Sorry you haven't got this working yet.  As you say, opening a support tciket can do no harm.

I plan to create a replacement set of "Move Down" presets (sadly, the originals are compressed, so cannot just be edited).  If I do this, I'll post the presets here so that anyone can use them.

Thanks - I have it working now and I've made a set if test renders to demonstrate the issue which I’ll use on the report as well as referencking your thoughts on this breaking as a consequence of an upgrade.

I might also create some presets at some point, and I’ll post them here assuming you don't beat me to it.

Thanks once more :)

Here is an alternative set of "Move Down" presets for ColorWerks.

Hopefully, there will be an official fix at some point.  Until then, I find that I get better results with this set than the ones bundled with the product.

This product has always worked as intended for me. I believe it only works on trans-mapped hair, so if you're trying to use it on strand-based hair or dForce hair, then that's likely your problem. 

I've attached an image that demonstrates the issue.

Both renders were done in DS 4.15.  The hair is OOT Clasic Bob.  This is a standard trans-mapped hair with uv maps that are non-reversed and are well designed to support horizontal hair blend transitions.  The base colour was set to brown and the overlay colour to purple.

The portrait on the right uses the "Colorwerks Offset Vertical 6" to set the position of the horizontal blend transition.  This sets the vertical offset of the masks instance tiling to 0.2.  There are two clear issues: the overlay colour is applying to the roots of the hair rather than the tips, and the transition is sharp with no blending.  The other offset presets allow the value to be set in the range of 0.1 to 0.5.

For the portrait on the left, I manually set the vertical offset of the masks to 0.8.  This rectifies both issues and I believe that this is how the product should work.

I also have the sister product to this one, ColorWerksX.  When DS 4.12 was introduced, I noticed that portraits that worked correctly in DS 4.11 rendered with the overlay color applied to the roots rather than the tips of the hair.  ColorWerksX uses a custom shader, but now I think that both use the same underlying method to control the mask positions and that both products have been broken since the introduction of DS 4.12.

(Correction: looking at Colorwerks X today, it appears that the problem may have been fixed since I last used it).

 

Completely OT I know, but @galien, would you tell me which lighting setup you've been using in your example pics? I just love it, makes the skin so soft and alive-looking! Thanks!

I used a single light combined with an HDRI.

The light is the soft key light from Ultra IRay Ambience.  This has just been angled a little to the side.

The HDRI is the saturated gold one from Perfect Portrait Lights.

This is how the blends are supposed to work, but this is not what I see. I see the portrait on the right.
 

I'm not entirely clear which portrait on the right you mean (mine or the promo image).

I used blend mask 3 for my portraits, but it would probably have been better if I had used mask 22 (which is the one that I think the promo image uses).  I don't have the hair used in the promos, but I tested which values are required (for the tiling vertical offset) to reproduce the effects in the promo image.  The results were 0.95 for the leftmost one decreasing to 0.65 for the rightmost one.  The values actually set by the built-in presets are, from left to right, 0.45 to 0.15.  A value of 1.0, gives a blend for the full length of the hair (for any blend mask other than mask 22).

I have attached a render with the values set to 0.65.

Yes, sorry, that wasn't at all clear. I see exactly what you see, I meant your portrait on the right. I tried 5 styles from different PAs and same every time.

I'll also be reporting this as I don'

t see that harm it can do. Thanks again for your help.

Yes, the product is broken.
Yes, the original vertical offsets are compressed, but all you have to do is uncompress them with something like 7zip. They are compressed, but not encrypted. Once you uncompress them, you can edit them with any text editor.
Thank you for posting your offset correction files. I think I will use them as a basis for correcting the originals.

Thanks for posting this, barbult.  I didn't know that Daz Studio compressed files could be unpacked with 7zip.

@galien I used your techniques to modify all of the vertical offset files and all of the mask files. Now I can load a mask and it works correctly without having to apply the fixed neutral vertical offset afterwards. Ah, it is so nice to have a working product again! Thank you again for posting the solution. It would be nice if Daz or Slosh would issue an update to fix this for everyone.

It works perfectly! Thank you very much! :-D

Can we use that product on strand-based hair ? Or I must use ColorWerks Extreme ? I don't see the difference of these 2 products.

Or another product for realistic colors of strand-based hair ?
