Mega Candles Pack

Setting up atmospheric scenes often demands a large volume of light sources that can be scattered across environments without overwhelming performance or requiring individual placement tweaking. Mega Candles Pack addresses this by providing 1000 high-quality candle models, divided equally between 500 models with simple integrated fire and 500 models without fire. Accompanying the static meshes are customizable materials for wax and wick behavior, along with Niagara particle systems and example blueprints to handle dynamic smoke, fire, and light flickering.

Wax and Wick Material Implementation

The candle wax material relies on subsurface scattering to simulate the way real wax absorbs and transmits light from a nearby flame. A specific wax SSS feature is built into the material, paired with an adjustable SSS glow effect that simulates the illumination bleeding into the wax directly from the candle flame. This allows artists to control how strongly the fire impacts the appearance of the wax body, making it possible to tune the glowing effect based on the ambient lighting of the scene.

Separate from the wax, the candle wick material provides controls over the ember state of the wick itself. Developers can adjust the glow power to increase or decrease the brightness of the burning tip. The material also includes an option to extinguish the wick completely, which is useful for placing candles that have been recently blown out or have burned down without sustaining an active flame.

Integrated Flames and Random Motion

The 500 candle models included with simple integrated fire use a non-dynamic flame representation built directly into the geometry or material. Because these integrated flames are simple and not dynamic, they are intended for background candles where performance is a priority over complex simulation.

For hero candles that require a more prominent and realistic fire, the pack includes a Niagara fire particle system. Creators can swap the simple integrated visual for this Niagara system on select candles. Despite the simple integrated flames being non-dynamic, they are programmed to move randomly. The movement of all candle flames is calculated depending on their position, creating organic variation across a scene filled with numerous light sources.

Adjustable Flame Color Variation

When dealing with a large number of light sources, visual repetition can become apparent. To counter this, all candle flames feature an adjustable color variation option exposed in the material. This parameter gives developers the ability to introduce subtle or distinct shifts in the fire's hue across different candles, breaking up uniformity and allowing for different candle materials to be distinguished from one another.

Niagara Particle Systems and Example Blueprints

Beyond the integrated fire visuals, the pack supplies two distinct Niagara particle systems to expand the physical behavior of the candles. The first is a Niagara fire particle system intended for dynamic, high-fidelity flame generation. The second is a Niagara smoke particle system, which provides the trailing or lingering smoke effects associated with burning wicks.

To demonstrate how these systems can be assembled, the pack includes 10 example blueprints of candles emitting smoke. These blueprints serve as ready-to-use reference implementations, showing how the smoke particle system can be attached to the candle models to create a continuous burning effect in a scene.

Flickering Light Blueprints and Lightmap UVs

Following Update 1.01, the pack added a random flickering light blueprint. This component simulates the natural shifting of a flame's light intensity, casting moving shadows and varying illumination that mimics real fire behavior rather than relying on static point lights. Applying this blueprint to the candle models helps integrate the lighting with the randomly moving integrated flames.

From a rendering optimization perspective, all candles have lightmap UVs. The inclusion of these pre-computed UV coordinates ensures that the static geometry of the candles can capture baked global illumination and shadow information accurately, which is beneficial when placing the 500 models without fire or when baking ambient occlusion into a scene heavily populated with candle props.

Project Placement and Thematic Application

The visual identity of the assets leans into Fantasy and Medieval themes, suitable for ancient dungeons, castle interiors, ritualistic environments, and tavern settings. The variety provided by the 500 models with fire and 500 models without fire allows level designers to populate broad areas with active light sources while using the unlit variants for debris, spent candles, or environmental dressing that does not contribute to the scene's lighting budget.

The package is structured to handle scenes requiring dense candle placement by combining staticmesh variants, customizable materials, and Niagara components.
