I'm having an issue with the final output of my render. Everything looks great in the Live Viewer and the Picture Viewer but once I open the .tiff or PSD, the image is incredibly blown out. It's not something I can fix in the image editing software as the blown out pixels are actually blown out to the point of lost pixel data. I've never had this issue before but now it seems to happening with every render. What am I missing?

I've been having a similar issue lately as well. It seems pretty intermittent and it's been very difficult for me to nail down what change seems to be causing the issue in a given file. I will also say that I was talking to another motion designer today who said he's having the exact same issues. Both of us have sometimes found copying all our elements into a new project seems to solve it but it doesn't help me understand what I could have accidentally changed to cause the issue to arise. To put into perspective, I'm pretty consistently using the same settings on all my projects so it's unclear what would be different in starting a new file. And more importantly why the live viewer would show something correctly that then would render incorrectly.

FYI on all my machines I'm running 2020.2.5 because I was having some issues with 2021 and downgraded back.

You should use same color space when you import images. Otherwise it will be different than LV or PV.

I'm not sure what exactly you're referring to. Whenever I import an image texture or an HDRI I don't change any color space settings. (Not in the project or in the image texture node itself). Is it something specific to the file being imported?

It's clear enough. You should use a similar color space in pshop what you're using to view in plugin's interfaces. I'm not using pshop btw.

I can't speak to Shane's situation but look at this on my end:

This is Twister D v4 straight out of octane. This is Twister D v6 straight out of octane. On my end those look very different regardless of whether they're in photoshop or after effects or preview or whatever.

And to clarify, both files have octane settings set to SRGB (and the C4D project settings are also both set to SRGB & Linear Workflow).

Here's a link to both files if it's helpful:

And to further complicate things here's the same project rendered out of my laptop instead of my desktop. Same exact project but different result.

This is not a case I can help you, because it's not a plugin related issue. Better to talk with support team for learning how to set your color management pipeline.

I'm not sure how you can say for sure it's not a plug-in issue. We're talking the same file produces different images just by rendering the exact same file on a different computer. It's clearly not as you initially suggested that the problem is in the Photoshop settings, because as you can see these are just PNGs straight out of octane and uploaded directly to this site. So I'm not quite sure where the "pipeline" is that you're referring to. The file comes out of octane one way on one computer, and a different way on a different computer with all the same settings. Then it gets posted straight to this forum. So there's no real pipeline here. It came straight out of octane and then got posted here.

This is an issue that's only popped up somewhat recently (within the last 4 months) so maybe it's something that's related to R25? Or a new Nvidia driver? I'd just be hesitant to so quickly dismiss it as not related at least in some ways to the plug in.

Hello @Ryanscammel,
I'm saying because I know what we did as a developer. You are asking something not our mistake or something needs to be fixed. Any devs has not to spend their work time on finding and fixing user mistakes. We have support team for helping you if you cannot find and learn the usages. I'm answering some posts if it's quick to help. I'm being away if something is time consuming. Hope it's clear, regards!

Your problem is multipass is enabled.

A standard c4d/octane render will render out to the regular old srgb colour space until you start changing settings. When you enable multipass though, c4d must switch its output system to linear output, because compositing all those layers together in srgb space is impossible, only linear works. Your V4 file has multipass enabled, your V6 file has it disabled, so they are rendering the same thing, theyre just putting it and thus showing it in completely difference colour spaces.

enable multipass / Render AOV to make the v6 file brighter, or disable it in the V4 file to darken it down like the v6 file.

Technically your V6 file is correct, but obviously do whatever works for you.
