Weird artifacts in Room Creator Exteriors

I'm trying to use Room Creator Exteriors to create a building for a scene. Walls are fine, but when I add a wiondow or a door, while the view looks fine, ther are ugly artifacts in the render that make it worthless! I have uninstalled and re-installed all Room Creator 2 class products, but whatever it is, it is still there. Has anyone seen this? Can anyone identify the source of the artifacts?

That looks like overlapping geometry - are you sure there are not two parts there?
According to the instructions, you just turn wall sections off, not delete them. The underlying wall doesn't look like that in any case. I've been looking for a source for the texturing and can't find it.
renders are as ugly as sin. I use Rality, and when I use the brick texture it looks NOTHING like brick!
The room is a figure. You can't delete parts of it -- you can only make them invisible. I can't believe no one has seen this before...
Not sure about reality or the brick textures. I don't see what you are seeing in Studio when rendering with 3delight. Could you provide some more detail on what items you loaded, what wall sections you turned off, and anything else you did to the set? As Richard said, that looks like overlapping geometry, and the location is correct if one of the the three wall sections for that window size weren't turned off, but I'm not sure why you wouldn't see a similar effect on the whole wall rather than just towards the middle. Also I tried a render with one wall section still on, and I didn't get the same effect, but this is a render with 3delight in Studio so I'm not sure how it would hande that anyway.
*Added a sample of what I'm seeing witht he brick settings applied in 3delight. Not familiar enough with reality to offer advice, I don't know what the procedure is typically for how you go about converting studio settings, I just know that this product release pre-dates the reality release.
I think I know what's happening, but I don't know if I have a fix for it.
In RC2, the various materials are all present in each piece, but are made visible/invisible depending on which material you want to use. What you're seeing is all the materials together, with the invisible ones all overlapping and causing the artifacts.
Now, as was pointed out, Room Creator was released long before Reality or Iray, so I wasn't aware of this issue until someone mentioned it in the forums about a year ago. I did come up with a fix within DS, but I've never used Reality so I don't know if it works or how you would go about it. Anyway, here it is.
1. Load the figure you're using (or select it in the scene) and convert the surfaces to Iray.
2. Go to Menu> Tools> Geometry Editor (ALT+SHIFT+G), then open the Tool Settings pane.
3. You'll see 2 expanded lists - Face Groups and Surfaces. The Surfaces list is in alphabetical order, so the first 7 entries are for the outer wall. So, suppose you want to use '2exterior_stone', click on the eye icon for the other 6 surfaces to make them invisible. In other words, leave the surface you're using visible, and switch off all the others.
This only happens with PBR renderers like Iray and Reality, not 3Delight, which is why AlmightyQUEST isn't seeing the same issue. I'm sorry you're having this problem, but it's something I couldn't have known about when I built the set, and fixing it would require a complete rethink of how the set works.
If this is a dealbreaker and you're still within the 30 day period, DAZ will give you a refund, no questions asked. If not, you could still contact them and explain the issue. Hopefully they would issue a refund anyway.
You could also use a Push Modifier to move the problem sections away from the dsired mesh - we had a discussion of this in relation to Predatron's Step Van a few days ago (which I should have recalled). That would save having to hide bits of mesh, which I suspect may sometimes be a problem when you have multiple walls of the same basic type loaded but want to use different settings on them.
No problem. Only one customer has ever posted about this; it was some time last year. Once I figured out what was going on, I kept a copy of the info in case it cropped up again. So that came in handy.
My test renders were in 3Delight. I just tried Reality to see if it was as bad -- or worse. I will try the suggestion and see if it helps. Thanks for your response!
Uhhhh.... Convert the surfaces to iray? I'm gonna need to know how to do that. I have never done that.
Okay, well it works WITHOUT conversion. THANKS! But if you can point me at a tutorial for iray conversion, I will certainly test it!
Convert the surfaces to Iray
This isn't strictly necessary. DAZ Studio has auto-conversion, so if you load anything with 3Delight surfaces and are using the Iray renderer, the conversion is done for you.
You would need to convert surfaces if you wanted to tweak the materials. And that's done by selecting the object and all surfaces, then applying the Iray Uber Base shader (which comes with DS). By holding down CTRL when applying it, you have the option to Ignore textures - ie not replace them - so that you don't have to go back and set them all up again.
I don't have a link, but I'm sure there are plenty of threads about Iray conversion in the forums. Anyway, the main thing is that you've got it working. That's a start!
