What is PNG Streaming?

PNG Streaming is a feature that allows you to stream on IRIAM using a single illustration. While it doesn’t support facial expressions, the model can move within the screen using face tracking.

It’s designed to make streaming easy with just a smartphone, especially for those who don’t have a Live2D model. For those who do own a Live2D model, it also serves as an alternative streaming method—ideal for trying out different outfits or experimenting casually.

Additionally, we plan to release an updated version soon that will allow for eye and mouth movements by uploading multiple images.

Here’s a demo video that shows how a model using 4 images with PNG Streaming feature looks like:

Requirements

• PNG image with transparent background
• Maximum height: 2000 px
• Maximum width: 2000 px
• Maximum file size: 4.5 MB / each image
• Full Body Illustration
• Since the model moves around the screen, a cut may become visible if it’s an upper-body-only model.

Display position

In IRIAM’s PNG Streaming feature, the area around the blue circle in the template images is what will initially appear on the center of the screen, and you can move the model from there using face tracking or the zoom-out feature.

If the model does not appear in the intended position, try adjusting the padding of the image and upload it again.

How to adjust position of your model

With IRIAM’s PNG Streaming feature, it’s possible to stream using characters of various proportions.

For models with standard proportions, the character’s face will typically appear in an appropriate position on screen without needing any intentional adjustments. However, when using characters with very short proportions like Chibi Characters, or conversely, characters with very tall proportions, the model’s face may appear lower, higher, bigger or smaller on the screen than expected.

In such cases, you can adjust the blank space within the illustration to change the model’s display position.

Let’s look at a real example.

In the example below, when a low-proportion Chibi Character illustration was uploaded, the model appeared lower and larger on screen than the intended position.

So, using the template image as a reference, I added some blank space to the bottom of the illustration and slightly reduced the size of the character within the image before uploading it again.

Now the model appears right where I wanted it!
