iFrame shows very pixelated model

[piotrszpruta]

Description

Model in model-viewer on iOS in iFrame is rendering very pixelated even with minimumRenderScale="1". I've checked on Xiaomi Redmi Note 7 and its looking much better.

In fact you did not set minimumRenderScale because it is not an attribute, but a static property. Please follow these directions for setting static properties: https://modelviewer.dev/examples/loading/#dracoSupport

I've heard some concerning things about iOS throttling 3D severely in iframes. Any info you can give on relative performance between iframe and non would be helpful. I'm afraid when you set the render scale you may end up dropping frame rate significantly.

I did same thing right now like you showed there #1708 (comment) but its showing me an error.

After decreasing vertices to 5k from 25k and setting minimumRenderScale to 1 it still shows exactly same result. But after I move it for few seconds it sometimes loads pretty good model.

If it throws an error, then you have not set the property. You'll have to fix that first to see a difference. Also, anytime the model stops moving it will revert to full resolution, so it can help to turn off auto-rotate. It should only decrease resolution to keep the frame rate up.
