Every update to POPX.
Full release notes for every version - new operators, fixes, and breaking changes.
- [01] NEW (2)
- → General - Ramps: Phase, Period, Extend Left and Extend Right on the ramp controls place the ramp like a Ramp TOP (Hold, Zero, Repeat or Mirror outside 0 - 1), and can be animated
- → Remesh, Clip, Particle Source, Circle Pack, Planar Patch - Copy Topology Info Back to CPU toggle (off by default, like the Delete POP): copies the real point count and topology back to the CPU so the operators after it allocate only the real size
[02] IMPROVED (3)- → General - The Float and Color ramp editors in every operator are now drawn natively in TouchDesigner instead of a Web Render: nothing cooks while idle, TouchDesigner menus, faster output sampling
- → General - Every ramp now outputs 1024 samples (was up to 32768): lighter, inside the TouchDesigner Non-Commercial texture limit, and an animated Phase costs a fraction of a millisecond per frame
- → Sweep, Instancer, Orient Curve, Move Along Curve, Move Along Mesh, Randomize - Ramps are read with interpolation between samples (smoother twist, scale and color)
[03] PERF (2)- → Nexus, Cloth, Hair - The solver input is compacted to its real point count, so an input whose count stays on the GPU (a Remesh, or a Delete or Topology POP without CPU readback) no longer makes every solver pass copy its whole allocation (Nexus on a remeshed mesh: about 24 ms to 5.5 ms per frame)
- → Voxelize - No longer cooks every frame when its input is not changing (it still follows the timeline while Compute Velocity is on)
[04] FIXED (6)- → Aura - TouchDesigner no longer crashes when a Trail, DLA, DLG or any line or line strip POP is wired into a POPX Geometry while the Aura is running (Aura engine 1.5.0.575)
- → Aura - Viewport on TouchDesigner Non-Commercial: the UI, the render and the output now stay inside the 1280 x 1280 TOP limit (the UI resolution lowers on large panes, the output keeps its aspect)
- → Aura - No textport error when an Aura is deleted while its viewport is running
- → Aura - Removed the Common page: Free Extra GPU Memory had no effect on the Aura
- → Constraints - The Stretch Stiffness and Rest attributes now also apply to Pressure, Shape Match and Triangle Stretch constraints (they had no effect on them)
- → Constraint Property - The maps now reach the pressure and shape match headers (read at the anchor point of each piece), so a map can set the inflate (Rest Length Scale), stiffness, damping and plastic values of a pressure or shape match piece
- [01] NEW (49)
- → General - 38 new operators: POPX now ships 99 operators in six groups (Generators, Falloffs, Modifiers, Tools, Fields, Simulations)

- → Stepper - New modifier that quantizes packed point position, rotation, scale and a float attribute per axis (Floor, Round, Ceiling or Compare), blended by falloff
- → Aura - New Aura Render Engine (Windows, NVIDIA RTX): real-time ray tracing of POPX Geo, Light and Material operators to a TOP, built on NVIDIA OptiX and DLSS, replacing the Path Tracer
- → Aura - Two render modes: Path Tracing (random light paths, one physically based transport for lights, materials, volumes and bounce light) and Hybrid (every pixel lit directly, one ray per effect, clean and deterministic from the first frame)
- → Aura - Denoise for Path Tracing (DLSS Ray Reconstruction, Temporal or Refine) and Antialiasing for Hybrid (Off, FXAA, DLSS, Temporal or Refine); Refine adds Samples Per Frame each frame for stills and video, with Limit Frames, Max Frames and Reset Refine, and traces full light paths in Path Tracing
