Last verified July 23, 2026. Product names, prices, and compatibility can change.
There is no current Rocket Lasso product called “Chop Chop” on the developer’s official shop. The matching tool is RKT Slicer, a $97 Cinema 4D plugin that makes procedural parallel cuts through meshes. Rocket Lasso describes it as a way to “chop up” meshes, which likely explains the working title.
This review keeps the requested page title for search and editorial continuity, but the product readers can actually buy is Slicer for Cinema 4D. That name should appear in purchase buttons, schema, and image captions. The current product identity should not be blurred for the sake of a catchy heading.
Slicer is also not a broad Boolean suite. It creates a controlled family of parallel sections and can return them as splines, flat sheets, extruded layers, or alternating layered structures. If that is the modeling operation you repeat, Slicer is precise and useful. If you need arbitrary object-on-object subtraction, union, or mesh cleanup, look elsewhere.
What Slicer does
Slicer takes a source mesh and intersects it with a sequence of parallel cutting planes. The generated sections can remain as curves or become several geometry styles. The official product page lists:
- Spline output
- Flat sheet output
- Extruded layers
- Alternating layer structures
- Smoothing for rough cut lines
- Expand controls that inflate or deflate the slice profile
- Offset and looping Rate animation
- Built-in random color, grayscale, Matrix Object, or source-display-color options
- Compatibility with Cinema 4D Soft Body Colorize for spline segments
These outputs are valuable because they remain procedural. An artist can change the source object, slice direction, spacing, count, thickness, or animation without rebuilding every cut by hand.
Rocket Lasso’s public storefront lists Slicer at $97. The exact current build and official Cinema 4D 2026 compatibility were not stated in the checked product text: [VERIFY: current RKT Slicer version and Cinema 4D 2026 compatibility before publication].
It is a sectioning tool, not general Boolean modeling
The phrase “Boolean and modeling workflow” can set the wrong expectation. A Boolean generator combines arbitrary solid operands. It can cut holes, join meshes, subtract one complex object from another, or find their intersection.
Slicer repeats one organized operation: parallel sections through a source mesh. That operation overlaps conceptually with cutting, but it serves a different design purpose. The result resembles contour maps, product cross-sections, stacked layers, scan lines, and architectural slices.
This narrower scope has an advantage. General Boolean systems must account for many topology combinations. Slicer can focus its interface and output modes on repeated sectional geometry. It is easier to art-direct a stack when spacing, direction, smoothing, expansion, layer style, and animation live in one generator.
Do not buy it to fix bad topology or replace Cinema 4D’s Boole object. Buy it to generate a procedural slice system.
Where Slicer is useful
Product visualization
A product can be revealed through moving sections. Flat layers can spread apart to show structure, then return to the full silhouette. Extruded slices can receive different materials or colors. Alternating layers can create a manufactured or 3D-printed look.
Because the slicing is parametric, model revisions are less disruptive than a manually cut stack. The source changes and the section generator recalculates. That is valuable in client work, where a product mesh may arrive late or change after animation has started.
Motion graphics
Slicer’s built-in Rate animation can offset and loop the cuts. This supports moving scan effects, contour waves, repeating layer reveals, and interface graphics. Spline output can feed Sweeps, Hair, Sketch and Toon, or third-party render tools.
The plugin’s color controls can create per-segment variation. A Matrix Object output also connects the slices to MoGraph-based shading or animation workflows.
Fabrication-style forms
Flat and extruded layers can resemble stacked card, plywood laminations, CNC sections, or topographic models. The visual language is useful even when the final piece will never be manufactured.
Artists should not assume the generated geometry is fabrication-ready. Real-world output has constraints around scale, watertight geometry, tolerances, material thickness, and tool paths. Export and validate in the relevant manufacturing software.
Technical and interface graphics
Parallel cuts communicate internal structure. Spline output can be styled as thin diagnostic lines, while extruded output can become a layered technical illustration. Animated offsets produce scan-like motion without simulating a scanner.
The result can look generic if the only idea is “slice the object.” Combine section direction, material rhythm, selective visibility, camera angle, and timing with the design’s actual message.
Output modes and downstream tools
Spline output is the lightest and most flexible starting point. Splines can drive Sweeps, Hair, Sketch and Toon, MoGraph, or other Rocket Lasso tools. They also make the cut pattern readable without filling every section.
Flat sheet output turns the cross-section into a surface. Extruded layers add depth and give renderers proper side faces. Alternating layers create more complex patterns without manually separating every other section.
The best mode depends on the final shot. A distant contour effect does not need thick geometry. A macro product shot may require beveled, shaded layers. Build the cheapest representation that survives the camera and lighting.
Once the result is approved, consider making an editable duplicate for delivery. Keep the live Slicer object in an archive scene so later model changes can be accommodated.
Smoothing and expansion
Section curves inherit the source mesh’s resolution and topology. A coarse or uneven model can produce jagged cut lines. Slicer’s Smooth parameter cleans the generated curves, while Expand moves the section profile inward or outward.
