Scattering node slider issue

Hey, I'm quite new so forgive me if I seem silly.

I've been messing with this plugin and some materials from the DB. I've noticed that people on this forum have been setting the Density (previously Scale) slider for Scattering nodes to values over 1000. My slider says it has an upper bound of 10000. However, it only reaches 1000. Some of the skin shaders I've tried out definitely seem like they need more than 1000 to look correct. I can't seem to find an obvious way to increase the upper bound.

I'm running R3.8.0.38 Subscription.
I really appreciate any advise on the issue.

Here's an image. You can see Density says it has an upper bound of 10000, but the slider all the way to the right only goes to 1000.

Hello dmango

Some sliders are limited to those ranges of values that are most useful for the specific variable.

If a wider range is possible you can always enter numberic values manually by:

- clicking on the number entry field with the mouse
- enter any number in the possible range with the keyboard
- click enter on the keyboard

-> now the preview screen should update

- - -

Density is a variable where in most cases you will notice a difference by using very small numbers.
like 0.1, 0.5, 1, 5 etc. 1000 is already very dense. With 5000 or 10'000 you may not see a difference at all.
Density 0.1
Density 0.1
Density 1
Density 1
Density 100
Density 100
Density 5000
Density 5000





Hope this helps you get started.

I really appreciate the detailed response! Apparently the plugin was bugging out on me before because I was unable to manually change the values. Trust me, it was the first thing I tried.

Restarted DAZ fresh and it worked for about 5 minutes, then I couldn't manually change anything anymore. So I closed the nodegraph editor and the octane tab and afterwards it worked when I tried again. When it's not working, I can click the box, the existing value gets highlighted and if I type a number, nothing changes.

Most skin shaders I've tried definitely don't need high density values, but one popular one called tonysculptor only looks correct now that I've cranked the density way up. I'm just following the advise of other posts I've read on this forum. But in this specific case it seems to make a big difference. Guess I'll need to properly learn how everything works so I can figure out why it makes a difference in this case.

Thanks so much for the help.

I have had this happen too. It seems to be a Qt or DazStudio bug, where the mouse clicks are being sent to the wrong window, but it's never something I could reliably reproduce to investigate.
