- [ ] rtx: live rad file reloading (or other solution for tuning lights)
- [ ] rtx: restore studio models
- [ ] rtx: textures
- [ ] rtx: restore dynamic stuff like particles, beams, etc
- [ ] rtx: textures
- [ ] rtx: emissive particles
- [ ] rtx: better random
- [ ] rtx: some studio models have glitchy geometry
- [ ] rtx: simple convolution denoise (bilateral?)
