3D Model shader have black areas on iPhone



we are trying to make an 3D eye (using standard lighting material) with zapworks studio. When viewed on the android, the eyeball maeterial appears fine. However when viewed on iPhone, the eyeball have solid black areas in certain part. How can we fix this? Thanks



Hi @kfkok4,

Are you launching the experience using the Zappar app or WebAR?

Would it be possible to send the model file to support@zappar.com so we can take a look?



Hi @George,

I am launching the experience using the Zappar WebAR.

We have resolved the issue by using Material instead of Standard Lighting Material and removed all directional lights. This works well for both android and iPhone.

Thanks for your help.
