 lol I meant I am doing a render at this moment with the light meter


bagginsbill ( ) posted Tue, 11 May 2010 at 9:38 PM

Quote -  here it is with Ao,(on the ibl) she looks different, you see.
I am rendering with the light meter now, if that's still useful

It would be useful if we could see it.

And your earlier images also had AO.

You know there are two kinds of AO - light-based and material based.

You just said "here it is with AO". That's incorrect. Here it is with MORE AO.

You had it on somewhere before as well. Now you have more of it.

 ah ok more Ao lol sorry I am only learning as you can see from my join date.

Here is the render, this isn't good is it? too much red to the extreme.

Right - just for grins, turn off the IBL. How much light is there then. How does your skin look then?

Notice how the outer ring, which measures specular, is almost black. In Poser, IBL is not used for specular (too bad). By having the 100% IBL and relatively weak main lights, your specular effect is completely unbalanced. The two parts should be roughly equally reacting to light.

Quote -  Ok I can't sleep lol Ok here's my data! If only I could take screen captures.
My blinn node is plugged into the alternative_specular node, and haseccentricity at 1.00 and sec roll off at 0.0006 and the reflectivity at 0.0007. I have no Gc at all and the lighting rig is simple-1 ibl light at 100% intensity, 1 grey main light at 50% intensity and one spot light at 57% intensity.

Don't use gray lights. Use white and adjust the intensity with the intensity dial.

The effective luminance of lighting is the product (multiplication) of the color and the intensity. Gray is a number less than 1. Talking about lights with an unspecified gray is pretty much the same as telling me nothing about your light. Plus, if you ever start using render GC, such light sets will be completely different, because the gray will be anti-gamma corrected, resulting in a different luminance. Get used to white lights, unless you're trying to make a colored light, like blue or red.

Your Blinn parameters are out of whack. But you wouldn't know it, because you have so little specular light and so much diffuse light. (Note: This is a Poser concept and has nothing to do with physics. There is only one kind of light in real life. The material decides to treat it as specular or diffuse.)

As a starting point, your Blinn values should be .4, .4, .4.  It's easy to remember that way. It's not perfect, but way better to start with than what you have.

Once you get things balanced, then we tweak.

 ok here you go..hahahahaha.so dark


bagginsbill ( ) posted Tue, 11 May 2010 at 10:21 PM

Great. Now we're getting somewhere.

Set your non-IBL lights to white. You said you have one gray main light and one spot light. By main, did you mean infinite? The light types are infinite, point, spot, and IBL. There is no "main".

Drop the spot light for now. Set your main (infinite) to 75%, white.

Set your white IBL to 15%. Set the IBL Contrast (in the material room for the light) to 1.

Your figure will still be dark, but that's a valid light setup. We will then GC your figure and all will be well.

When I'm adjusting lighting, I don't do big renders or high render settings. You can get faster turnaround by doing a half-size render. On the render panel, there is a pulldown that usually says "Full". Change that to half for test renders.

Light Meter!


bagginsbill ( ) posted Tue, 11 May 2010 at 10:51 PM

Right. So the figure looks really dark because you tuned it to work in a blast furnace.

What is the Diffuse_Value? Probably a pretty low number. Usually it should be .8.

Or is the shader more complicated, such that a simple number is not meaningful?

file_452731.jpg

Wait. I just did a check. This is why the light meter is so useful. You're not telling the truth about doing what I said. Which "what I said" did you do?

This is what the meter looks like with a 75% white infinite and a 15% white IBL.

The figure is stock base V4. No fancy shaders.

 I did exactly what you did lol Why is mine so dark? How do i do screen capture?


bagginsbill ( ) posted Tue, 11 May 2010 at 10:58 PM

OK go fix your lights.

75% white
15% white IBL contrast = 1

ok I don't know lol

What is it I'm doing wrong I wonder?


bagginsbill ( ) posted Tue, 11 May 2010 at 11:11 PM

I don't know. Look at your light colors. On the Parameters tab, the Red, Green, and Blue should be 1.000.

I have to get to bed - have a meeting early in the morning. I'll catch up with you tomorrow.

 ignore the seams, i didn't add the shader to them.  I love the ambient of the skin now. You can see the blood underneath.


hborre ( ) posted Wed, 12 May 2010 at 1:51 PM

Your bump appears too high.  You should decrease it.  Also, did you set up your lighting as BB recommended?


MysticDaniel ( ) posted Wed, 12 May 2010 at 2:04 PM

 yes, did you not see the previous posts? lol 
All I get is darkness


hborre ( ) posted Wed, 12 May 2010 at 2:26 PM

Can you give us a screencap of your skin shader arrangement, extreme left side of the VSSProp, the number and type of lights you are using and their intensities. 


bagginsbill ( ) posted Wed, 12 May 2010 at 5:16 PM

I don't think it's VSS. There is no specular.

MysticDaniel ( ) posted Wed, 12 May 2010 at 10:00 PM

 you are right, there is no specular. I actually quite like the shader as is, even though there is no specular. I think I will keep this shader as seperate one, but advance with your ideas BB.
Sorry I have been busy all day, didn't have time to do any more work on the shader. So i will show you more tomorrow, ok?

 Sorry to reiterate and it's not really important since I'm using P8 now.. but I never heard about anything that broke hair in Poser 7, so I'm curious.. what exactly was broken with SR3?

MD - got your face here. It looks fine with VSS and the lighting I suggested. It will look even better with good lighting, instead of this ultra-simple basic test lighting.

I like the detail in the face, but the face is a bit pink, and the scalp is a bit gray.

I tweaked a few VSS shader parameters and got this. But now the scalp is green.

 wow she looks great BB, but the lighting is a bit dull still, i think, could you show me something in a daylight scene.

Thanks, how did you get this result? I couldn't for the life of me lol

I don't mind the scalp being green, because I will be applying hair to her.


MysticDaniel ( ) posted Fri, 14 May 2010 at 9:09 AM

file_452893.jpg

 This is specular added. Can you tell, this is also a different light by Corvas.


hborre ( ) posted Fri, 14 May 2010 at 9:23 AM

BB's light setting for these renders pretty much simulate daylight conditions.  The only difference is the lack of color tinting to the lights themselves.  However, not all scene daylight conditions are the same and is dependent on your background images.  In those instances, using P8 or PP 2010, you would elect using IDL within a skydome and forego using IBL.

Thanks hborre Heres more, what do you think?  


hborre ( ) posted Fri, 14 May 2010 at 11:05 AM

It's improving.  I noticed some artifacting on the upper left edge of her lip.  Actually, I see it at both ends.  What lights are your running now with this render?


MysticDaniel ( ) posted Fri, 14 May 2010 at 11:18 AM

file_452898.jpg

 lol the ears are the same, I haven't applied the shader to the lips and ears yet. I am using Valeria'a lights at Daz3ds store

New little experiment, added more imperfection, think I got abit carried away but I will tone it down, but I like the effect. This is my own light.


MysticDaniel ( ) posted Fri, 14 May 2010 at 2:53 PM

 with hair and I added more shader details too, I think I am pretty much done here as I am happy with the result, but comments are more than welcome.

I am an idiot. Of course.

Yah, so VSS works great with the Sarsa textures that come with the Freak, as far as I can tell.
