Title: What I see on RFW is not I get from saving the file
Post by: modular on 2021-11-02, 23:32:41

Hello! Need some help here...

Let me try to be as concise as possible. The image result I get when rendering a scene on 'Rendered Frame Window' is completely different from the one I get when I save the file directly from there. I mean, if I copy the image from RFW and paste it on Photoshop, it is perfect. When I save from RFW (or batch render) as a .JPG, it gets all messed up in the colours (everything looks burned and super bright).

What can I do to fix this? What I get on RFW is spot-on for what I need.


Here's a quick 2 minute "almost rendering" for you to have an idea of what is happening:

I'm getting a bit desperate here. I have dozens of renders to batch and I can't go one by one copy-pasting the image to Photoshop. It will take me days to finish this work.


Any help will be greatly appreciated!

Thank you!


EDIT: I'm using 3DSMax 2018 + Corona 6 (Hotfix 1)

Hello,

It looks like gamma is applied twice to JPG file, no ?
Try to force save file with gamma 1.0: in mxs listener, type FileOutputGamma = 1.0, and then hit Enter.
Or you can try to output as EXR, loading the files with Exr-IO free Photoshop plugin.

Clueless about that.

I will try that. If it doesn't work how can I revert that code line?

When I save as EXR and try to open with Corona Image Editor I still get those super bright images. Will this get fixed if I install that Photoshop plugin?


Thank you!

Are you using lightmix? Maybe waht you see in the VFB is lightmix layer, but what you're saving to disk is regular beauty layer?

First of all check 3ds Max gamma settings:

Customize -> Preferences -> Gamma and LUT:

Gamma 2.2 and both checkboxes at "Material and Color" should be activated.


Good Luck

Hello!

I'm a bit clueless here because I'm just using Corona for a couple of months now. Let me screenshot what's happening and my setup. Maybe it's easier that way. Here's the images:

Hello,

Could you please share the scene, or even a simpler scene that reproduces the problem (File menu ->Archive) ?

I had the same iussue in some old files, you can try:
1) merge the file in a new scene
alternatively
2) save override 1.0 or 2.2, try both.
