Hi everyone,
I’m trying to create a simple level with one object, 3 lights and 1 camera that turn around the object.
I already create a BP Character for the camera and a Widget Blueprint for the HUD.
I based my script on the UE4 tutorial for HUD (UMG UI Designer Quick Start Guide | Unreal Engine Documentation), so my folder is organized like this:
Content
->MyLevel
->Assets (one asset)
->Materials (one material)
->BluePrint (HUD)
->BPCamera (CameraCharacter)
->Textures (four textures)
To begin with the HUD BP, I’ve got 2 vertical box, one contains sliders and the other, 2 checkbox. And I’ve got a horizontal box with 1 checkbox. The event graph is simple, it’s just to make the HUD visible.
Then, my BP for the camera is pretty simple too. I’ve got a camera attach to a spring arm so that we turn around his pivot and not the one from the camera and my script got two functions:
• rotate using the camera, if the left click is pressed
• zoom in or out
For now, I’ve got a bool for the two lights Fill and Rim (don’t want to turn off all the lights), and 3 float for the R V B sliders to change the color of the material. I manage to bind the two checkbox Rim and Fill in my BP HUD to the bool and I can’t manage to create a condition that will make turn off the visibility of the light, I want.
I’m more a 3d artist than a programmer, but I’ve been trying ll day to get it work but I can’t manage to found how to do it, can someone please help me, it’s very frustrating to block here.
Thank you
