Dark Fantasy Themed Lottie Animations

Job ID: 40221065

Budget: €30 – €250 EUR

Project Title: 3 Lottie Chest Animations (1 Base Animation + 3 Variations) - Dark Fantasy Style

Project Overview:
I need a skilled motion designer to create a set of three (3) Lottie (JSON) animations of a treasure chest opening. These will be used in a mobile app with a "Dark Game" aesthetic.

IMPORTANT NOTE ON SCOPE & PRICING:
This is NOT a request for three completely different animations from scratch. The core task is to create ONE SINGLE, high-quality opening animation (movement, timing, physics). This base animation will then be re-skinned with three different textures/colors to create the three variants.
Your quote should reflect the effort of creating one main animation plus the time to apply two texture/color variations, not the price of three separate, unique animations.
Visual Style Requirements (Dark Fantasy/Arcane):
The style should match the "dark game" vibe of the attached reference images. We are looking for:
Heavy Metals: Dark iron, aged gold, polished silver with realistic reflections.

Magical Elements: Glowing runes, embedded gems, arcane energy effects when opening.
Detailed Textures: Not flat or simple cartoon. The wood should look ancient and sturdy, the metals heavy and detailed.
Atmosphere: Moody, mysterious, and powerful.
The 3 Variations Needed (Same Animation, Different Skin):

Wood Chest (The "Base"):
Dark, aged wood with iron or dark steel banding.
Perhaps some subtle, glowing runes etched into the wood or metal.

Silver Chest:
Made of heavy, polished silver or chrome.
Could have blue or white glowing gems/runes, similar to the reference images.

Gold Chest:
Rich, ornate gold texture.
Should feel luxurious and powerful, possibly with green or gold glowing elements.

Technical Specifications:
Format: Lottie JSON files (must be lightweight and performant).
Frame Rate: Smooth animation (30 or 60 fps).
Background: Transparent.
State: The animation should play once and end on the "open" state, or loop perfectly if designed that way (please specify in your proposal).
Deliverables:

3 separate Lottie JSON files (e.g., chest_wood.json, chest_silver.json, chest_gold.json).
Source files (After Effects .aep + Illustrator .ai) are highly desired for future edits.
