Maya, Houdini and Cinema 4D: export to USD, FBX or Alembic and render on JANCTION GPUs

JANCTION Render runs Blender, not Arnold, Redshift, Karma or Cinema 4D's renderers, so the tools for Maya, Houdini and Cinema 4D do one thing: export the scene to a file Blender imports (USD or FBX from Maya, Alembic or USD from Houdini, FBX or USD from Cinema 4D), upload it with the textures it references, render it with Cycles on an NVIDIA RTX PRO 6000 and open the result. Geometry, animation, cameras and basic textured materials carry over; renderer-specific shaders, render passes and most lights do not, so the scene is lit with the studio HDRI preset by default. Preview (4 frames), Final (MP4) and Turntable buttons; welcome credit of up to 500 JPY (100 JPY with no card, 400 JPY more after registering a card, which is not charged) per new key, then 0.1 JPY per GPU-second (previews free up to 2 GPU-minutes a day). AI agents connect at https://render.janction.jp/mcp (remote MCP with OAuth; connecting creates a free key).

What it does Your own .blend, bpy script or 3D file (glTF/GLB, FBX, USD, OBJ...) rendered to images or video on a cloud NVIDIA GPU, from an AI app, the terminal or the browser. The first preview needs no payment.
What it does not do It does not speed up the Blender viewport on your machine, does not take non-Blender video, simulations or general GPU jobs, and an AI that is not connected cannot render on its own.

Browser only; no connector or CLI needed. A 100 JPY welcome credit for a new key (14 days, no card; one per network every 30 days, further keys on the same network share what is left), and 400 JPY more for saving a card that is not charged (once per card); after that, previews stay free up to 2 GPU-minutes a day and finals cost 0.1 JPY per GPU-second.

Code and the full install notes: integrations/ on GitHub. The tools use only the Python inside each application (standard library, nothing to pip-install) and keep the application responsive: upload, wait and download run in a background thread. The first run creates a free key and stores it in ~/.janction_render.json.

What survives the export

  • Carried over: meshes, transforms and animation over the frame range, cameras (USD and Alembic), base color with textures (UsdPreviewSurface, FBX Phong/PBR). The textures of file nodes and bitmap shaders are sent under their file names; paths inside ASCII USD are rewritten so the farm finds them.
  • Dropped: Arnold, Redshift, Karma, V-Ray, Octane and Standard/Physical shader networks, render passes and renderer settings. Lights rarely map to anything useful in Cycles, and Alembic carries none, so the studio HDRI preset lights the scene by default (sunset / overcast / night, or "scene lights only" to turn it off).
  • Not handled: texture paths inside binary USD (.usdc), UDIM tiles, image sequences, and two textures with the same file name in different folders.

Preview, final, turntable

  • Preview: 4 frames spread across the range, tiled into one sheet.png, a few GPU seconds. Look, adjust the export or the lighting, send again (identical files are not uploaded twice).
  • Final: every frame of the range at the final size (capped at 1080p worth of pixels) as an MP4; a single frame gives a PNG. Up to 3,000 frames per instruction (automatically split internally).
  • Turntable: the current frame exported alone and rendered from 0 / 90 / 180 / 270 degrees around the model (a full turn as an MP4 in final mode).

Results open in the OS viewer and are saved under ~/janction_render/<application>/. Measured times for comparable jobs are on the benchmarks page.

From any other application

Export USD, FBX, glTF, OBJ, Alembic, STL or PLY and use the command line: pip install janction-render, then janction-render render model.usd --environment studio --orbit. AI agents do the same through the MCP server (https://render.janction.jp/mcp) with scene_url or a local path.

Pricing (since 2026-10-08): Each new key gets 100 JPY of GPU time free with no card (1,000 GPU-seconds, 14 days) for previews and finals, and 400 JPY more once a card is saved on a Stripe page that charges nothing (once per card): up to 500 JPY in all. After it is used up or expires, previews are free up to 2 GPU-minutes per key per day and final renders are paid from prepaid credit at 0.1 JPY per GPU-second. Top-ups (paid) start at 100 JPY. The first top-up during the 14-day welcome period counts 1.5x, with the bonus capped at 500 JPY (100 JPY buys 150 JPY of credit). Top-ups of 2,000 JPY or more get 10 to 20% extra (not combined with the first-top-up bonus; the larger one applies). Top-up bonuses are separate from the welcome credit and the card-saving credit. Payment is on a Stripe Checkout page. One full welcome credit per network every 30 days; further keys from the same network use what is left of that network's credit. A job without enough credit gets HTTP 402 payment_required with a checkout_url. Final renders go up to 3,000 frames per instruction (automatically split internally under one job id), 1080p (1920x1080) on free time and up to 4K (3840x2160) on prepaid credit. The free preview time resets at 00:00 UTC (09:00 JST). No sign-up: connecting creates a key. Inputs and results are deleted 24 hours after last use (normally 7 days for keys that have paid 500 JPY or more in total) and never used for training.

FAQ

Can it render with Arnold, Redshift or Karma?

No. The farm runs Blender with Cycles. The export carries geometry, animation, cameras and basic textured materials; renderer-specific shaders are dropped. Use it for previews, turntables and animations where a Cycles look is fine.

Do I need Blender installed?

No. Blender runs on the JANCTION worker. You need only the export plug-in of your application (USD, FBX or Alembic).

Why is my render lit differently?

Lights rarely survive FBX, USD and Alembic exports, so the tools light the scene with the studio HDRI preset. Pick sunset, overcast or night, or turn the preset off to use whatever lights the import produced.

Where do the textures go?

They are uploaded next to the exported file under their file names and deleted with everything else 24 hours after last use (7 days, normally, for keys that have paid 500 JPY or more in total). Files render in a container with no network access (security).
