Following up the previous post. I added HDR image import, BC6H compression and cubemap tool this time. Also integrated the ImGui as current GUI solution. To be honest, there are more refactoring and bugfixes in this sprint and only a few runtime features. But I think it's also important to review the code sometimes and refactor them at a certain point. In case making the project as an incomprehensible pain. *Disclaimer: This is just a personal practice of engine programming.
