I'm using PoserPro2010.

I started out with the Kids 4 Basic white Tshirt, and I created a Star Wars texture that I wanted to apply to the Tshirt.  I made the texture in Gimp. There was no node with the original white Tshirt, so I then created an image node in the Materials room and loaded the texture into the node, then I connected the node to the diffuse color. 

It looked ok in preview mode but when I did an area render the shirt wasn't black, but more a very dark gray, and you can see a bit of the kid's arm/skin through the shirt.  (as seen on the right sleeve)

I used a Jpeg, and it was originally two layers, one was 1000x1000 just filled with black color, then I positioned and overlayed the StarWars logo as a new layer and saved the file.  I'm not great at this but I did pick up along the way that I should either flatten the jpeg, or use a bmp, or tga when I save.  I tried the bmp format but unfortunately it didn't work and I got the same results when I rendered. 

I'm guessing I'm either doing something wrong connecting the node to the right place in the materials room, or with creating and saving the texture. I was hoping to use that same basic image node setup for the Kids 4 Skateboarder Shorts as well so I could cut down on all those nodes that come with it.

Hopefully this is an easy fix for someone experienced out there.  Thanks, any help would be  appreciated.

Try this, uncheck reflection_Lite_Multi on the PoserSurface; it is unnecessary. 

Reduce your highlight setting to 0.1 or lower.  Currently, it is set to 1000%. 

Reduce your Diffuse_Value to 0.8.  The number can be lower but that is a starting point.  Nothing actually reflects 100% diffuse light, it just increases your render time and wastes valuable memory resources.  I think the texture could be little smaller to fit the child's T-Shirt.  

That should fix your problem. 

The highlight size and intensity are not relevant, since the Specular_Color is black. It is turned off.

The Reflection_Lite_Mult is not relevant either, since nothing is plugged into Reflection_Color.

This is simple. You need to look more closely at the rectangle containing the ship. It's not black.

Everywhere else the texture is black, but not in the area around the ship.

And in your render, the shirt is black except around the ship.

You need a better monitor. I can see the gray clearly right in the texture.

I really need to calibrate my work monitor much more accurately, but I see what you are pointing out, BB.

I'm aware that the black square around the ship isn't completely black, closeup it's actually small stars. That said, it is however layed over the solid black of the first layer.

What I'm most concerned about is the small square rendered area I've selected on the right arm/sleeve showing the kid's arm through the material. As marked in the above pic.(Sorry, I should have mentioned that the area I rendered was just a very small square to save time)

The render area is not part of the square containing the ship, the outside edges of the ship's square are marked in the next pic.
 
HTH!

Well I can't tell much from that little square. Is there some reason you did not show us the whole thing rendered?

I'm not certain the artifact is from poke through. A full render would tell me more.

One thing I'm wondering about is the Highlight_Size = 100. That's a totally absurd number. Highlight_Size is usually from .001 to 1. Since the Specular_Color is black, it should not matter. But if that is causing some sort of numerical overflow, then you may be getting that artifact because of it. I don't really know - I've never put a number in like that.

Is there more than one material zone on that T-Shirt?  I'm just wondering if you didn't apply similar textures to the sleeves.

BB, I'm fairly new at poser (3 months) so apologies if I'm not quite up on the terminology just yet, this texturing stuff is all relatively new territory for me.  :-) My PC is rather slow, so I only rendered a small area to save time, I can certainly do a full render of the whole TShirt later tonight and post it in the morning if that will help.

Going a stretch here with my knowledge, judging from the preview screen I don't think it's pokethrough, especially since the figure is in the zero position and not posed where it would alter or wrinkle the material, if that makes sense. 

As for the Highlight_Size=100, I never really changed anything, I just loaded a default 2D image node, then loaded the texture and connected the node, didn't change any numbers anywhere.

Hborre, you might be onto something there, I will check that, however I think there is only one zone, it just says "TShirt" as far as I know.   I have to go offline at the moment, but I'll check in awhile and let you know for sure. There are two Kids Tshirts I've been using, one is the Skateboarder T-shirt, the other is the Kids 4 Basic Tshirt.  Pretty sure the skateboarder Tshirt is the one shown and only one zone, the other K4 Basic T has more zones, but they're just the trim of the collar and sleeves I think, will let you know for sure in awhile, thanks again.

 Did you ever look at the template for the shirt? I guess you did since the ship is placed corrrectly - but I can't figure out what you're showing here. Is that little grey square a partial render or does it come out like this when you render the whole thing?

BB- some programs set a specular and diffuse at 100. I think Max did it once. So that may be why, if the model loads like that. I agree that it's absurd.

What i'm wondering is the grey ambient. I know that the ambient value is at 0 and thus it should not matter, but... Poser is sometimes weird..

This might help solve this.....Here is the original node setup (above) of the ***Skateboarder TShirt *** which is the one in question.  hborre to answer your question it looks like there is only one Mat zone, but there were originally several types of nodes. I deleted all of those original nodes and inserted one new default 2D image node and loaded the texture file, then connected it to the diffuse channel.  I deleted all those other nodes to save cpu, as my pc is rather slow, and many of the image maps used in the original Tshirt were 2500x2500, my one texture is 1000x1000. (hborre, you might remember me mentioning that early in my other thread.)

I'm guessing maybe I shouldn't have deleted all the original nodes, as I don't know what they all are there for, but I do need to cut down on all those huge texture maps if I'm going to be using 15 kids in my animation, otherwise my pc would probably choke just loading them all.  :-) When I made a simple black 1000x1000 square swatch with a logo and it looked ok in preview, I thought I was all set, that is until I tried a test render.

I have also textured this one using the same procedure, and this one also looks ok in preview, however I haven't yet tried an area render on this type of shirt yet, but I will. Maybe doing a render on this other shirt will tell me if the problem is the shirt or my texture map.

Here is a render of the full Skateboarder TShirt with the Star Wars texture map I made in gimp.

Looks like the K4 Basic TShirt render seems to have come out better than the Skateboarder TShirt, although I still don't really know why! :-)

Any thoughts?

If you didn't change any values on the PoserSurface for the Skater's T-shirt, then you have an active specular channel which is causing the clothing to "shine".  Match the values of the Skater T-shirt to the basic T and they will appear similar.

You're right, I can see that the values are different for each on the specular channel. There was a math function plugged into the specular color on the original node setup for the SB Tshirt, and I deleted all those nodes without re-setting their values back to default.  I'll run down the list tomorrow and reset it all back to default by copying the other poser surface settings. Sounds like it should work, thanks hborre.
