Really cool for a first UE experience! I'd love to hear about how you made the screen on that handheld device! looked really cool!

@tenthousandfireants Thank you!

For the screen on the 3D model, I assigned a separate material and texture in Blender. Make sure to UV unwrap the screen so it takes up the full UV coordinate space, otherwise the widget won't display correctly on the mesh.

Once imported in Unreal it should have created a separate material dedicated to the screen, open it and create a parameter texture assigned to the base color.

Then I added a Widget component on my tool blueprint, selected it, set the Widget source as the one I wanted to render, set the render size as my desired widget size, and toggled off Render on Main Pass so the component doesn't render in the game world but only on it's render target.

Then on the blueprint Begin Play, create a dynamic material instance of the screen material and store a reference as bp variable, and then on Tick get the render target texture from the Widget component and assign it to the material instance parameter texture you created earlier using the Set Texture Parameter node.

I learned this by following the YouTube tutorial: https://youtu.be/37UmUAdIHss?is=7ZJB3FKIzZA2lySW It also explains how to size your widget accordingly And https://youtu.be/mev1kb3d_Wo?is=jPpg1K39veQOZ0a_ Wich made me discover the "render on main pass toggle"

I still haven't had the nerve to try UE :D Too bad there isn't a playable scene—it could have made for a great demo
