Here we go, basic car paint material:

    # Material 'carpaint/latex'<br></br>
MakeNamedMaterial "carpaint/latex"<br></br>
   "string type" ["carpaint"]<br></br>
   "color Kd" [0.124526 0.294963 0.203289]<br></br>
   "color Ks1" [0.754852 0.773852 0.500392]<br></br>
   "color Ks2" [0.442047 0.629024 0.290352]<br></br>
   "color Ks3" [0.227329 0.546751 0.374624]<br></br>
   "float R1" [1.000000]<br></br>
   "float R2" [1.000000]<br></br>
   "float R3" [1.000000]<br></br>
   "float M1" [1.000000]<br></br>
   "float M2" [1.000000]<br></br>
   "float M3" [1.000000]

For the most part, there is one diffuse channel, three specular channels, then the reflective channels. Also, there are a couple of presets for fairly standard car paint colors:
blue matte, blue, white, 2k acrylac, bmw339, opel titan, polaris silber and ford f8

Obviously, if you're looking for a particular look, go with the custom material example I posted above, you could define it with the presets this way:

    # Material 'carpaint preset'<br></br>
MakeNamedMaterial "carpaint preset"<br></br>
   "string type" ["carpaint"]<br></br>
   "string name" ["blue
matte"]

Hope that helps! ^_^ I'll also add it to the LuxPose materials wiki if needed.

Thank you! I've copied it down into my Word Document. Any idea on Leather?

Well, from the materials database, there are at least 2 types of leather materials, but I'm looking into converting them for 0.7 materials. Here's one that might work:

    # Material 'rough_leather'<br></br>

You may need to play with the bump map and color settings a bit, but I think that should work for detailed renders. Also, the glossy exponent is set a little high, not to mention it's on glossy_lossy for this material, so some additional adjustments will be needed.

I'm going to test that, but I'm not sure how to edit the file with what you have there. I exported a simple scene and I want to test the material on the Poser sphere. In a text editor, it looks like this:

#----->   BallUV3_1/Preview    <-----

MakeNamedMaterial "BallUV3_1/Preview" "string type" ["glossy"]
"color Kd" [0.576470414797 0.576470414797 0.576470414797]
"color Ks" [0.0 0.0 0.0]
"float uroughness" [0.258086156304]
"float vroughness" [0.258086156304]

So how do I put the above onto the ball? I'm sorry, it's not clear to me.

Try taking that whole piece of code and put it in the .lxm file just above your #----->   BallUV3_1/Preview    <-----

Then replace "rough_leather" in  MakeNamedMaterial " rough_leather``"
with "BallUV3_1/Preview"
and remove the old Ball material section,
MakeNamedMaterial "BallUV3_1/Preview" "string type" ["glossy"]
"color Kd" [0.576470414797 0.576470414797 0.576470414797]
"color Ks" [0.0 0.0 0.0]
"float uroughness" [0.258086156304]
"float vroughness" [0.258086156304]

That should make your ball use the new "rough_leather" material.

I get this line in the Lux log:

[2010-09-20 18:47:52 Error: 41] Couldn't find color texture named 'rough_leather::Kd'

Guessing that the 2nd line from the top is incorrect, Texture "``rough_leather ::Kd::amount" "float" "blender_clouds"

it might need to lose the ::amount, just guessing though.

I got Laurie's green gel to go through to Lux and I'm rendering that right now. My mind doesn't seem to grasp some of this. (but I am somewhat distracted right now. I've had a relative living with me until she buys a place. The place is bought so now getting ready to move her stuff out and to the new place.)

It's a pain if you miss an area as Lux will spit out errors about things being named improperly or the material names between section not matching.

Oh, and here's what the texture will look like on a pair of clothes (attached above). Sadly, it looks better in close up shots or high res renders, along with different lighting. You may also want to change the colors to something more appropriate as it appears a bit... purple? That's controlled where it says "color tex1" and "color tex2" for the most part.

Sorry for not responding sooner! I was aware from my computer while it was rendering the example image I attached.

I have copied your reply to a Word document for further study! Thanks for getting back to me!

