Issue with Room Creator Exteriors Window Piece

Posts: 74
So am hoping someone can help me here, I been using Room Creator Exteriors and Room Creator 2.0 to build a large house, it was going well until I discovered this black on the outside wall and no idea what could be causing it
Trying to think of the information you need to be able to help me figure it out, sorta hope someone has had same issue at some point.
- it appears on every single window piece and I have increased the width of the window via xScale
- I have been through all the surface options for exterior and removed any black colour.
- I am using sun-sky only dome and Environment Intensity is 0.50
- The black on left of the window goes from the edge of the piece right to the window, so it's not the whole window piece, which is odd.
At first, I thought it was kitchen items on the other side of the wall that was causing it, as when I move the piece away from the overall building, it disappears, so maybe something to do with lightning? I hope not, as that be very tricky to resolve I think.

Is it possible that, when you scaled that window piece, you got overlapping wall pieces which would probably cause the artefacts you're seeing?
I checked and as you can see in the screenshot, the next piece doesn't overlap.
I do sometimes have them overlapping, also, this specific window isn't actually been increased in size.
So tried two things this morning, I readded the exact same wall from Room Creator Exteriors (15_05 Window Horizontal) and can see that in the first screenshot (white line texture) can see there black at top and bottom, but it's not as bad this time. It only happens with pieces from Room Creator Exterior and specifically, all windows I have added. Can sometimes see black on some plain wall pieces, like to the left of the window.
I tried adding the same size/style of window from Room Creator Version 2 and can see that in the second screenshot (stone texture), as you can see no black, so whatever the issue is, it is located to Room Creator Exteriors only.
So I don't have a fix but do have an option, I could just replace all the outer wall pieces with RCV2 instead, but would like to try and figure out an actual fix but am at a loss, and can't think of any more possible solutions.
Also, if I use RCV2 for the outer wall, will need to figure out how to remove the moulding at the top (the white piece that sticks out) and the baseboard (wood at the bottom), as looks little odd having that on the outside.
This is an issue that came up before, and there is a solution, but not one I can implement as a fix to the product because it's an issue with overlapping surfaces in Iray (Just like Sven said). But if you follow these steps, it should work.
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.
Let me know if this solves the issue. If not, I'll check again. Sorry about this. I know it's a hassle, but for the life of me, I can't find a way to fix it permanantly.
Yup, that resolved it, thank you very much
is a bit of a hassle but it's not that hard to resolve once you know about Geometry Editor tool, I really should spend more time learning about the different tools in that tool menu, learned a lot but still a lot to learn.
Think I might go with room creator version 2.0 windows and wall for outside though, like the stoned texture more but I now have both options available again, thank you, love the Room Creator stuff.
EDIT
Encase anyone goes to post a solution related to me mentioning figuring out how to remove the Moulding and Baseboard in a previous post of mine, I did figure that out. Reduce Opacity to 0, guessing Geometry Editor can remove it as well.
Ah, good. I'm glad you got it working. As I said, it's a pain, but once you know the steps, it's easy enough to do.
RC was released before Iray was even heard of, which is why it was never a problem.
Sadly, ran into more issues with this black on walls when using 11_11_Main Roof and 11_0 Scene 2, the Geometry Editor fix you gave me is not working on they two assets, its the roof front and roof back parts that not working.
Shall give 19_21 Dormer Section and 19_21 Roof Section tomorrow, see if I can get a decent roof with them, the small roof is just to small to use on mansion I built (it not really a mansion but feels like it after doing it lol)
Hopefully, you can figure something out with the main roof and scene 2.
Also, I noticed that twice I had to redo the fix on walls with Geometry Editor, seems the fix isn't permanent or maybe I did something that reset it but not sure.
UPDATE:
Think I see why the black on walls returns, after I applied the fixes to them, pretty certain its to do with "Use Symmetry" and checking that, deliberately checked that last night after applying the fix to two sides of the house, this morning they two sides of house needed to be redone as black on walls had returned.
Found what I think is a permanent fix and something that may help Maclean
When I apply the material "12_01 Stonework" the black disappears from the roof, it is the only one that results in no black, so maybe that can help figure out why the black appears on other surface types.
As you can see in screenshot and iray preview, there is no black at all using that material and I only hide stone_lower and stone_upper in geology editor, as looks better without.
Hopefully, this is finally it now
I just saw these latest posts now. I'm taking notes and I'll try your fix. Thanks for being so patient and persistent with this!
Just an update on the quoted post of mine, the black did return this morning for me but I didn't check the "Use Symmetry".
Still think its something related to symmetry though, as I did add "11_00 Scene 2 (roof)" to house and before that was playing around with "19_21 roof section", same asset so logically I assume there is symmetry between them.
Also, couldn't see a way to add triangle piece of wall that shows on preview image (before you click to add to the scene) for 19_21 roof section.
Actually, there isn't a triangular piece in that. It's an optical illusion in the angle of the thumbnail. If you look closely at the thumb, you'll see a tiny corner of light (just below the 'se' in the text). That's where the ceiling almost meets the roof. And because the thumb before it (19_21 dormer section) is at the same angle, but with no ceiling, it looks as though the roof section has one.
As far as I remember, the only way to do it would be to use the 11_12 small roof figure, and switch off the pieces you don't need. Or maybe extract the triangular piece from it with the Geometry tool?
ah ok, bit frustrating not having a triangle piece of wall, as you can't really use the roof/dormer pieces to make own roof, as there always be a triangle gap at one end.
Although small + main roof and the scene 2 roof will generally always do for a roof, now that I have a material I can use for the black wall, it would be nice to have a triangle piece of wall to go with the dormer section or roof section to make own roof though.
The reason the 19_21 roof section doesn't have a trianglar front piece is that it's an extension. I still think the best thing would be to extract the triangle with the Geometry Tool and save it as a new prop.
I wouldn't know how to do that with Geometry Tool. until you mentioned the tool to me, I never even looked at it.
I used "11_00 Scene 2 (roof)" with "12_01 Stonework" and that did the job for me.
PMd you.
