MaryAnne Posted August 23, 2017 Share Posted August 23, 2017 In performing a ray trace, my ceilings which are white always come out black. I have tried adding lights with the "light bulb " icon and changing elevations, but this does not work. I have Chief X9. I really need to figure out to solve this issue. Antone have the magic answer?

MaryAnne Posted August 23, 2017 Author Share Posted August 23, 2017 This is a regular picture but in performing a ray trace, I get black ceilings. I saw one post that suggested clicking on lighten ceilings. I don't even know where that "button" is. Any thoughts? Thanks Mary Anne Link to comment Share on other sites More sharing options...
MaryAnne Posted August 23, 2017 Author Share Posted August 23, 2017 I also just clicked on "use Photon mapping" and it made a difference but I do not know what this means and I have tried looking it up but that did not help. What does photon mapping do and it appears that it is not always used???? Link to comment Share on other sites More sharing options...

Kbird1 Posted August 25, 2017 Share Posted August 25, 2017 Perry maybe right X9 has a number of changes under the hood when it comes to the Graphics engine , it's also possible your videocard does not fully support X9 , perhaps call Tech Support and get them to help you check those things out. Things going Black in Raytrace is usually a Metal Material which isn't optimized for Ray tracing eg Chief's old stainless steel material .....I am assuming there is no metal on your ceiling Tiles though Link to comment Share on other sites More sharing options...
