Hi guys

Not sure if this has been covered over here,but here are my last woes with GC and Transparency maps

Here are attached the pictures of two renders,both has been rendered with same textures and same V4  and same light setup

This one has been rendered with GC on with no postwork

Second render has been rendered with GC off with no postwork

As you can see on the attached renders,there are differences with transparency maps on the Emotional II,textures are from R3D(Temptation for Emotional II http://www.renderosity.com/mod/bcs/temptation-for-emotional-ii/92897 ),this does happen with several other textures not only with those when you are using GC

I've tried to lower transparency to 0.4-0.5 or even lower,which doesn't helps at all 

Not sure what is best way to cure this or what is best way how to deal with those issues 

Thanks,Jura

If you are using Poser 10/PP2014, the latest SR is supposed to automatically correct the gamma for transparency maps. One can also use theChangeGamma script under MaterialMods on the Scripts menu; enter a value of 1.0 for all props and figures and "all of the above"...

Render settings should Always be with IDL and GC ON, and at 2.2

Color maps like diffuse textures loaded with "Render settings" or GC at 2.2

Black and white textures like transparancy, bump, and displacement maps, HAVE to be loaded in the material room at Gamma Correction set at 1.000

Hi WandW I'm using PP2014 with latest SR and those renders has been done in PP2014 and all trans maps have 1.0 what I know and what I've check'd last time when I've done those renders

But on other hand I've tried to postwork those GC renders and looks like adding more contrast will cure this issue,strange

Hi there I'm only rendering with IDL,GC 

Color maps are with GC 2.2 and all trans and bump maps are set 1.0

Thanks,Jura

Hi guys

Is possible something like contrast control per texture ?

Hopefully Bagginsbill knows how to control contrast 

Thanks,Jura

You can add a HSV node between the texture and the channel.

H = Hue
S = Saturation
V = Value

Or add a Color_Math node to increase or reduce contrast? 

Maths:Gain for contrast. AFAIK. 

BB might have a more correct solution.

Thanks that's worked pretty well Thanks,Jura

OK here are few renders 

First one is Sexy Dress II with R3D textures as you can see transparency are again over the place 

Here is same render but postworked with PS(I've adjusted only levels)

Third render and there I've plugged between the transparency map Math_Function ,set this to Gain and under Value_2 I've put 0.8 and transparency now looks like should 

Same above(3rd) render,but now has been postworked in PS(levels only)

Thanks,Jura
