I understand in order to have the final render match the live preview that the OctaneImager has to me checked on for the render. Is it possible to show a non-tonemapped image in the live render window? Basically having the live viewer match the output of the final render with the OctaneImager set to off for final render.

Thanks

1. To match the live render view and final render you need to disable Blender's color management by going to "Color management" settings and set the "Display device" to "none" Im assuming that Octane Imager is turned On .
2. If you want to show non-tonemapped image in the live render window you need to disable Octane imager and disable Blenders color management. Unfortunatelly this is buggy and final render is not the same as in live view.

As a rabid E-Cycles convert/lover, I am only mildly interested in Octane Blender 2.8, but I just went through the trouble of downloading Blender_Octane_Edition_2019.1.RC3_18.3_beta.exe
from my downloads page, and it appears to be for 2.79!.... So let me get this right; you finally release Octane Blender 2.8, and it is just the freebie version that is limited to one GPU, and
you have not bothered yet to make a version (for us paying customers that have been waiting eons!) with normal GPU limitations in my account download page? WTF? Things are looking
worse and worse for your prospects of me renewing my enterprise sub this winter...

Hi J.C.

I had the Color Management set properly and the Octane Imager was disabled but I wasn't getting the same results as 2.79 / V4 so figured it may have been a different procedure for 2.80 / V2019. It is an early beta so I just have to be patient.

Thanks again,

I launched the OctaneServer.exe and got some errors. See screen capture. Any ideas what this is?

So, is this only limited to 1 GPU. On the machine I'm testing it on, I have two 780ti but only one can be checked.

Also, how do you use an hdr image for the environment?

Thanks for the help in advance.

Hi there,

You are likely trying to run multiple instances of OctaneServer.exe at the same time, please check the taskbar for an Octane logo.

So, is this only limited to 1 GPU. On the machine I'm testing it on, I have two 780ti but the only one can be checked.

- 1 GPU is Prime limitation

Also, how do you use an hdr image for the environment?

- Could you please try to connect a texture node to the texture env

cheers

Mine also didn't work and had empty render. After updating nvidia drivers it works.

Hello, suvakas,

I've tried to reproduce but with no success. Could you please share me a sample? Thanks.

Cheers,

This might be because there is white emission enabled for environment by default. To disable this you need to create texture environment and set color to black.
Dear developers, please turn this off by default. The empty scene should have no light.

I'm using ACES workflow with ACES 1.0.3 OCIO config (not the one shipped with blender by default), and it seems that it doesn't let any value to go above 1 in linear space (I'm already set the octane camera imager to linear/off), so the highlight is compressed, even when I'm saving it as an EXR file.

The colour response, Shadow and Midtone value are already accurate/similar with Blender Cycles+ACES config, it only affects the highlight so I guess it is related to Octane tonemapper / imager. And CMIIW, the data flow is: Rendered scene > Octane Imager > Blender OCIO, that's why it only affecting value above 1 in the output file, and it will always be like that whether the Camera Imager is turned on/off.

It is possible in plugin for 2.79. There is a checkbox "Prefer tonemap if applicable" that totally disables/enables Octane tonemapping. I can't find this in 2.8. Maybe turning off Octane imager from camera tab does this automatically?

If you use Octane Imager settings from 3d view and want the same settings in final render make sure the "Override" option is enabled.
