If you meant "PS" (Photoshop) or just want a review of the Radial Blur filter in general design:
If this is a specific, obscure VST plugin named exactly "FL Radial Blur" or similar: It is likely a "toy" plugin or a specific script (like in Flowstone/Synthmaker) shared on forums. These tend to be CPU-heavy and unstable but offer unique, glitchy textures.
Could you clarify which software or plugin you are referring to? I can then give you a more specific technical review.
The Radial Blur effect (often prefixed with "FL" in third-party plugin suites like Frischluft) is a versatile tool used in video editing, motion graphics, and photography to simulate high-speed motion, depth, or stylistic distortion. Unlike standard Gaussian blur, which blurs pixels uniformly in all directions, Radial Blur blurs from a central point outward. 1. Primary Types & Modes
Radial Blur typically operates in two distinct modes, depending on the software used:
Spin Mode: Creates a rotational blur around a fixed point, simulating a spinning camera or object.
Zoom Mode: Blurs pixels along lines radiating from the center, mimicking a fast "crash zoom" or high-speed forward movement.
Aberrative Mode (Frischluft Flair): Some specialized plugins like Frischluft Flair include an aberrative mode that separates color channels during the blur for a more organic or "glitchy" look. 2. Key Parameter Controls fl radial blur
To achieve professional results, editors typically adjust the following settings:
Amount: Controls the intensity of the blur. High values can create abstract streaks, while low values add subtle energy.
Center Point: Sets the "anchor" of the effect. In many applications like After Effects, this can be keyframed to follow a moving subject, such as a face or a speeding car.
Quality/Antialiasing: Determines how smooth the blur looks. Higher quality settings reduce "graininess" but increase rendering time.
Grow Bounds: A common troubleshooting tip—if the blur is "cut off" at the edges of a layer, apply a Grow Bounds effect before the blur to expand the workspace. 3. Practical Use Cases
This is an excellent request, as FL Radial Blur is one of the most misunderstood, underutilized, yet uniquely powerful effects in the Adobe After Effects ecosystem (and originally in Final Cut Pro’s FxPlug).
I’ll assume you mean the FL Radial Blur plugin by Flaming Pear (often bundled with their “Glitterato” or found in older effect suites) — not a typo of After Effects’ native Radial Blur or CC Radial Blur. If you meant a different host (e.g., Photoshop, Nuke), let me know, but AE is the most common context. If you meant "PS" (Photoshop) or just want
The FL Radial Blur is a powerful narrative tool, but restraint is key.

Once you add a Radial Blur effect in ZGameEditor, you will see adjustable properties. These may vary slightly by preset, but generally include:
| Parameter | What it does | |-----------|----------------| | Center X / Y | Sets the point from which the blur radiates (0 to 1 range; 0.5,0.5 is center). | | Amount | Intensity of the blur. Higher values = longer streaks. | | Falloff | How the blur fades toward the edges (soft vs sharp radial effect). | | Angle | Direction of the blur (0° = pure zoom out, 90° = circular swirl, etc.). | | Samples | Quality setting – more samples = smoother but heavier on CPU/GPU. | | Opacity | Blend the blurred image over the original. |
Some advanced presets also include:
If you are looking for how fluids handle interpolation or "blobs" of influence (which can look like a blur effect), you are likely looking for Radial Basis Functions. These are used to interpolate velocity fields or create smooth fluid surfaces. If this is a specific, obscure VST plugin
Center Point – Determines the “vanishing point” of the zoom blur. You can animate this for rack-focus effects.
Blur Length – Intensity of the blur (1–100). At 100, edges are completely smeared to infinity.
Quality – Low/Medium/High. High is slow but necessary for 16+ bpc work. Avoid Low except for previews.
Curve – This is the secret weapon. Instead of linear blur falloff, Curve adjusts the radial gradient of blur strength from center to edge. Negative values push blur outward; positive values pull blur inward. This creates ring-like blurs or sharp-center + smeared-edges.
Shape – Circle, Square, Cross, Star, etc. FL Radial Blur can convolve the blur kernel with geometric shapes. “Cross” is great for anamorphic streaks.
Rotation – Rotates the blur kernel shape. Useless for Circle, essential for Square/Cross.
Opacity – Blends original image with blurred result. At 50% you get a “ghost zoom” effect.
| Effect | Settings | |--------|----------| | Spinning vinyl record | Center = record center, Angle = 90°, Amount = medium, Samples high. | | Explosion shockwave | Center = explosion point, Angle = 0°, Amount high, Falloff = sharp. | | Hyperspace tunnel | Center = screen center, Angle = 0°, Amount very high, Falloff = smooth. | | Abstract vortex | Angle = 85°, Center slightly off-center, Amount varies. |
