Hi - I continue to enjoy learning from Metal by Tutorials with the 2nd Edition!
I have begun to adapt the Ray Tracing Project ( Chapter 21 ) to handle vertex connecting & merging which has opened up a bunch of new ideas and questions, but when I loaded my project onto a recently purchased 16" MacBook Pro, I got a crash when “rebuilding” the MPSTriangleAcclerationStructure during the initial setup.
I thought I had broken the vertex buffer.
Next, I tried a fresh copy of the Ray Tracing project from Metal by Tutorials, I got the same issue - There is a complete freeze up at the acceleration structure rebuild call.
The installed Catalina OS and Xcode are fully up to date. Is this a real issue and if so, could there be a work around? It is tragic not to be able to try these things right now.
Thanks again for all of the care put into your publications,
