This might be helpful for beginners.
My question is: where is ktxTexture_Destroy is defined? It’s declared in ktx.h.
what file is the base project?
Yes! It is defined in ktx.h which is included in the base project: Vulkan/base at master · SaschaWillems/Vulkan (github.com)
I recommend you to download the repo and use
cmake -G "Visual Studio 16 2019" -A x64 from the command prompt to generate the VS project files automatically. Don't create your own project from scratch.
Which file? There is only a header declaration in ktx.h. The body is not defined. Missing a CPP file. which file?
Clone the repo using the command prompt in a folder of your choice (if you don't have git, install it before proceeding)
git clone --recursive https://github.com/SaschaWillems/VulkanFrom the command prompt, enter the Vulkan directory and type the following command (if you don't have cmake, install it before proceeding)
cmake -G "Visual Studio 16 2019" -A x64 If it gives you an error, delete CMakeCache.txt and try the following
cmake -G "Visual Studio 17 2022"Download and extract the following archive in the Vulkan folder (overwrite the data folder)

OK, so I got it to compile and link using my own project, as well as using the cmake-generated project. The app however runs briefly and then exits. I'm not putting the shaders and whatnot in the right directory? The error handling is non-existent.
Yes, it appears that I'm missing the gltf files. Any idea where models/cube.gltf can be downloaded from?
P.S. I found the download_assets.py, and it's downloading now. Thanks for all of your help!
As a consolation I got a spotlight working, by using the code from Vulkan Cookbook ( https://github.com/PacktPublishing/Vulkan-Cookbook ):
I will settle for this code, for sure!
@pam79 Have you played around with this omnidirectional shadow mapping tutorial?
I'm trying to alter the height of the light, and if I increase y, it moves down, and if I decrease y, it moves up. It's backwards. Did you fix this somehow, when you tried it out?
