Question/Problem with lighting

Question/Problem with lighting was created by caffrey75
Hi,
I'm not sure if I've always been having this problem, or if it's just cropped up over the last few weeks or something, but I'm having real problem with Solid Rocks and lighting. I'm rubbish at VRay and hopeless with technical terms (hell, that's I why I bought SR ), but SR just seems to ignore my lights, my shadows....or something. I noticed it the other day when I was working with buildings. Although there were no lights shining into the building and it should have been in shadow, the inside was still being illuminated and no matter how I fiddled around with my lights I couldn't get it to change.
Anyway, I've posted an image which should hopefully illustrate what I'm talking about. I don't think the scene could be more basic really, as far as I'm aware SR is using default settings, and there is only one VRay light in the scene, shining directly down on the Mannequin. One image has been rendered with normal VRay (1.50.SP4a) and the other with SR. Although there are shadows in the SR render, it's all sort of overexposed/lacking depth.
Sorry for my crap technical understanding, hope you can help (I'm using SR 0.98.9 btw).

Hi, still can't work out what's going on with this, even with the new version. Any help or advice would really be appreciated. Solid Rocks just seems to want to flood light through my whole scene, even areas that shouldn't be affected by light and just sort of burns all my shadows away....

Hi, i'm sorry for delay i've taken some holidays and looks like i missed your post when back.
First of all, just to clarify : SR never creates any lights. So i guess it's basically a gamma problem.
don't know if you're using gamma correction into SR. But for testing, the very first thing to do is to uncheck it, or, if not correct, activate it with a 1.0 value to check if the result is correct
Please tell me what's happening after this tests, i'm sure we'll find a way

Oh my god! That did it, setting the gamma to 1.0. At least, I think it did it - the light is now as it should be. I actually feel like a bit of an arse that I never thought to turn gamma down, it was on something like 2.5 all along and I overlooked this
Thank you so much, Jérôme! Solid Rocks really is the King of Vray Plugins
Just one thing, and I'm a little embarrassed to be asking, since I'm sure the solution is probably equally as simple. In trying to fix the above problem, I've screwed around with my SR settings so much that other things are not looking as they should (for example the scene now has a pink hue to it) and if I try a render using Col.Map set to Reinhard (which I think is the default), the scene is all black. I think part of the reason might be that I applied SR optimisations to my Materials and Lights in my frustration before. My own stupid fault, but is there a way of removing ALL Solid Rocks optimisations to a scene and starting again (knowing what I know now) or will I have to redo maps etc by hand?
EDIT: sorry, I fixed the pink hue easily enough by doing an Automatic White Balance, but am still interested in knowing if there is a 'Restore To Default Factory Settings' button that will reset all the buttons I unknowingly clicked when I shouldn't duh.
EDIT EDIT: I just fixed the Reinhard issue too hehe
Thank you again, Jérôme!

Many thanks for your kind words !
i'm pleased to know that AWB tool solved your pink problem.
note : any question is NEVER stupid
SR only affects the subdivs values of materials and shadows.
One thing you can do is to "apply" the settings permanently to your scene, this will put all your materials an lights subdivs to the default value (generally 7 or 8, see the edit preset button, global values section)
To do this, just go into the init/save panel and click on "apply optimisations to scene" for materials and/or lights.
If you want to apply All solidrocks settings (Vray settings) to your scene, then check ON the "apply solidrocks settings on exit" then close SR. all Vray parameters will be permanently modified by solidrocks ones.
Hope it helps !

Hehe, granted, I say the same sort of thing when I'm teaching people how to use Flash, but because I'd searched so hard and could find noone who had the same problem, I figured that I must be making a really simple error - which I was
Thanks for the info about resetting SR, despite saying that I'd 'fixed' it, Reinhard Color Map still kept rendering out a black scene, no matter what I tried. I must have been dreaming when I said I fixed it before. Not sure what the problem was, but no matter, because I just created a new scene and transferred everything over and it all looks great - problem solved.
All the best, keep up the good work
