How do I create and publish a turntable for my 3D model?

A turntable is a sequence of renderings that plays in the Preview Window. Turntables give customers a complete view of your 3D model so they can make intelligent purchasing decisions.
A turntable must have 24-72 images. 36 images is recommended. To publish for CheckMate 36 - 72 images are required.
Regarding image resolution, we recommend 1200x1200 for turntable images. This resolution gives the customer sufficient detail while still being low enough to load quickly. In any case, all turntable images must be the same resolution.
Turntable image filenames must be sequentially numbered starting with 0 or 1.
We recommend that you create at least one rendered turntable sequence for each 3D model you publish.
These videos show you how to create and upload turntables.

Setting Up for Rendering
In your 3D software, set up a camera to look at the model. One way to do this is to put your model at the origin (0,0,0) and make a camera that targets the origin.
Set up an animation with one more frame than the total you want. For example, you'd set up a 37-frame animation if you ultimately want to have 36 frames in your turntable (frames 0-36 or 1-37). The camera can circle the model, or the model itself can rotate. The first and last keys should match exactly. For all keys, set the key interpolation type to Linear (no Ease In/Out) to ensure the animation covers a consistent number of degrees on each frame.
Note that you will render one less than the total number of frames. For example, if the first and last keys of the 37-frame sequence match exactly, then rendering frames 0-36 or 1-37 will produce a seamless looping sequence. If in doubt, set up your software to play only 36 of the 37 frames, and watch the animation to make sure it loops seamlessly. A visible "hitch" (slowdown or speed-up) where the loop starts or ends means your first and last keys don't match exactly, or your key interpolation is not linear.
You might want to put a soft shadow under your model in the turntable images, but we recommend against putting in a reflective floor. For the cleanest, most professional results, use a white background and render turntable images at 1200x1200.
Render frames to sequentially numbered files, using one of these acceptable numbering conventions for turntable images. Examples:
The number can include padding up to 4 digits. Numbers must start with 0 or 1 and continue sequentially. Acceptable file formats are jpg, png, bmp, and gif.
Under Step 2 in the Publisher, click Upload Turntable. Choose all the images that make up the turntable. Once your turntable is uploaded and the product is published, the turntable appears as a thumbnail with a 360 icon at its upper left corner.
The Publisher automatically detects whether the turntable images are over 600x600, and if so, the Image Viewer icon appears on the preview image.
If you get an error message when uploading the turntable images, check to make sure you have 36 correctly-named files that are sequentially numbered and are all the same resolution. If you continue to have difficulty, contact Support.
If your turntable halts or jerks when going from the last frame to the first, be sure to set your animation keys to have linear interpolation. See your software's Help for exact steps on doing this.
