-- gltf models
+- glTF models
 - 1 realtime light
 - Simple wgsl preprocessor for includes
 
+Things I would like to add:
+- Shadow mapping
+- Restructuring
+    - Simplify/abstract renderpasses; will be nice to have for PP and GI

+- SSAO
+- Bloom
+- Immediate mode UI (dear imgui, egui)
+- Editing material properties, lights at runtime through UI
+- Some type of GI (DDGI, VXGI)
