Cant't get Full HDR image output.

Hi!

I'm trying without success - maybe I'm doing something wrong?

Simple scene - OctaneDayligt and Octane Camera - with 360 degree Spherical Projection.

Saving as HDR or EXR.

Saved image isn't Full High Dynamic Range - it's just flat like LDR.

How can I get real HDR output?

Maybe you didn'd disable the tone mapping ?

I'm attaching the scene, saved in MAX 2014.

Maybe someone would like to look at it.

I downloaded your file for a look. matttrebor is right.

Tone mapping is enabled in your scene. Disable it for full float image. (I also set gamma to 2.2 & linear)
a test image with your original settings and with tone mapping disabled. works fine only if tone mapping is not on.

OK!! Thank you!

I've managed to make it right!

There are 2 places where is "Tonemapping" option - in Kernel and in Camera -> Imaging tab - which is a little misleading.

Now everything is clear.

I've got another question related with this: Is there any way to get Full HDR image but with specific Camera response applied?

Is there a way to apply Camera response functions in Photoshop?
