Just finished this.

Please, check the original size if you have the chance, I like how the detail turned out. tongue laugh

WoW! hellboy! just…...wow!  looks like a bronze statue. How many samples did you render it too?

Just got this render out of the oven smile

Not nearly as good as the renders already posted here, but it’s my first render using Luxus that I thought was worth sharing. Due to the transparency of here dress, I couldn’t post the full image here. If your interested in seeing the full image, you can see it in my Rendo gallery here (warning nudity):
http://www.renderosity.com/mod/gallery/index.php?image_id=2437740

Now I just need the time to be able to play with the beta Luxus plugin for Carrara!!!

It is time It is time to explain the Javascripting in the Extra settings.  The simplest application is using Lbm2(LuxRender Material Database) files.  Here is a lbm2 file saved out of Blender.  It is a very simple matte material which is a shade of gray.

{
  
"_comment""LBM2 material data saved by LuxBlend25"
  
"objects"[
    {
      
"type""MakeNamedMaterial"
      
"extra_tokens"""
      
"name""Material"
      
"paramset"[
        {
          
"type""color"
          
"value"[
            0.6399999856948853

            
0.6399999856948853
            
0.6399999856948853
          ]

          
"name""Kd"
        
}
        
{
          
"type""float"
          
"value"0.0
          
"name""sigma"
        
}
        
{
          
"type""string"
          
"value""matte"
          
"name""type"
        
}
      ]
    }
  ]

  
"version""1.2.rc1"
  
"metadata"{
    
"estimated_size"884
    
"exterior"""
    
"interior"""
  
}
  
"name""Material"
  
"category_id": -1


So what do we need to do to make this work in the extra settings?  Like so(paste this into the Material Extra Settings):

eval {
 
var lbm2 {
   
"_comment""LBM2 material data saved by LuxBlend25 and altered for Luxus"
   
"objects"[
  {
    
"type""MakeNamedMaterial"
    
"extra_tokens"""
    
"name""Material"
    
"paramset"[
   {
     
"type""color"
     
"value"[
    0.6399999856948853

    
0.6399999856948853
    
0.6399999856948853
     ]

     
"name""Kd"
   
}
   
{
     
"type""float"
     
"value"0.0
     
"name""sigma"
   
}
   
{
     
"type""string"
     
"value""matte"
     
"name""type"
   
}
    ]
  }
   ]

   
"version""1.2.rc1"
   
"metadata"{
  
"estimated_size"884
  
"exterior"""
  
"interior"""
   
}
   
"name""Material"
   
"category_id": -1
 }
 Lux
.writeValue(lbm2);
}
NamedMaterial 
"Material" 


And this is a cool thing especially if you use a material from the LuxRender Material Database.  Yet this is javascript we are talking here, so perhaps there is more power here.  Perhaps we can hook up the DAZ Studio diffuse color channel to our matte materials color?  Yes we can, like so:

eval {
 
var lbm2 {
   
"_comment""LBM2 material data saved by LuxBlend25 and altered for Luxus"
   
"objects"[
  {
    
"type""MakeNamedMaterial"
    
"extra_tokens"""
    
"name""Material"
    
"paramset"[
   {
     
"type""color"
     
"value"Lux.getValue("Diffuse Color"),
     
"name""Kd"
   
}
   
{
     
"type""float"
     
"value"0.0
     
"name""sigma"
   
}
   
{
     
"type""string"
     
"value""matte"
     
"name""type"
   
}
    ]
  }
   ]

   
"version""1.2.rc1"
   
"metadata"{
  
"estimated_size"884
  
"exterior"""
  
"interior"""
   
}
   
"name""Material"
   
"category_id": -1
 }
 Lux
.writeValue(lbm2);
}
NamedMaterial 
"Material" 

The object will now be the DAZStudio Diffuse Color that you set on the object.  Any questions?

The diffuse channel is usually mapped.  How would one handle that case?

This looks like a pretty simple wrapper function, is there any way to build this in so it can be automated, ie.. click a button and point to a text file with the exported shader as is? Or, is there too many variables in the way this would need to be handled that would prevent that?

Just because I may have a strong opinion doesn’t make it any more (or less) correct than any other, just that I feel passionately a particular way at that moment.

For just setting it up to use the lbm2, yes this would be very simple.  We can wait for the next build, but it would be just as easy to make a daz script that does this.

Are there a set of Extra Settings that will set the Color Space, White Point, and Film Response so that I don’t have to do it manually every time?

Those would be in the ExtraSettings in the Render Settings, and it would work, but I will add those to the Render Settings in the next build.

I thought as much, but I can’t guess at the proper commands.  I trie things like ColorSpace “Adobe RGB 98”, but it caused error in LuxRender.  Maybe I should have put an equal sign, like ColorSpace = “Adobe RGB 98”?

Lux does not take named colourspaces.  You must specify the individual channels.

Lux’s default colorspace (SMPTE) corresponds to:

"float colorspace_red" [.63 .34]
"float colorspace_green" [0.31 0.595]
"float colorspace_blue" [0.155 0.07]
"float colorspace_white" [0.314275 0.329411] 

When you select a colour space or whitepoint preset in the GUI, Lux is using a lookup table to fill in these values.  You can see the values Lux uses in the file http://src.luxrender.net/lux/file/26b984c0ff01/qtgui/colorspacewidget.cpp at the top.

The film response is specified with “string cameraresponse” [“crfname”].
