TouchDesigner equivalents cheat sheet

For readers who know TouchDesigner and want to know what to reach for. names come from general TouchDesigner knowledge, not from the plugin source.

You would normally use ...	Harlow operator	Notes
Geometry COMP + PBR MAT / Phong MAT	HRLW Geometry POP	Feed it POPs. Material parameters are on its Material page, texture maps on its Maps pages.
Render TOP	HRLW Path Tracer TOP	Reads your Camera COMP, Light COMPs, Ambient Light COMPs and Environment TOP.
Camera COMP	still the Camera COMP	Its View page drives the render (FOV, projection, window).
Light COMP / Ambient Light COMP	still the same COMPs	Read directly, no helper DAT.
Environment Light COMP / Environment TOP	Environment TOP field + Sample Environment as Light	A lat-long HDRI.
Bloom TOP, Lens Distort TOP, Level TOP	Post page	Bloom, flare, chromatic aberration, distortion, vignette, sharpen, grading, grain run on the HDR image before the tonemap.
Bullet Solver COMP + Actor COMPs	HRLW Bodies POP	A POP of points = bodies; joints are a second POP.
(no equivalent) Voronoi prefracture	HRLW Fracture POP	Wire it ahead of HRLW Bodies.
Particle POP / custom GLSL liquid	HRLW Liquid POP	A full FLIP solver.
(hand-built spray/foam particles)	HRLW Whitewater POP or Whitewater Direct
GLSL TOP + Feedback TOP 3D smoke	HRLW Volume Solver TOP	POPs drive it.
Force POP / Collider POP	still the same POPs	Shared by Liquid, Volume Solver and Bodies.
Attribute POP, Constant POP	still the same POPs	Use them to set `materialid`, `pscale`, `v`, `fuel` ... on points and primitives.
Geometry COMP instancing	HRLW Bodies Points output / third-input meshes	Instances are matched by `meshid`.
Render Select TOP, GLSL TOP, Feedback TOP	same, plus HRLW Surface TOP and HRLW Seam Fill TOP	For UV-space simulations.
