I'm working on some eye textures, but since I don't have a program that supports transparency maps, I don't have any way to figure out how they work. I wanted to put these eye textures in the Marketplace, but if I do they'll need trans maps for the Poser users. So my question is, on a s trans map, are clear areas white with opaque areas black? The reason I'm asking is because the corneas of the eyes need to be clear.

Transmaps: White will show in render Black does NOT show in render. ;=]

So you are making poser items to sell in the marketplace without owning poser at all?
Brave soul!

Why not download the free daz Studio, to at least test them to see if they work properly?

Garee: Hehe not quite, I do have Poser 3 and Daz Studio, but P3 doesn't do trans maps. DS must do them but I have yet to figure out where the commands are. ;) I totally forgot about DS though, it's so clumsy and cumbersome that I never use it. Thanks, I'll try that. Besides, what I'm making is eyeballs, they're not that Poser exclusive ;) I just want them to map correctly in as many apps as possible. Dr. Geep: So, a clear object should be black on a trans map? I don't know for sure because the only trans map I have on hand is from a free MilDragon texture. It's for the wings, so it's gray, and I wasn't sure which extreme was which ;)

Black areas on a transmap will be invisible if ... TranMax = 100% -and- TransMin = 100% and Highlight is set to 0 and BLACK cheers, dr geep ;=]

You have other settings that would apply. In P5, and I think P4, you can make a whole material transparent (a material is one way of defining part of an object, which can cross body-part boundaries, such as a long sock). That might be better for what you're doing. But without a more recent version of Poser... Not at all easy.

In that case, for many figures, the iris is a distinct material, and the only problem might be where it is on a texturemap. Some figures have it tucked away on the general head texturemap, and the UV mapping means you have to match that. DAZ3D usually have well-labelled templates available. The extra layers, and their transparency, wouldn't need changing from the default for a working figure. If you're doing exotics, you might have to do the whole eye. I've not seen an eye where the UV mapping for pupil/iris/white isn't a single area, and the different parts cannot cross material boundaries. You'd have to do that to get a slit pupil, or just different light levels. Which is a thought -- especially with slit pupils, you get some noticable changes as light level drop. A slit pupil changes shape. Would it be worth putting some index marks outside the texture area to make it easier to identify the eye's centre?
