I do not seem to get any answere in the "Poser technical" forum, so I'll try here.

Your question isn't totally clear, but from what I can see, the answer would appear to be "no." Poser 4/ProPack doesn't use material shader nodes like Poser 5 does. You can creat MAT files that apply texture, bump, reflection and trasnparency maps and assign strength values to each, but a MAT of the complexity shown in your screen shot wouldn't work in non-P5 versions.

Sorry, I can see that my question would seem unclear. What I'm really wondering is about using a texture-map to control the "reflection value" (like "transparency value"). Like this: white in the image-map would mean using your full "reflection value" and black would then be -1 (or -100% of initial value).

No need to apologize, I only mentioned that because I wasn't sure if I was answering the right question. :-) Here's a screen shot of the P4/PP materials editor. As you can see it's much more simple than the P5 materials room. I think this might give an idea of how it works. Reflection is affected by the slider bar, whether or not you check "multiply through lights," the color used for "Reflective Color" at the top of the editor, etc. P4 doesn't allow for true reflection, you have to use maps. Some people use "blur" maps, others use photographs meant to indicate surrounding environment. The values shown in this image, for an item of clothing by BVH, are different from how I usually do it, but there are many ways. I'm sorry if I'm not addressing what you're really asking, but maybe this will help a little.

Thank you xoconstle, this really answered my question. My hope was to be able to use a "reflection image" on a surface which have "total" transparency on some of its parts. I can see that it won't work in PP, it would show reflections in the transparent area too.

Now this gave me another problem (I can see that in your screenshot). I've been using images to control the "specular value" too, which probably won't work in PP either... :-(

Nope. No spec map, no reflectivity map in P4. You could fake up the latter by creating more materials -- one set to reflect, another not.

Ok, thanks! ... I really think I'll stick to P5-mat only.

I've only had P5 for about three weeks, and I'm already very spoiled. :-)

I've only had P5 for about three weeks, and I'm already very spoiled. :-) YES! After all the horror stories I heard about P5 I was very, very wary of upgrading, but I finally took the plunge and I'm so glad I did. P5 is superior to P4 in a multitude of ways, and it's very stable on my system. bonni

I did upgrade to P5 as soon as it was released. I've cursed it many times (stability is not a word I would use when describing it), I'v put alot of money into it (expensive RAM). It's the only software I own that constantly make me think I need a faster, bigger and meaner computer (I also own Lightwave and DeepPaint). But, to be honest, I would never go back to P4.
