2 20.1.1.1 Update Notes

2.2 Ray Tracing • Fixed a problem that could cause black squares to appear in ray trace images in some cases.

 

Seems like that was fixed.  Are you using update 2 20.1.1.1 ?  If so it likely needs to be sent in to tech support again.

This issue is caused by very large models.

Try making your terrain smaller or hiding it as a test.

 

My guess is that it has something to do with the ray tracer trying to make a calculation based on the origin and the distance becomes too great at some point.

Yes, it is a very large terrain perimeter, multibuilding lot.  I will try out changing terrain.

thanks as always to all

I'd be happy to throw in Thea for you real quick for fun, wouldn't take any time at all if you export as 3ds and the results will come back looking very sharp

Wow, that would be much appreciated.

Attached is zipped file of 2 3DS files, one with terrain, one without.

 

This is SUPPOSED to be a 10 acre lot with one storefront building, 4 warehouses and some retention ponds, which I am still working on, the water looks goofy.  Terrain is hilly, this is Austin.  This is the first project I have done with this big of a terrain perimeter...luckily with the experts here I got rid of my floating warehouses and made separate plans for the warehouses, exported them as 3DS files and imported them in to the master plan.  The storefront and roadways/parking lots, terrain perimeter, landscaping (or my attempt at it), ponds and cars are  in the original .pln.  

 

I think I have to change my signature to include "CA Forum ROCKS"  :)

could you zip and attach your materials from that export...specifically looking for the tree's textures

I found most of what I needed. here is a rendering with alpha mask for backdrop:

Let me know what tweaks you would like and I'll adjust and do one more pass

thank you!  So it is some artifact in the ray trace.  I started tinkering with Thea.  Looks like I am going to tinker some more.  Everything looks more realistic, the cars look great.

NO tweaks.  But here is a backdrop just FYI.  Sincerely appreciate it.

you could make it look 100% real with 80 more hours, haha..but that's usually not worth the time spent

Looks like another rendering technique will be needed for large areas, so "Learn Thea Rendering" has now moved up on my TO DO list!

If you need to in the Future , Use Chief's own  Backup Entire File Option on the File Menu, it will zip the .plan up with all the Textures Used in the .plan file.

 

Not sure if it still helps in CA , but they have always advised starting drawing near 0,0, (Origin) , so I placed and Input Point in my Template Plan so I am always close to  0,0 in the bottom LH corner of my window.

 

CA Released new Materials and Core Libraries today , if you didn't see the Announcement , run the Update Catalogs command, under the Library Menu.

      Hi All, I am trying to achieve a ray trace with a tree in the foreground that sort of frames the picture. Attached is an example of my goal- I did not create the attached jpg. I am getting close by placing a tree close to the camera but mostly out of view, but every tree I have tried is blurry. See the saved camera in the attached file. Then I place another big tree closer to the house to create a shadow on the house/driveway. I will crop that tree out of the final picture. Are there any trees CA has that you recommend for close-up high resolution (5500x3200 pixels) ray trace? I found a thread from the old Chief Talk where they had a similar problem and Larry Kumpost  suggested a high res tree, but I don't know where to find one. Here is the old thread http://www.chieftalk.com/showthread.php?34289-Exterior-Critique&highlight=trees+foreground. Thank you in advance!

      Can anybody tell me why I get ray traces that are really grainy?  I can't find a topic on this.  I am using X9 on a mac.

      When doing a Ray Trace the cabinets seem to be lit from the inside.
      There were no lights added to these cabinets and it seems to be happening every time.

      How do I get rid of halos/glare that is appearing at crown molding, around door ways, cabinets, etc. in ray trace view? Do I need to change the default for interior ambient light?
