The time has come where VectorayGen 1.03 has been released!

Changelog:

• The "Mesh" node has been added. This lets you generate vectors that go around meshes as a pseudo-airflow. You can import .obj and.fbx files and it is similar to the SDF node. The meshes are saved with the projects/presets, so it doesn't read from the local file once its imported and saved.
• The software now automatically checks for updates on startup.
• A 'tightness' parameter has been added, similar to Unreal Engine. A tightness of 1 means the vector field is a velocity field while a tightness of 0 means that it is an acceleration/force field.
• We have moved to a new licensing system. There is now a 14 day trial instead of a maximum number of charges. License verification is now more robust and has a grace period for a couple of days until it has to checked again. You cannot save projects during the trial, but you can export as many vector fields as you want.
• [BREAKING]: Changed internal coordinate system to centimeters. Vector lengths are now in cm/s, i.e. a value of 100 means 1 m/s. This means old project presets and settings will be wrong.
• [BREAKING]: The Fade node now has a fourth parameter, a length scale. For the math inclined, the formula for the length of the vector is now min + (max - min)*(distantlength)^exponent. I.e. if min = 0, max = 100, length = 256 and exponent = 1, then the length of a vector will be 100 at a distance 256 cm away from the center.
• SDF node added, generating flow around prefab objects. Spheres, cylinders, and boxes.
• SDF node is now saved and loaded properly.
• Key binding for SDF node added.
• You can now drag-and-drop projects and presets in the node graph!
• You can now export to more coordinate reference lengths: mm, cm, m, inches and feet.
• The spotlight is now tethered to bounding box, placed a certain distance below it at all times.
• The slicing option was moved from Preferences to both Vector and Particle settings.
• Fixed a bug where connecting nodes in certain configurations failed, where a cyclic graph was erroneously detected.
• Keybindings for the Noise and Mesh nodes were added.
• Lots of backend cleanup.
