Hello, everyone
I am pretty new to Vulkan, so I have three simple questions
-
Are there cases such that obj or bin (in gltf) files don’t have normal vectors ?
-
If yes, is it possible for me to create light (diffuse, ambient etc) or do ray tracing etc on materials inside (without normal) ?
-
What are standard or well-known free tools which edit obj files or gltf (bin) files ?
Thank you and have a nice day
