Chopsaw Posted March 23, 2018 Share Posted March 23, 2018 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. Link to comment Share on other sites More sharing options...
pgjacob Posted March 23, 2018 Author Share Posted March 23, 2018 I just upgraded recently. I attach the screenshot of the version. Link to comment Share on other sites More sharing options...
KirkClemons Posted March 23, 2018 Share Posted March 23, 2018 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.

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" melissa CA_Thea_no_terrain.zip Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...
pgjacob Posted March 23, 2018 Author Share Posted March 23, 2018 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. melissa Link to comment Share on other sites More sharing options...
pgjacob Posted March 23, 2018 Author Share Posted March 23, 2018 NO tweaks. But here is a backdrop just FYI. Sincerely appreciate it. Link to comment Share on other sites More sharing options...

pgjacob Posted March 23, 2018 Author Share Posted March 23, 2018 Looks like another rendering technique will be needed for large areas, so "Learn Thea Rendering" has now moved up on my TO DO list! Link to comment Share on other sites More sharing options...

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.
