olyconstruction Posted December 8, 2015 Share Posted December 8, 2015 Hello guys and gals, I was wondering if someone could help me figure out what is happening during my ray traces. I hid a wall to get this view and once i started the ray trace, i noticed a weird pattern on my Washer/Dryer. Has anyone ran into this while ray tracing? I have tried changing the material but it keeps giving me the same effect in the same two areas. Link to comment Share on other sites More sharing options...
keithhe Posted December 8, 2015 Share Posted December 8, 2015 Just a guess, but camera might still be partially in wall? What distance do you have clipping and walls set in "default settings" > "camera" > "general camera"? Link to comment Share on other sites More sharing options...
olyconstruction Posted December 8, 2015 Author Share Posted December 8, 2015 I turned the wall into an invisible wall so it will not show regardless of where i move the camera. My Clip Surfaces Within is set at 36" and Remove Wall Within is set at 48" Link to comment Share on other sites More sharing options...
keithhe Posted December 8, 2015 Share Posted December 8, 2015 Can you post the plan? Much easier to see what might be going on. Link to comment Share on other sites More sharing options...

keithhe Posted December 10, 2015 Share Posted December 10, 2015 Oly, (don't know your name) I have spent quite some time on this, and I'm still at a loss. I thought, initially this might be lighting or material related and made a number of changes, with same results. I put the dryer outside, same results, so this is something in the plan, and not program related. I see this z-fighting, if that is what this is, in other locations/materials too. A variety of camera views shows this as well. I changed the sun angles and didn't help on floor overviews. This seems like what I see in a very dark room (little or no light) but not the case in floor overview where this is still happening. There are some really smart folks on this forum, and hopefully one will come along and figure this out. I'm as curious as anyone right now.

keithhe Posted December 10, 2015 Share Posted December 10, 2015 You are going to laugh (I did) when you hear what this was. It was the most extreme case of this I had seen. More to follow in a few minutes... I need to take a few shots to explain this Link to comment Share on other sites More sharing options...
Solution keithhe Posted December 10, 2015 Solution Share Posted December 10, 2015 OK, I write this to hopefully help others, who might experience same issue, and not as a knock in anyway to you. I did this early on in my CA learning curve to a much lesser extent. As it looked like z-fighting to me, I have learned that this can be caused by generally just four things.. 1) Two objects in same space. (checked this and not your case). 2) Too thin a material. (can't really be the case here, with objects that were fighting, but you will see this on roof tiles and siding sometimes. If you do, simply change the material thickness to like 1/4" or something and it will fix usually) 3) Too large a terrain perimeter (not bad in your case) 4) Too far from origin. Bingo, we have a winner. See below shots, but in the all on (lower floor) you have some type of site plan a few MILES east (to the right) from the actual house and terrain perimeter, but that was not the really issue. The real issue was that you were, holy cow...... 10.5 MILES, yes miles, from the origin. That's way out of the range of this program, even if the plan was to build a subdivision. (see photos attached) Lessons here. Start your plans at the origin. Tommy Blair taught me years ago to set a few walls in an "L" arrangement, about 6 feet long is fine, right at the origin (0,0). Now save as your template plan and you will always start right there, as walls are usually the first thing we do. Although it is not unusual for AutoCAD folks to have things all over the space, does not work here. The site plan way out to the east, need not be there. Should be a layer. If you are first floor, all on plan, click the zoom extents to see what might be hidden out there. If anything is outside your terrain perimeter, find and get rid of it. Oly (and please add your name to your signature, with version you are using) here' how to fix your issue. Once above is done, Click Edit > Edit Area > Edit Area All Floors. Draw a marquee around entire plan with perimeter. Next Click Transform Replicate Tool Click Move Make Sure Absolute Location Radio is selected Make X and Y (0, 0) This can be messy at times, so save a copy before you start. See photo attached. The tiny little black dot top left is the entire contents inside the perimeter. The "X" is the origin 10.5 miles away. The other blur to right of the plan perimeter is a site plan or something (can't be there) Link to comment Share on other sites More sharing options...
olyconstruction Posted December 10, 2015 Author Share Posted December 10, 2015 I appreciate the help Keithhe. I'm not sure how I ended up so far away form the origin but I will update that plan as well as my template. Thanks! Link to comment Share on other sites More sharing options...