I've been trying to keep up with all the discussion in this thread, and I'm confused on a point. Does the current exporter recognize and IBL light or not? I have a scene I just did and I thought it would make a nice test Lux scene, but it contains an IBL light.

Technically, IBL lights are recognized in Lux when they are setup properly, as mentioned here. I'd say with infinite light environment, but I can't be sure. Plus, you'd need to use the OpenEXR format for high dynamic range images or convert them images either in Blender or with another app; but, you can use jpeg or png image files for low dynamic range lighting along with additional light to balance out the missing information. Personally, I've never really used them in Lux as using a sun+sky light or a custom shape seems to work well for me.

As for the current LuxPose exporter, I'm going to take a guess and say... not at this time.

If anyone knows more, feel free to comment on the subject as I'm not too knowledgeable in that area

There is no need to convert the HDRI files to OpenEXR format, LuxRender supports .hdr format.

LightSource "infinitesample"<br></br>
    "string mapname"
["kitchen_probe.hdr"]<br></br>
    "float gain" [1.0]

The easiest way to copy the material into the lxm file is to copy the whole material and just change the name at the very end.  Where it says MakeNamedMaterial change it from:

MakeNamedMaterial "rough_leather"<br></br><br></br>
to:<br></br><br></br>
MakeNamedMaterial
"BallUV3_1/Preview"<br></br><br></br>
That way all the texture references will be correct.  That's
the method I've been using while using LuxBlend to work out
materials for scenes.

  I just leave the reference line ( # Material 'BallUV3_1/Preview' ) so I know what the name needs to be.

Just to reiterate, the info that says .hdr is not supported is outdated.  According to a page on their wiki (can't remember which, I've looked at too many :blink:), they added it in 0.7.

I kind of figured as much and deleted my lights and set up a single Point light for the export. I started my Lux render and it looked really good except I've got a problem with the eyes. Someone mentioned using Lux glass material on the cornea and eye surface. Can someone tell me how that would be done?

Ok, try this for black car paint (does not use the Luxrender carpaint shader):

MakeNamedMaterial "YourMaterialNameHere" "string type" ["glossy"]
"color Kd" [0.0 0.0 0.0]
"color Ks" [0.02 0.02 0.02]
"float uroughness" [-0.258086156304]
"float vroughness" [0.258086156304]
"float film" [0.1]
"float index" [2.3]

Will show how it looks in a few...

Laurie

Thanks, giving it a try!

Laurie

BTW, if something doesn't turn out looking right to you, try removing the minus sign in front of the uroughness. This is a work in progress...lol.

Laurie

So far it's looking good! I just wish that the noise in Lux would smooth out faster than it does.

For eyes, I use this:

MakeNamedMaterial "Fill_In_The_Blank"
"string type" ["glass"]
"color Kr" [1.000000 1.000000 1.000000]
"color Kt" [1.000000 1.000000 1.000000]
"float index" [1.500000]
"bool architectural" ["true"]

Architectural glass, so it won't make potentially weird refractions on the eye.  This is assuming you have an eyeball surface covering over the pupil/iris/eyewhite.
  

Cool, thanks! I'll have to try that next render. This one's already been going and hour and looks nearly done.

Laurie, your carpaint shader worked very, very nicely for latex! This is turning out to be a decent render.

bikini materials :

rings : luxrender metal gold
trim : LaurieA black carpaint
cloth : ayanamatrix Leather 

all others materials unmodified from the LuxPose export

3 point lights : top, front and back. set to 4000°K, a typo placed the front and back light in the same group so i cannot balance the two

stopped after 2 hours, i have to go out, render again when i come back with some minor modifications

Thanks to ADP, BB, Dizzi and odf for this plugin
Thanks to LaurieA, ayanamatrix  and all others in this thread who provide materials and ideas

MakeNamedMaterial "YourMateralNameHere" "string type" ["glossy"]
"color Kd" [0.0 0.0 0.0]
"color Ks" [0.02 0.02 0.02]
"color Ka" [0.0 0.0 0.0]
"float uroughness" [-0.005]
"float vroughness" [0.005]
"float d" [0.1]
"float index" [2.0]

That may work a little better than my other post for carpaint (and latex if you prefer...lol). There's a little more shine in the half-lit areas.

