Required alt text field in assets I'm not sure if this is a bug or I'm doing this wrong. I have an asset volume called "Blog Images" and there is a custom required field called Image alt text. If I add images in assets section I'm required to put something in for the alt text, that's good because that what I intended. But I'm using a matrix block that has an asset field that looks to this volume and I am able to upload and image to this volume and not add anything in this field. What am I doing wrong? 

Also I should mention this is using Craft 3.
This is available as of 3.2. Make the alt text field required for the asset volume, then check the "related element validation" box when creating an asset field.
