Should use lastest ImGUI version to avoid strange 'Validation Error: [ VUID-VkMappedMemoryRange-size-01389 ]', please refer to this.

This says to use in target_sources the files "${CMAKE_CURRENT_SOURCE_DIR}/imgui/imgui_impl_vulkan.cpp" and "${CMAKE_CURRENT_SOURCE_DIR}/imgui/imgui_impl_sdl.cpp". With the current imgui that should be "${CMAKE_CURRENT_SOURCE_DIR}/imgui/backends/imgui_impl_vulkan.cpp" and "${CMAKE_CURRENT_SOURCE_DIR}/imgui/backends/imgui_impl_sdl.cpp".

[CarloWood]

Also, "${CMAKE_CURRENT_SOURCE_DIR}/imgui/imgui_tables.cpp" is missing.

The CVAR page is missing a comment section. The CVarArray destructor uses the wrong delete, it should be: delete[] cvars;

Hello, Victor Blanco. I have checked the code repo, but it looks like ImGui is not used there. Any chance you could upload that example code as well? I'm having trouble to get gamma color spaces right with ImGui, and I would like to see how you did it. Thanks!

EDIT: To anyone struggling to get gamma correction working with Vulkan+ImGui: https://tuket.github.io/posts/2022-11-24-imgui-gamma/

What are the steps involved when using something other than SDL?

[Kaninchen221]

I used to this guide to integrate imgui with my vulkan/glfw renderer and the steps are nearly the same

is Dear ImGui compatible with VK_EXT_DESCRIPTOR_BUFFER as of now?
