BatchX
BatchX is the desktop app that renders images and videos for a full catalogue. For the full guide, see the BatchX introduction.
Licence and plans
Is there a free trial of BatchX?
Yes. The trial is 30 days on every device, and no credit card is necessary. Download the app from batchx.ijewel3d.com. Refer to Licence and trial.
Is BatchX part of my iJewel platform plan?
BatchX has its own licence, separate from your platform plan. The organization plans include BatchX licences: 1 on Silver, 3 on Gold and 5 on Platinum. Paid platform plans also include the Batch Renderer tab in Playground, which renders one model at a time in the browser. Refer to Licence and trial.
Where do I buy a BatchX licence?
On the iJewel3D License Portal. The portal shows the current price. For more than one licence, or for an enterprise licence, write to sales@ijewel3d.com.
Can I move my BatchX licence to a new computer?
The licence is locked to one computer. A transfer is possible when the old computer is no longer in use. Send your request to batchx@ijewel3d.com.
Can I use my BatchX renders commercially?
Yes, without restrictions, also after the licence expires. This does not apply to a trial licence.
Computer and files
What computer do I need for BatchX?
Windows 10 or later, or macOS 13 or later on an Apple processor (M1 or later), with 16 GB of memory or more. On Windows, an Nvidia card with 8 GB of video memory is preferred. Refer to System requirements.
Does BatchX work on a Mac?
Yes, on a Mac with an Apple processor (M1 or later) and macOS 13 or later. The Mac app is not available for Intel processors.
Which 3D file formats does BatchX accept?
.3dm, .glb, .gltf, .fbx, .obj and .stl. Use .3dm: it keeps the layers. An .stl file has no layers, so the whole model gets one material.
How do I prepare my 3D files for BatchX?
Use the same layer names in every file of the batch, save .3dm files with Save small off, and keep each file below 200,000 triangles. Refer to Prepare 3D models for BatchX and the 3D Models questions.
Scene settings and renders
Where do the scene settings come from?
From a .vjson file that you export from Playground. Make the environment maps, the material variations and the camera views in Playground, then export the file from the Export tab. Each batch folder must have exactly one .vjson file. Refer to Prepare scene settings.
How many images does BatchX make?
One image for each selected camera view and each combination of the selected materials. For example, 6 views and 3 metals make 18 images for each 3D file. Refer to Generate images and videos.
Which image sizes and formats can I export?
Images up to 4096 × 4096 pixels as PNG, JPEG or WebP. Videos as MP4, up to 20 seconds and 60 frames per second. BatchX has no DPI setting: a 2000 pixel image prints at approximately 17 cm at 300 DPI. Refer to Generate images and videos.
My BatchX renders look different from Playground. Why?
The .vjson file or BatchX is from an older version, a layer has no material configuration, or the layer names in the 3D file and the scene settings are different. Install the latest BatchX and export the .vjson again. Refer to Prepare scene settings.
Why does BatchX hang when I render many models?
A batch of more than about 25 models can use all the memory of the computer. Divide the models into folders of about 25, with the same .vjson file in each folder. Refer to BatchX stops on large batches.