Laurie

The car is Bazze's Muscle Car and it looks lovely in that nice 70's color made famous by appliances and Dodge Dusters ;o).....

The chrome bits are just a glossy with a gray color slightly above 50% and a bright specular color....the rims are Luxrender's aluminium metal shader and the car paint is the shader I was experimenting with last night, slightly modified from the original. The window glass is actually an architectural glass/regular glass mix at [0.3] with the regular glass being in the lesser amount.  :o).

If anyone's interested in the shader code, I'll post em.

Laurie

Thanks so much for all your help, Laurie! And yes, we'd love to see the code!

Loving playing around with this and Luxrender! Thanks to all involved, can't wait for it to be finalized.

Here's a couple of test images

What material did you use on the glasses? The one that Laurie published? They look fantastic!

Wow, I love those glasses and the rose, absolutely beautiful.

You should try using the new velvet material on the rose petals, and have you tried mattetranslucent material on the rose leaves?

Figured out how to add to the Material Wiki. I added a few things that Laura gave me.

rjjack, I'm pretty impressed that shader worked out so well for you. :D Aside from possibly altering the color, did you happen to increase the bump depth as well, or did you leave that alone?

Quote - rjjack, I'm pretty impressed that shader worked out so well for you. :D Aside from possibly altering the color, did you happen to increase the bump depth as well, or did you leave that alone?

Nope, any new weekly after 8 September should have velvet in it; I'm using an 11-09 OS X weekly, it has velvet.

Well there is still a lot of good stuff happening that can be used in the other builds :) so I would not , not read along... specifically to the OSX version weekly build (9-11-2010)  though this is the note from the Lux forum :

Build_of_sept_11

new:

• requires OSX 10.6+ due openCL dependencies
• splash versioning @ 0.8(dev)
• correct versioning now
• fixed halltspp and halttime
• freeimage 3140
  -boost 1.4.3
• new hybrid-render ( dummy )
• refinements to glossy
• velvet material
• adapted exporter

Quote - i have Xp 32bit . which should i download? SSE1 or SSE2

If your computer is Pentium IV or newer or Athlon AMD64 or newer download the SSE2 version.

Quote - and what is Non-OpenCL CPU only builds?

If your video card is not ATI Radeon and/or doesn't support OpenCL you must download Non OpenCL and you won't have GPU acceleration, only CPU rendering.

You have to make sure the config files in the AIR directory are installed.
If you unpack all of the content from the zip in one directory anything should be in place.

No, not really. This instruction is written but commented out ('#' in front of) in this version. And the whole line is only written if you have set the flag in your config file.

This is my favorite color yet. And I posted the recipe for this one on the wiki.

Looks really good.  Since no one reads the general question topic, I'll have to ask here.

I have 2 questions:

1.  I was under the impression that distant lights were converted to sun.  If so, does it have to be a special name?  I tried, and it didn't convert; but i didn't try all combinations of sun names.

2.  With the editing of materials, I looked at the wiki and I am somewhat confused.  It says:

Please pay special attention to material names as you will need to replace "YourMaterialNameHere" with the name of your material. 

Does that mean there are only certain materials that can be used, or does it mean we can name it anything we want as long as it is unique?   I guess it would help me to see the syntax of a sample material, along with a working example.

Thanks!

Thanks for the reply, but I unzipped right into the poserscripts folder and  double checked that the config files are in the Luxposedata folder. I also have another version unzipped in a temp folder, neither work, hmmm.

I have the Luxpose interface installed from the AIR file in it's default location (different from the rest) does that matter?

    if pFilm.hybrid.strip()=="true":
AttributeError: 'NoneType' object has no attribute 'strip'

the error don't show if you add this line in the dataOut.bbml  in the Film part :

hybrid=true

do you have added some new parameters in the AIR interface ?
usually i edit dataOut.bbml on my text editor since i change only the filename
