Box-shaped 3D particle attractor with strength varying within the box, affecting [GPUParticles3D] nodes.
Unlike [GPUParticlesAttractorBox3D], [GPUParticlesAttractorVectorField3D] uses a [member texture] to affect attraction strength within the box. This can be used to create complex attraction scenarios where particles travel in different directions depending on their location. This can be useful for weather effects such as sandstorms.
[b]Note:[/b] Particle attractors only affect [GPUParticles3D], not [CPUParticles3D].
[b]Note:[/b] To get better performance, the 3D texture's resolution should reflect the [member size] of the attractor. Since particle attraction is usually low-frequency data, the texture can be kept at a low resolution such as 64×64×64.
