"P8 comes with some fantastic plugins enabled by this API, and you will see more over time. These add so much to Poser's capabilities."

Wow. I am going to have to actually open some of those Python Scripts. The names do not really reveal what one will find inside. I have been using IrfanView's Color Correction feature to do what  Postwork Manager will do.

Does the GC in Postwork Manager work the same as in Poser Pro? That is, does it un-GC textures before applying GC to the final Render? Is there a way to simulate the Poser Pro ability to turn off GC for specific textures?

I finally found the setting for light fall-off, and again, Wow. This is so much more realistic for lights. Now I have to figure out how to redo my lighting to take advantage of this.

bagginsbill - Obviously, I love the technical details. I blather on endlessly on these threads trying to figure out what's "really going on". At least you get the answers right, though I not sure asking Stewer isn't cheating. Please keep it up.

Whichway

fwiw, I really enjoy your posts BB.  I might not render in Poser any more but no knowledge is ever wasted and you never know when it'll come in handy.
but yeah - if they don't like it, they can FOAD

I thought you'd get an answer to these questions by now...

No, it doesn't. It only GC's the output render.
If you want to anti-GC incoming textures/colours you have to do it in the shaders, the same way as we did in Poser 7.

I am patient I can wait to get a good answer. Thank you.

can someone who undertands anti-TM post a screenhot from the material room? how to anti ETM.

thanks.

I like the examples posted by Bagginsbill with different settings and want to try some of these on my own scenes but I cannot find a "gain" adjustment, just the "exposure". Could some kind person point me in the right direction please?

As I said, the gain has no GUI widget for it, so I was setting it via Python. Stefan and I briefly discussed it. His opinion was that Gain is not useful. At the time, I was not able to agree or disagree, so I let it go. Now that I've examined the formula closely and rendered with it, I disagree with him. The Gain is useful. It is not useful if you are doing true [0, infinity] into [0, 1] mapping, but that's not what we're doing. We're mapping, for example, [0, 1] into [0, 1] and for that the Gain is very helpful. Notice the case where I had Gain = 1.11, that is exactly what I did. The range [0, 1] mapped to [0, 1].

Nobody has done it. I only mentioned it as an academic point. Do you really want a photo converted to [0, infinity] color space?

i want to render reflection but i dont want to change the pic :)

If I can resurrect this thread for a moment, on the Dimension 3D panel, there is an unlabeled slider next to the Tone Mapping Enable checkbox. Is this perchance the Gain?

Whichway

I find your posts very useful Baggins.
Often times you talk way over my head but that's okay, pictures speak a thousand words. I also appreciate your posting the settings too.

BB, does it matter what filter number you choose...1,2, or 3?
If so can you please explain the difference between them in laymans terms?

yes, whichway - the unlabelled slider (sr0) on d3d's script is for variable toneGain.

Thanks you!

Whichway

did someone manage to make an anti tone mapping shader? 

Quote - Now rendered tih:

exposure = 2.3
gain = 1.1

Could anyone give say (for dummies) what the python script to make the gain 1.1 would be, where you enter it, and I guess you have to do it on each scene or can you set it to stay that way always?

I think, but have not personally verified, that the unlabeled slider next to the Enable Tone Mapping checkbox on the Dimension 3D panel is the gain.

Whichway

said variable is also mentioned in python manual, it is probably in one or more lines of d3d's script (in case anybody wishes to read the script) and the variable, once assigned, is available by saving and reading the pz3 file.  in OS X, use BBEdit.  yeah, I just checked - it's in two lines in the script, along with a line "it's currently not possible to turn GI on/off by Poser Python".  which was the only way we could do it in poser 7.

Thank You, I don't know why I missed the notification of the thread, but I hunted it down got the info and am a happy camper. Again Thank You.

i did now some tests with reflection. i thought that we have to anti-TM the material for reflection. but it looks like we dont have to.

correct bagginsbill?

Correct, you don't have to do anything elsewhere - just on the photo.

i did a test render with IDL.

this is the shader.  but i dont understand why is there a bright edge at the bottom. the reflection from the ground shout block the env_sphere.

Uhoh. Do you think the light leak through single-layer polygon bug is back?

That was fixed, but maybe it has returned.

Try using a thin box under the sphere - do you get different results?

with the IDL render it looks to me that the rays only see how the ground is lighten up and after that they add the shadows.

Interesting.

very interesting. its to bad i can not use now reflection. but i am not so mad since i got shadow samples. it rocks. so good. and IDL is working very good and very fast . i get good results.

i will wait until SR2. maybe december? ;) :) 

 Perhaps reflections without IDL as a seperate pass, then assemble in an image editor - for now

take care

can not do reflection in a seperate pass because then IDL wont be in the reflections.
