        <p style="margin-top:0px; margin-bottom:9px; font-family:'Helvetica Neue',Helvetica,Arial,sans-serif; font-size:12px"> The shaders are already precompiled after you packaged and launch the project onto your device. Be sure you have set up your project correctly for your metallic materials to render as expected. One way to make sure you are using the correct shader model is to use the 'Feature Level Switch' node within your Material Graph.</p> 
        <p style="margin-top:0px; margin-bottom:9px; font-family:'Helvetica Neue',Helvetica,Arial,sans-serif; font-size:12px"> I just tested this on an iPad Air we have here and the project loaded up fine without the need to compile shaders for the Metal material I had applied to objects in my scene.</p>

I can close the app completely and then reopen it and it doesn't occur again. The draw count goes from ~100 to over 300 and triangle count goes from 26000 to 62000. It's like something hasn't been allocated or initialized until it comes into view that first time but I don't know how to narrow it down or fix it even if I did narrow it down.</p>

Be sure you have set up your project correctly for your metallic materials to render as expected. One way to make sure you are using the correct shader model is to use the 'Feature Level Switch' node within your Material Graph.</p>

I can close the app completely and then reopen it and it doesn't occur again. The draw count goes from ~100 to over 300 and triangle count goes from 26000 to 62000. It's like something hasn't been allocated or initialized until it comes into view that first time but I don't know how to narrow it down or fix it even if I did narrow it down.</p>
