Victoria 7 Reflection/Roughness Maps don't fit!?

I was very eager to start using Victoria 7 after the long time I've tinkered around with the Genesis 3 Base Model, but soon I've noticed some problems with the reflection/roughness map of Vicki. I couldn't explain first until I deleted all surfaces and build it up setting one map after another. I've redownloaded Vicki and unpacked and placed all parts of her manually to make sure there was no bug while installing in the Smart Content System or with DIM Installer, but without any change. Finally I've replaced the torso and the leg reflection map with Jeanne's (slightly modified) and now it worked.
The thing is, I've seen many Victoria 7 renderings which doesn't have the problem I get so, is there anyone out there who can help me out here?
There is a little pic attached to this post that shows two renderings one with the original reflection map from victoria 7 and one with the one from Jeanne.

In my experience, the problems aren't with DIM. I used DIM with V7 and never have these issues. You do of course need to make sure that the content paths in both Studo and DIM are the same.
Open the legs reflection texture in the image editor (not Layered Image Editor) and check the map's set to a gamma of 1, or at least make sure the gamma's the same as the torso reflection texture.
And do the same for the roughness texture.
How are you loading/applying Victoria 7?
Oh so nice, I didn't have my hopes up to get a quick solution for my problem so fast. Gamma value of the legs reflection map was set to 0 (beside others), while torso was set to 1. A quick test-render already produced a nice seemless reflection. Thanks for the help!
First from the Smart Content Section, afterwards from the Content Library (using DIM Installer to install Vicki 7), and as geometry with the textures selected in the file browser of the surface editor.
Thanks a lot for stopping by and answering me!
Good to see it was a simple fix. It's the first thing I do when I see a mismatch these days. I wish Daz and the content creators would check this stuff, as it puts a lot of buyers off (another user just said they won't buy anything G3F from now on) and makes setting up a figure a bit of a PITA. If it's a scalar value driving a weighting surface effect (roughness, glossiness, translucency weight, specular, etc) then the gamma should always be 1 to drive a linear multiplication, as far as I can tell. An rgb map driving colour should be 0, or match whatever iray is set to in the render tonemapping gamma value.
PS, I think some content creators adjust their weightmaps to an embedded profile of 1, but either miss some or iray has a bug. I've often been told that as long as the texture has that embedded then all should be fine, but I'm convinced Daz iray doesn't always obey them (they work sometimes and soemtimes don't) and the people giving the advice haven't actually tried it for themselves.
yeah I am still seeing a lot of rgb grayscale maps and not proper converted grayscale and there lies the problem I think.
I really mean were you loading the figure with the character preset, or applying a materials preset to an already loaded figure, or did you try both? Anyway, mismatched gamma settings should certainly be reported as a bug.
Do you guys really think that there is an issue with Victoria 7 and it hasn't been reported / fixed by now? The OP said Victoria 7 / Jeanne, not some other PA product.
If they weren't RGB instead of proper greyscale maps, then it wouldn't matter if the gamma is set to 'guess based on what the 'header' data in the file says it is' (0) and 'don't do anything' (1).
Loaded the whole character from the people section. Afterwards I was applying the skins from the material section.
I consider this more of a problem of me being new to DAZ/Iray and the navigation to many functions and settings, which is very confusing to me. it's bad to hear that buyers are getting angry, but on the other hand I couldn't say any other source for such a wide variety of humanoid models at this low price.
LOL I think I agree with that. :)
There are a couple of PAs Im cautious about buying; one PA I have 4 (yes four) figures in query; all have confirmed issues, that aren't the usual easy fixes.
I'd return em but I missed it by a couple of months. There are two/three reasons (depending on how one catagorieses them) I'm buying less from Daz, and this is the other, or one of em.
I'm still buying at all becuase some PAs have upped their game; they were already just fine, but they are giving more options. Just stating this as not all PAs are the same, some are amazingly good, as artists and with the quality control.
I still don't understand the problem. The attached image is Vickie 7 with the IRay All Mat skin. Render Studio Pro HDR for lighting.
What exactly is the problem?
