Chunky is an open-source desktop path tracer for rendering Minecraft worlds from selected chunks, using camera, lighting, sky, water, texture, and sampling controls to produce still images for builders and content creators.
Chunky is the stronger choice when the source of truth is a Minecraft Java world and you need physically based still images of exact block layouts. RENDERCAD fits a different job: turning a viewport, screenshot, blockout, or design image into a polished concept render quickly without loading a world file or managing samples. Use Chunky for faithful Minecraft-world path tracing; use RENDERCAD for presentation visuals, architecture concepts, or product-style imagery from image input.
Chunky starts with Minecraft world and chunk data, then asks the user to choose chunks, camera position, lighting, sky and fog, water, materials, and sampling targets. Because Chunky path traces locally on the CPU by default, image quality improves over time and noisy lighting can require longer renders. That makes it useful for builders who want reproducible still renders of block worlds. RENDERCAD does not replace that world-file workflow: it works from a screenshot or viewport and is better for fast visual reinterpretation, design review, or marketing-style stills when precise Minecraft block fidelity is less important than a polished output. Choose Chunky when you need accurate Minecraft scene rendering; choose RENDERCAD when you want a lower-setup image-to-render workflow across design sources.
Screenshot the CAD viewport you already have, render in the browser, and download a client-ready still or video without exports, plugins, or GPU setup.

Get StartedCommon questions about RENDERCAD vs Chunky (Minecraft)
No. RENDERCAD runs on cloud GPUs, so you can render 4K images on a basic laptop or even a Chromebook. Your computer never slows down.
RENDERCAD still-image jobs usually complete in about 10 - 60 seconds. Competing renderer speed depends on scene complexity, render settings, hardware, queue time, and final output quality.
RENDERCAD starts at $20/month with credits that refresh monthly - predictable costs with no upfront investment or perpetual license fees.
RENDERCAD works from 2D images. Upload a CAD screenshot, real photo, or hand drawing - no file conversion, no exports, no compatibility issues.
Yes. RENDERCAD understands materials semantically - it knows what brushed aluminum should look like without you defining roughness values, IOR, or shader parameters.
RENDERCAD excels at rapid client presentations. It delivers impressive photorealistic results in seconds, enabling real-time feedback sessions during design reviews.
With RENDERCAD, upload your image or snip your screen, type "Carbon Fiber" in the prompt, and the AI retextures your image realistically in 10-60 seconds. No UV mapping or texture coordinates required.
Yes. Select the Realistic engine, set Condition to Clean, and type "Brushed Aluminum." The AI applies correct texture orientation to your geometry automatically.
Prompt "Sunny Forest" or "Urban Street" and RENDERCAD generates a matching environment in 10-60 seconds. No scene file or environment map setup.
RENDERCAD handles studio lighting automatically - select a Gradient or White background for a clean studio look. No manual light placement or HDRI setup needed.
Yes. The Gentle Orbit camera setting generates subtle rotation from a single static image automatically.
Yes. The Seamless Loop option ensures the last frame matches the first for perfect looping - ready for social media, websites, and displays.
