I was trying to use macro , but it didn't work (or I just don't know how to use :D).

Ressurecting a 10+ year old feature request here:
:banghead:

the particle vortex tool has only a position on-screen widget.
what it desperately lacks is a simple on-screen display widget that indicates the direction of the spin, from it's centre, and an interactive way to indicate its strength and speed. I suggest a simple pair of arrows similar to the universal symbol used for recycling. it could grow in size for example as the power is increased, and shrink in size as it is decreased. for...

Ribbon3D is cool and extremely versatile.
Especially the method of setting an explicit start/end point.
However, the lines are pretty much Fusion-unique, rendered output depends on your graphics card,
and they won't export to OBJ, FBX and the like.

It would be *really* cool if there was an option in Ribbon3D to actually create Cylinders instead of lines.
Basically the same controls we have in Shape3D/SurfaceCylinderInputs.

Alternatively Shape3D/Cylinder could come with an option to use...

Currently, the Camera3D's ApertureW and ApertureH cannot be modified by a simple expression. I am attempting to set the film back dynamically based on an input image's aspect ratio.

Scutoids are a geometrical solution to three-dimensional packing of epithelia.

Just because we could, and I would love to see Fusion being the first :D

Many (most) 3D Trackers have the capability to create supervised tracking points, set by and adjusted by the user, in order to supplement and/or guide auto-tracking. Fusion's Camera Tracker would benefit from the ability to add existing point tracks and paths in order to supplement the data produced by automatically generated trackers.

An example of PFTrack's User Track node, followed by an Auto Track, showing both types of tracking points.

PlanarTracker is doing an awesome job.
But sometimes when I use it for CornerPinning, I want to have access to the X/Y coordinates
of the individual TopLeft/TopRight/... points.
i.e. the tracked position of those points, not the values I set at the refFrame.

The PlanarTracker already knows where the CornerPin lives,
so it would be great to gain access to those 4 coordinates directly.

It would be really great to have a grain removal tool in Fusion just like Nuke's Denoiser Node. The Remove Noise node in Fusion just doesn't do the trick. I know we can always count on third party plug-ins or apps to get the job done, but I really wanted to have it without the need to spend almost the price of a Fusion Studio license in a plug-in like NeatVideo just to deal with grain!

Imagine having an 8k x 8k Elevation map of some terrain.
To utilize this for a proper Displace3D on a plane, the plane's Subdivs
need to be set to 8191 x 8191, to reflect every single pixel in the map.

This, naturally, brings Fusion down on it's knees, even with a Titan Card installed.

However, in the map there are huge areas of the same color (i.e. of the same terrain height)
If one now could generate an intelligent SubDivision in Fusion that would be more than awesome.
So some sort of...
