Project Overview
I need a high-quality, photorealistic 3D render of a unique center-weighted shaker whisk called the Barbell Blender™.
This is a weighted whisk used inside a premium protein shaker bottle. The product already exists, and I attached a .STP file and a quick video of the outside. This contest is not for redesigning the product. The goal is to create a polished, premium product render that clearly shows the internal stainless-steel weighted core.
The final render will be used in Amazon listing images, product graphics, website visuals, and marketing materials.
The most important deliverable is a clean, realistic cutaway render of the center housing showing the stainless-steel core inside.
⸻
Main Goal
Create a premium render that communicates:
WEIGHTED CORE. COMPACT SIZE.
STAINLESS-STEEL CORE
The viewer should instantly understand that the whisk has a weighted stainless-steel core inside the center section, while the overall whisk remains compact and normal-looking.
The render should feel like high-end studio product photography or premium engineering visualization, not a raw CAD screenshot.
⸻
Files Provided
I will provide:
* STEP file of the Barbell Blender™ weighted whisk
* Current rough render / mockup reference
* Bottle render for scale/context only
* Product/material notes
* Any additional references needed during the contest
The bottle is not the focus of this contest. Please focus on the whisk only.
⸻
Required Deliverables
1. Hero Render of Full Whisk
Create a clean, premium render of the full Barbell Blender™ weighted whisk.
Requirements:
* Full whisk visible
* Wire coils intact
* Center weighted housing clearly visible
* Realistic stainless-steel wire material
* Realistic HDPE outer shell material
* Premium studio lighting
* White or transparent background
* Suitable for Amazon product images
⸻
2. Cutaway Render Showing Stainless-Steel Core
This is the most important deliverable.
Create a version of the whisk where the center housing is partially opened to reveal the stainless-steel core inside.
Important Cutaway Direction
Please do not cross-section the entire whisk.
Please do not cut the wire coils.
Please do not make the product look broken.
Only create a clean reveal window in the center housing / barrel of the whisk.
The cutaway should remove about 25–35% of the visible front shell of the center housing. The goal is to show the stainless-steel core inside while keeping the product looking finished, premium, and realistic.
The wire coils should remain intact and can naturally pass in front of the cutaway. That is okay, as long as the stainless-steel core remains clearly visible.
The cutaway should look like a premium engineering/product visualization, not like a damaged product.
⸻
3. Two-Whisk Render
Create a render showing two Barbell Blenders™ together.
This will be used to show that the 2-pack product includes two weighted whisks.
Requirements:
* Two whisks visible
* Slightly different angles
* Realistic shadows
* Realistic metal reflections
* Not floating
* Clean white or transparent background
* Suitable for Amazon main image use
⸻
Material Requirements
Wire Coils
Material: Stainless steel wire
The wire should look realistic and premium.
Please show:
* Metallic reflections
* Round wire shape
* Smooth highlights
* Depth between coils
* No flat gray CAD material
* No jagged or rough edges
⸻
Internal Weighted Core
Material: Stainless steel
The internal core should look solid, heavy, and metallic.
Please show:
* Brushed or satin stainless-steel finish
* Realistic silver metal color
* Solid weighted appearance
* Subtle highlights and shadows
* No artificial color
Please avoid:
* blue core
* pink core
* rainbow core
* glowing core
* sci-fi x-ray look
* transparent neon effect
The core should look like a real stainless-steel insert inside the center housing.
⸻
Outer Center Housing / Shell
Material: HDPE
Finish: somewhat glossy molded plastic
The shell should look like real molded HDPE plastic. It should not be mirror-gloss, but it should have a soft gloss/sheen with realistic highlights.
Please show:
* Slight gloss, not mirror finish
* Real molded plastic look
* Clean bevels and edges
* Subtle surface realism
* Correct wall thickness in the cutaway
* Soft highlights
* Premium product quality
Please avoid:
* flat matte CAD look
* toy-like plastic
* mirror-gloss plastic
* rubber-like material
* glass-like material
⸻
Cutaway Detail Requirements
For the cutaway/core reveal, please show:
* Realistic outer shell thickness
* Clean beveled cut edges
* Subtle internal shadows
* Stainless-steel core recessed inside the housing
* Realistic material boundaries between shell and core
* The product still looking whole and premium
The cutaway should look intentional, like a clean product visualization.
It should not look like the whisk has been broken, sliced in half, or damaged.
⸻
Composition Direction
The render should be large, clear, and easy to use in Amazon listing images.
Preferred look:
* Large whisk centered
* Clean white or transparent background
* Room above for headline text if needed
* Room on the side for a small callout label
* Product well-lit and premium
* No clutter
* No lifestyle background
The cutaway version should make the stainless-steel core obvious without overcomplicating the render.
⸻
Visual Style
The final render should feel:
* premium
* clean
* modern
* realistic
* engineered
* Amazon-ready
* high-quality
Think:
premium product photography + clean engineering visualization
Not:
raw CAD screenshot
⸻
Lighting Direction
Please use clean studio product lighting.
Suggested lighting:
* Soft key light from upper front-left
* Soft fill light from front-right
* Subtle rim light if needed
* Realistic reflections on metal wires
* Soft shadows under product
* Clean white or transparent background
The lighting should make the stainless steel and HDPE materials look realistic and premium.
Evaluation Criteria
I will choose the winner based on:
1. Photorealism
The render must look premium and realistic, not like a raw CAD export.
2. Cutaway Quality
The cutaway should clearly reveal the stainless-steel core while keeping the product looking whole and premium.
3. Material Accuracy
The stainless-steel wire, stainless-steel core, and HDPE outer shell must look believable and high quality.
4. Amazon Usefulness
The render must be clear, easy to understand, and suitable for Amazon listing images.
5. Premium Product Feel
The whisk should look like a finished premium product, not a prototype or low-quality render.
6. Source File / Workflow Quality
Please state the software used and provide source/render scene files if possible.
What I Do Not Want
Please avoid:
* cutting the entire whisk in half
* cutting through the wire coils
* making the product look broken
* fake glowing core
* colored/rainbow core
* rough CAD screenshots
* unrealistic metal
* flat gray materials
* harsh shadows
* overly dark render
* cluttered backgrounds
* adding text directly into the render unless requested
* changing the product design
* making the whisk look oversized or distorted
Sample Submission Requirement
For initial contest entries, please submit at least:
1. One full hero render of the whisk
2. One cutaway/core reveal render
The cutaway render is the most important part of this contest.
You do not need to complete every final export in the first submission, but I need to see your rendering quality, material realism, and approach to the stainless-steel core reveal.
