LizArk Ai Render Support

LizArk AI Render is a local AI rendering extension for Trimble SketchUp. It includes four core workflows: Generate (text-to-image), Structure (ControlNet Canny/HED edge-guidance matching your model), Image Edit (brush-mask inpainting), and Enhance (realism upgrades with a built-in structural fidelity guard). Inference runs 100% locally on your PC via an isolated Python runtime with no cloud uploads. Learn more at lizatek.com/products/lizark-ai-render.

Free is keyless (no account or payment needed) and outputs a fixed 512×512 preview (or aspect presets capped at 512 px) with a bottom-right "LizArk Ai Render" watermark, 1 output per job, 1 reference image, 1 brush-mask area, and 6 core style presets. Pro unlocks full 1024×1024, widescreen, and 2K resolution (up to 4096 depending on GPU VRAM), 100% watermark-free output, 1–4 variant contact sheets, 4x UltraSharp neural AI upscaling, multi-reference packs with 5 role tags, 32px directional canvas outpainting, camera/geometry structural preservation guard, full preset library + custom presets, and local prompt search.

LizArk Ai Render Pro is available in two plans: 6 Months ($29 USD internationally or ₹2,999 INR in India) and Yearly ($49 USD/year internationally or ₹4,999 INR/year in India). Both plans include unlimited watermark-free 2K and 4K rendering on your GPU with zero per-image token fees, 4x UltraSharp neural upscaling, canvas outpainting, and multi-reference packs. Checkout is processed via Dodo Payments with local UPI and Cards supported in India. The Free tier costs $0 and requires no payment activation.

Pro removes artificial plan-tier feature and resolution paywalls. Natural physical limits still apply: your GPU VRAM, system RAM, free disk space, installed engine capabilities, and content safety filters. Models are downloaded on demand, not pre-installed.

Currently LizArk Render runs 100% locally on your machine for zero credits, full privacy, and fast offline iteration (including an offline CPU fallback mode). Managed cloud GPU rendering is an active roadmap item slated for upcoming releases to support low-VRAM laptops and ultrabooks.

LizArk Render follows the standard Lizatek refund policy shown at checkout and in our terms at lizatek.com/terms. For refund requests, open a ticket at lizatek.com/support with your order ID.

Yes! LizArk Render includes a built-in offline CPU runtime profile. During runtime setup, select the CPU profile to generate renders locally without a dedicated NVIDIA GPU. While an RTX GPU provides the fastest performance, CPU mode allows full concept testing.

1) Download the .rbz file and install it in SketchUp via Window > Extension Manager > Install Extension; 2) Open LizArk Render from Extensions and click Setup & repair in the Settings drawer — this creates an isolated embedded Python 3.10 runtime in %LOCALAPPDATA%\LizArkRender with hardware-optimized CUDA (RTX 50 or 30/40) or CPU wheels; 3) Open the Models tab to download verified open models (FLUX.2 Klein, Z-Image Turbo, SANA 1.6B) from Hugging Face with pause/resume support; 4) Start rendering immediately.

After buying Pro, go to lizatek.com/license/lizark-render and enter your checkout email plus the order ID from your receipt. Copy your Ed25519 license token (LZK1...), then in SketchUp open LizArk Render → Settings → License, paste the key, and click Activate. You can also release your key to move it to another computer.

Yes. The license key is an Ed25519-signed token verified locally against Lizatek embedded public keys without dialing home. If a key expires while offline, a 72-hour grace period allows you to continue working until you connect to refresh your key at lizatek.com/license/lizark-render.

LizArk Render runs on 64-bit Windows 10/11 with SketchUp Pro 2022–2026. For fast GPU generation, an NVIDIA GeForce RTX GPU (RTX 30, 40, or 50 series) with 8 GB+ VRAM is recommended. Free disk space of 25 GB is required for the CUDA runtime and models (12 GB for CPU profile). CPU mode is also supported for non-NVIDIA systems.

Nothing is deleted. Your projects, scene settings, and local render gallery files remain on your PC forever. New render jobs simply adhere to the Free tier limits (512×512 preview with watermark, 1 output, 1 reference) until Pro is renewed.
