The disc generator wraps up some common functionality for generating discs for realtime vfx (think AOE’s or muzzle flashes). You can quickly set the inner and outer radius, modify the profile and add noise to shape the disc for multiple usecases. UV’s are automatically laid out and adjusted with override controls. Add vertex colour based on u or v to drive material parameters in your game engine.
Distance from the centre of the object for the inner circle.
Distance from the centre of the object for the outer circle.
Start point of the arc in degrees, relative to the x-axis.
End point of the arc in degrees, relative to the x-axis.
Number of polygon segments around the disc.
Number of polygon segments from the centre to the outer edge of the disc.
Rotate UVs 90
This essentially flips the u and v direction of the uv’s.
U Range And Bias
The first two components set the coverage of the uv’s in the u direction. The third component distorts the uv’s using a power function.
V Range And Bias
The first two components set the coverage of the uv’s in the v direction. The third component distorts the uv’s using a power function.
Height of the inner circle along the y axis.
Height of the outer circle along the y axis.
N Cusp Angle
When computing vertex normals, if normals of vertices around a single point are less than or equal to this angle (in degrees) apart from each other, they will be averaged together, weighted by the vertex angle in each polygon.
Increase or decrease the effect of the profile ramp.
Use the ramp to modify the shape of the disc.
Enable perlin noise distortion of the geometry.
Scale the noise independantly in each axis.
The number of composited noise layers.
Add UV Noise
Distort the uv’s with noise.
Frequency of the noise in texture space.
Offset the noise position.
UV Noise Intensity
Displace amount of uv’s.
Create a vertex attribute, Cd.
V Colour Ramp
Switch the ramp from using the u direction to the v direction of the uv’s.
