Subject: Help with textures looking faded in P7

I'm new to P7 and the materials room.  I'm trying to use a PP texture (BillyT's WW suit) in P7.  When I render the colours look very faded on the suit.  Please see the attached image to see what I mean.

I was wondering if  this might be something relating to render or materials settings rather than the textures.  I just thought I would ask before I started editing the textures.

Many thanks in advance!

Given that a material shader can change the appearance of any color to any other color, the answer is yes.

Post a screen shot of the shader nodes in question and we can give a more specific answer. The number of ways this could be happening is infinite.

Hi bagginsbill,

I think this is the screen you wanted to see.  If not please let me know.

Thanks for your help!

Hi Booker5!

 

Ive tried the same costume and it renders fine for me in P7, both with Firefly and the P4 engine.

If I look at your material settings it differs some from mine, in Reflection_Image/Image_Source you miss a texture called ReflectCr that shall be in the BillyT/Reflection map.

Ah - well there ya go.

You didn't show what is in the Reflection_Image node, but if it is bright, there's the problem.

The Sphere_Map node uses the Normal (the direction the surface is facing) to look up a color from the Reflection_Image. That is then multiplied with the color in the Reflection_Color channel of the PoserSurface, and also multiplied with the Reflection_Value, which is .31746.

The color in Reflection_Color looks to be roughly RGB 156, 156, 156.In terms of brightness scaled from 0 to 1, this is about .61 i.e. 61%. Multiplied with the .31746 that gives .194211, or 19%. So 19% of the color in the Reflection_Image is being added to the render. This is easily enough to wash out the colors, unless the Reflection_Image is very very dark.

I have to wonder what the point of this is, since blue cloth panties do not reflect AT ALL. If they were blue metal panties, ok, but they're not.

You also have a pretty strong setup for Specular reflections, although with a highlight size of .02735, the speculars would be hot and tight - not smeared across the whole surface.

Do your panties shine? LOL Mine don't.

I'd disconnect the reflection stuff completely, and I'd probably get rid of the specular too.

Of course, if you're trying to make some of that outfit look metallic, then we'd want some specular and maybe some reflection, but that should be done with a reflection map to limit the effect to certain areas of the outfit. As it is now, the entire surface is programmed to behave unrealistically, neither a metal, nor a cloth.

Cross post and whoops! I didn't notice there IS NO IMAGE THERE.

That means the reflection_image is all white, so you're absolutely adding in a 19% gray to the whole thing.

I still think the reflections should be masked, even if you do load a proper environment map to the Reflection_Image.

Hi Bagginsbill!

They are super panties, they reflect anyway they want :-)
The settings are Billy-T's (the designer) default ones for the costume and it actually looks kinda nice when you render it.

Regards  / Jonny

P.s the texture is called RefletCr.jpg not reflect ( I wrote what I belived it to be)

Regards / Jonny

Thanks to Bagginsbill and jonnybode for your help.

I'm going to play with the settings you mention and see what happens. 

I obviously need to read up on the material room.

Cheers,
Paul
