# VFXPreset Performance Optimization ## Overview To use VFX Presets more efficiently, various performance types are automatically determined by combining **Importance** and **Infinite Loop** settings. This allows creators to optimize according to the characteristics of each effect type. Additionally, by managing VFX Presets based on a fixed budget, creators can not only save resources but also **maintain balanced quality and performance** for each effect type. This approach makes it easier and more efficient for creators to handle VFX presets during development. ## VFX Preset Budgeting VFX Presets consume significant device performance. The more they are used, the higher the quality, but this can degrade the play experience due to performance drops. To ensure performance, VFX usage must be minimized, but this reduces the game's visual appeal. To address this, OVERDARE Studio automatically classifies Performance Types based on the Importance and Infinite Loop settings, and allocates resources for each type, providing creators with the ability to easily use VFX while ensuring performance.\\ ### Restrictions

Classification	Restrictions
Budget Update Cycle	Spawn: Updates budget when placed in the world or enabled Tick: Updates budget by calculating priority at regular intervals
How to prioritize within a budget	Distance: Prioritizes display based on proximity to the camera Age: Prioritizes display based on the order of recent spawning
How to handle budget overruns	Kill: Disables rendering (cannot be reactivated) Asleep: Temporarily disabled; can be reactivated when resources are available
Expression Maximum Distance	Exclude from budget if the maximum distance from the camera is exceeded
Maximum Instance Count	Maximum allowed instances per performance type
Maximum Number of Identical Effects	Maximum number of identical effects within the same performance type

### Importance and Performance Type Mapping The Performance Type is automatically determined internally based on the combination of the VFXPreset's **Importance** and **Infinite Loop** settings, as shown below.

Importance	Infinite Loop	Performance Type	Description	Usage Examples
Default	False	Default Burst	One-shot VFX that must be played regardless of performance	Essential visual effects
Default	True	Default Looping	Looping VFX that must be played regardless of performance	Essential looping visual effects
Background	False	Background Burst	VFX that plays at a specific point in the background	Sparks, smoke effects
Background	True	Background Looping	VFX that continuously plays in the background	Torch, rain effects
Gameplay	False	Gameplay Burst	VFX that briefly plays at certain points during gameplay	Hit effects, level-up/item acquisition effects
Gameplay	True	Gameplay Looping	Gameplay VFX that loops continuously	Shield, buff aura effects
Critical	-	Critical	VFX that must be expressed in gameplay	Scoring effects, start/end conditional effects

## Resource Limits by Performance Type ### Resource Limits in General Specifications Options

Limitation	Background Looping	Background Burst	Gameplay Looping	Gameplay Burst	Critical	Default

How to handle exceeding budget	Asleep	Kill	Asleep	Kill	Kill	Kill / Asleep
Maximum expressible distance	10000	5000	10000	12500	No restrictions	No restrictions
Maximum number of instances for that budget	8	8	40	60	20	88 / 48
Limit the number of identical effects	4	4	10	30	20	88 / 48

### Resource limits in low-spec options

Limitation	Background Looping	Background Burst	Gameplay Looping	Gameplay Burst	Critical	Default
Update Cycle	Tick (Medium)	Spawn	Tick (High)	Spawn	Spawn	Spawn / Tick (Low)
Priority Determination Criteria	Distance	Distance	Distance	Age	Age	Distance
How to handle exceeding budget	Asleep	Kill	Asleep	Kill	Kill	Kill / Asleep
Maximum expressible distance	1250	450	2500	1000	No restrictions	No restrictions
Maximum number of instances for that budget	6	6	6	25	4	32 / 12
Limit the number of identical effects	3	4	4	4	2	32 / 12

## How to Use ### Creating a VFX Preset Create a VFX Preset in the Level Browser and adjust the desired effects, color, size, and more.

Decide based on the intended use and importance of the effect you are using. The internal Performance Type is automatically determined based on the combination of Importance and Infinite Loop settings.

### World Layout Place the VFX Preset in the location or area where the effect should appear. If it does not need to be pre-placed in the world but dynamically placed during the game, store it in ReplicatedStorage or ServerStorage and place it in the world using Clone or Parent assignment. ```lua local ReplicatedStorage = game:GetService("ReplicatedStorage") local VFXPreset = ReplicatedStorage:WaitForChild("VFXPreset") local Workspace = game:GetService("Workspace") local Part = Workspace:WaitForChild("Part") local NewVFX = VFXPreset:Clone() VFXPreset.Parent = Part ``` ## Note The Importance of a VFX Preset cannot be changed at runtime. When creating and placing a VFX Preset during runtime, create it in ReplicatedStorage or ServerStorage in advance and dynamically place it using Clone or similar methods.
