UE4_Make tooltip look at and scale constraint to camera.

Cg_Creator

Hi,

If possible I would like to be pointed in the right direction to make something similar as the video I uploaded... Mostly is to have the text keep a look at constraint to the camera as I orbit around it, as well as the scale of the text being affected depending on the camera distance from it.

If you could point me in the right direction to make this sort of blueprint would be a big help.

Thank you for letting me know I updated the link should work now I hope

Look into world space widgets.

Thanks Obscura, that s a good point where to start looking, Anyone feel free to add comments about tuts or anything to get this widget to follow the camera POV, Thanks you

Great quick tut i found to get the text to face the camera, next step is have it to scale depending on the distance.

"Reminder" Cant try it just yet as I need some sleep and, if I try, i might keep going for hours. But hopefully that is something relevant.

Thanks again Obscura for showing me the way. Hopefuly I can get this working soonish.

"Reminder" You can achieve what you're looking for using a MaterialBillboard component. Add a Material Billboard to the Actor's blueprint. Then click the + to add an element to the sprite, choose a material, and click Size Is in Screen Space. You'll likely need to adjust the Base Size X and Y values to get the size you want. You can also change the Opacity and Distance to Size using a curve, if you need something more complex.

Still didnt get the scaling to work but I m getting there...

Obscura

You could try interpolating the draw size of the widget based on the distance between this actor and the player camera.

To be honest... using bleuprint... making UI... or any code base action if that makes sense. I m on noob level... been trying to avoid it for a very long time. Saying that what u are saying is exactly what i need to do... now figuring out the nodes i need and how to connect them is what i need to figure out. Feel free to give me a bit more details on how to when u get the chance. Thanks

Ok. I was at work when I was answering earlier. After I got home, I made a quick test. And the only thing you need to do is to set the widget component to be screen space, and it will automatically do what you want. This is because its added to an actor as a component. So it will always move to the actor component location in screen space. If it would be added by a node called "add to viewport", then it would be truly only screen space. Like a menu.

Thanks mate, didnt get the chance to try it yet, but I will for sure, tho still sounds a bit confusing. But I ll try my best and get back to you, if there s a tut for it feel free to share or if you can send me one or a couple images of what the bleuprint should look like or the steps would be amazing. Thanks again
