In a render or draw? Iray, 3delight, Filament, OpenGL?
iray, setting up a render
If Iray is active in the Viewport you should, in theory, just click the exposure meter icon (the +/- icon next to the drawstyle button) and then click in the Viewport (the area being rendered, that is) to set the white point - though I always seem to get it wrong (but I had the same issue in Photoshop, so that is probably a persistent grasp of the wrong end of the stick).
Hello Richard,
that seems to do something to exposure level (and not good in this case) but nothing to white point, any other ideas?
Not sure if that is what you are after.
But in Render Settings > Tone Mapping, you have White Point, whhere you can set the color of what you consider white.
Hi Fells, thanks, and yes, I have tried that, I can get an acceptable result that way after a dozen adjustments, but its not precise, and it is tedious.
There has, surely, got to be a one click way of doing this.
If you try zeroing Saturation, the object should be purely white.
Have you tried setting viewport in Iray preview.
And then hoover over White Point color bar. Press and hold <Shift> and move your cursor out on the cube and then release <Shift>?
hello Felis, this is changing the exposure, but not the white point
but that makes everything white
That's the only way to make a 100% pure white, and you can easily render with Canvases and merge them together with post work. It's a commonly-used technique...
Or... you don't have to do so in DS, tweaking all of them as you wish with post-work would be also a doable way...
Yes, however I am trying to set the white point
What Felis says is per the onscreen instructions, but it does not work as it says it will;- it does change the exposure (completely wrongly) but ir does NOT touch the white point.
There's no White Point adjustment for preview within Viewport but only a White Balance auto-adj. With Iray drawstyel, Draw Settings pane, Advanced tab, turn on White Balance.
What are yiou trying to do? Achieve white, or achieve a neutral grey (but not blown out to white)?
Hello Richard, setting the white point/balance, as the picture looks wrong, far too orange in this case.
When working on a photo which has this problem, I would most often select the white of the persons eye, or some other reliably white/true grey object, and the colour of the whole photo then looks good.
Momma Photography says;-
So you are wanting to eliminate a colour cast. I am not aware of a tool that will auto-adjust for that, sadly.
Yes, colour cast, you surprise me that there is no tool, I can always post process the pictures I guess
As Richard said, there's no tool in DS for such an auto-adjustment. Rendering is not like photography with photosensitive elements (CMOS/CCD) as well as light and white balance metering, etc.... Render results mostly come from the scene setup and render settings.
For instance, the light temperature, as shown in your 1st screenshot. If you want to have the result in the 2nd screenshot, just adjust the lighing pattern by increasing light Temperature, as well as settings in Tone Mapping even Environment Tint with exterior or interior HDR. You can easily make it work.
Certainly it's also easy to tweak the render results with post-work. I personally prefer to this way.
Thanks for help

As @crosswind said
Draw Settings pane, Advanced tab, turn on White Balance. Then you can use the widget in the viewport.
I knew I had used this before and had completely forgot about it, but it works :)
The best way to fix this problem in DAZ Studio is to change the room light and make it white (6500K) before you render. Then everything in the room will be the correct color.
