It's SVDL's TextureFilter python script.  I don't remember if I found it here or over at RDNA.

There is a script floating around that will set all of the ImageMaps for you.  I'm not at my Poser system so I can't tell you who wrote it.  I'll try to remember to check when I get home.

Well, I was going to ask for thin glass in Poser 8 with Gamma Correction and IDL.

Are you going share any of this enlightenment with those of us lurkers who are living vicariously through you?

I've had this happen twice now - left poser up and running since Saturday (doing the occasional render in between other stuff around the house) and when I fired up Firefox this evening it couldn't resolve anything.  Shutdown Poser and all was good.

If I can find a pattern, I'll report it to SM.

Well I'm glad you posted it.  While I'm sure I received an email about it, I don't always see those in a timely manner.  But I read the posts here religiously.  And yes, I bought a couple of his models I've had my eye on.

Edited to add a thank you to hborre for the link to the tutorial.

Fantastic - many thanks.

IIRC if there is an image node for the bump map, but there is no bump map specified in the original shader, VSS would add a noise node instead of the image node, correct?  Is there a way to override that in case I don't want any bump?

I'm probably going to use Matmatic to build my templates, so the process would be: write the Matmatic code for my template using the appropriate node names, generate the material file,
create the new template, then load the material file into the template.  Seems way to easy.

Bagginsbill, a couple of followup questions:

1)  How do I setup a new template material so that it will use the existing image maps in my new shader tree?  (I have read the PDF on the VSS Home Page but it wasn't clear to me).  Here is the situation:  I'm working with a non-human figure (a building) and I need to replace the supplied shader tree(s) with correct shader tree(s) (for gamma correction, conservation of energy, etc - all the fun things you teach us about here).  I'm missing how to set up the image map(s) in my shader so it will take the specific ones from the existing shader.

1. Will VSS also copy constants from the poser surface node in the template to the target or does it only deal with nodes plugged into the poser surface node?  In the building I'm working with, the ambient value on all of the shaders is set to 1 (with a color of black so it's still a no-op).  I would prefer that the ambient value is 0 and the color is set to white.  If I set that up in the template shader will it copy that to the targets?

Thanks in advance.

IsaoShi - Would you please post a picture of the materials for your tile wall?  Thanks.

I'm not going to post any more results from the HSV Exponential unless anyone really wants to see them.

I've just had my D'Oh moment - Exponential tone mapping should really be called RGB Exponential because it's mapping in the RGB color space.  HSV Exponential is mapping in the HSV Color space.  If I had used HSV tuples instead of RGB tuples in my second listing, it would have followed the exact same pattern as the first data set.  (I don't know if I can make IrfanView show HSV instead of RGB, but I'm not going to worry about it now).

Whichway - Not really.  They are similar for the "Pure colors" (White, greys, and anytime an RGB channel value is 255), but not for other colors.  Take a look at BB's color and my Random Color.  This is why I included the extra results at 2.1 and 2.2.

It appears that HSV Exponential is a function of all three color values (which makes since from the name - duh....) and it is stable across the values.  What I mean is - the two colors in the top row of my render are BB's color (255, 128, 64) {the orange} and the same values, just in a different order (64, 128, 255) {the blue}.  With Exponential tone mapping the channel values were consistent and independent of each other - for a given tone mapping level a channel value of 128 will always map to the same value no matter what the other color channels values are.  With HSV Exponential, that is not true.  Compare the values returned for Dark Grey with the Green Channel values from BB's color.  And while I didn't list the blue version of BB's color in the above table, it's values tracked exactly with the orange version, just with the Red and Blue channel values swapped.

Give me a few minutes and I'll get some samples from some of the other squares.  (I was only using the right hand column from my original post for these results as well).

Here are the values for the HSV series as well - I've included a couple more data points.

Ok - I have tried to do as BB suggested and have run a quick test with Exponential Tone Mapping.

I started with the attached render (render settings in the next post) and saved it as a TIFF.  I checked all of the colors in the right hand column and they matched the input colors.

I then re-rendered with Exponential Tone Mapping on and saved as a TIFF.  I've checked some of the colors and here's a sample of the data:

(If there is a better way to present this information, please let me know)

So now the question is, What does this tell us?

If this looks useful I can also run it for HSV Exponential Tone Mapping.

[Edited trying to get the formatting better, but it obviously didn't work]

No - you need to turn on GI in the main Render Settings dialog.
