btw.

Find gamma of imagetexture and play wit it.

Cool, thanks, changing it to linear seems to load the hdr correct. There was a more obvious switch with gamma if i remember correctly, its been replaced with this menu?

Another question though, why when i change the settings there, hdr doesnt get affected? see images
Cheers!

You're using that wrong! Why don't you use ImageTexture, not XBitmap?

Mmmm what do i do wrong? I am adding an octane hdr sky and i load the texture in there. Is there another way?

[thanulee]

Oh ok i figured that out. I m using HDR link from GSG and it doesnt work as expected and replaces the image texture. I should just re add it manually!
Thanks for the help!

HDRI Link works great when setup properly, here is the setup for octane

For some reason doesnt let me drag it to "file" and only to "texture". Idk why is that. Thanks for the help anyways.
