How to turn reflections off in old Poser shaders in iRay engine

I'm using a really ancient, freebee set that was made for Poser, and when I try to use it in iRay, it makes the walls reflective enough that you can see the floor in them, and the floor reflective enough you can see the walls in it.  I want to turn this reflective effect completely off, because among other things, I'm pretty sure its making my render take 20 minutes when it should probably take no more than 5, since literally the only thing I have in my scene is two people and what amounts to a piece of furniture.  And the walls and floor.

I even tried applying !Iray Uber Base to the walls and floor to convert them to Iray shaders, but it made no visible difference in the render.  And it still took 20 minutes.

    Applying Iray uber base shader without changing any setting is exactly the same as what automatic conversion does, so it's no wonder the result is the same.

    Can you show us what the surface settings are?

    Well, I've reverted back to the Poser surfaces version, and will give you screengrabs of that.

    Turn Specular Strength down to 0 and see if that helps.

    What I usually do is select all surfaces, remove any reflection maps, and turn down the Specular settings mentioned above. Then apply the Iray Uber Shader. If I don't do it in that order, then I'm never entirely sure if the Poser reflection effects are completely removed from the surface parameters so I can replace them with Iray shiny effects where I want them.

    Poser material settings have always been garbage in DS, most of the time character sets looked like they had been dipped in varnish in 3Delight, nice to see the crappy Spec settings doing the same thing with Iray cheeky.

    Specular Strength converts (poorly) to Glossy Layered Weight, and Glossy converts to Glossy Roughness, in between those two Iray settings is Glossy Reflectivity, by default that's at 0.5.

    Basically you want to mess about with those three settings as well as the Glossy Color to get the Specular effect you want.

    Okay, reducing Specular Strength from 100% to 0% removed the reflective effects from the walls and floor.  The render went from about 22 minutes to about 16 minutes.  I can live with 16 minutes.  :D