Smoothing is not a substitute for an adequate source mesh. Too much can erase intentional corners or change the silhouette. Test a few representative slices at final resolution.
Expand is useful for creating breathing room between alternating layers, compensating for Sweep thickness, or exaggerating the source form. Extreme values can cause self-intersections or unexpected collapses in tight concave regions. Inspect the full animation, not just the cleanest frame.
Animation and looping
The built-in Rate parameter offsets the slices and can loop the motion. This is one of Slicer’s clearest advantages over a manual stack. The timing remains part of the generator, so spacing or object changes do not require retiming dozens of pieces.
For a perfect loop, confirm:
- The project frame rate and final frame range.
- The Rate cycle length.
- Whether the final frame duplicates the first.
- Motion blur behavior on fast slice movement.
- Any downstream effector or material animation that must share the cycle.
A generator can loop mathematically while the rendered edit still bumps at the cut point. Review the compressed delivery format as well as the Cinema 4D viewport.
Materials and rendering
Slicer generates Cinema 4D geometry or spline structures that can participate in ordinary material workflows. The official product page highlights per-segment color options and display-color input.
Renderer-specific material behavior is not summarized on the checked page. Before production, test the chosen output with Redshift, Octane, Arnold, or another engine. Confirm per-segment color access, motion blur, instances or Matrix data, and any conversion step.
Spline rendering varies by renderer. A Sweep is a predictable fallback when a native spline-rendering path is unavailable or behaves differently on a farm.
Performance and topology
Performance depends on source complexity, slice count, smoothing, output type, and downstream generators. Hundreds of spline contours are cheaper than hundreds of heavily beveled extrusions with unique materials.
Keep the source mesh clean and use a proxy during look development. Increase slice density only when the camera reveals the difference. If an animated generator becomes expensive, cache or convert an approved version while preserving the live setup elsewhere.
Generated topology should be judged by the next operation. A render-only layer may be fine as produced. A deformed, subdivided, or exported layer may need cleanup. Slicer’s promise is procedural section generation, not hand-modeled quad topology for every downstream purpose.
Slicer versus native Cinema 4D
Cinema 4D can create sectional effects with Boole, Volume Builder, Cloners, Fields, Python, Scene Nodes, or repeated planes and splines. Those methods can be more flexible and carry no plugin dependency.
Slicer’s advantage is packaging. The repeated cuts, output forms, smoothing, expansion, color logic, and loopable offset are presented as one maintained generator. That saves setup time and makes a common design operation easier to revise.
The purchase makes sense when the team has built this rig more than once. If the need is a single static set of sections, native tools may finish the job before a plugin evaluation is complete.
Licensing and support
Rocket Lasso sells Slicer through Gumroad for $97 on the checked date. The company says its plugins are sold without subscriptions and advertises a 60-day, no-questions-asked refund policy.
Compatibility and installation details should be verified on the current Gumroad download or support page before upgrading Cinema 4D. Plugin objects can prevent a collaborator from editing the source scene if the plugin is missing, so include the dependency in handoff notes or provide converted output.
Rocket Lasso offers a technical-support page and free training content. That matters for a specialized generator because the best results often come from combining it with MoGraph, Fields, splines, renderers, and other Cinema 4D systems.
Who should buy it
Slicer fits motion designers, product-visualization artists, and technical-graphics teams that repeatedly create sectional, contour, scan, or layered-mesh effects. It is especially useful when the source model is likely to change after the procedural look is approved.
It is not a good fit for artists who need a full Boolean toolkit, mesh repair, retopology, arbitrary cutting planes, or general hard-surface modeling. It is also hard to justify for one static slice effect that can be made quickly with native tools.
Pros and cons
Pros
- Creates adjustable parallel slices without manually cutting and organizing geometry.
- Supports splines, sheets, extrusions, and alternating layer outputs.
- Smooth and Expand controls address common section-curve problems.
- Built-in offset and Rate controls make looping slice animation direct.
- Color and Matrix-oriented options connect the result to motion-graphics workflows.
- A permanent $97 license is easy to evaluate against repeated paid work.
Cons
- “Chop Chop” is not the current product name, which can confuse buyers.
- Slicer is not a general Boolean or modeling suite.
- Current build and Cinema 4D 2026 support need confirmation from the live download.
- Dense extruded outputs can become heavy.
- Procedural plugin objects add a handoff dependency.
- Smoothing and expansion cannot repair every issue in a poor source mesh.
Verdict
RKT Slicer is a good focused purchase for artists who regularly turn meshes into animated stacks, contour lines, layered product forms, or scan-like graphics. Its value comes from keeping the complete sectioning system procedural, including output style, smoothing, expansion, color, and timing.
It should not be marketed as a universal Boolean tool, and it should not be published under “Chop Chop” without explaining the actual product name. At $97, Slicer earns its place when parallel sectioning is a recurring client request. For a one-off cut, Cinema 4D’s native tools are the sensible first attempt.
