I need to make a material for unit icons. This material is a symbol, and it must scale so to stay always the same size on the screen. And must also always face the camera (like a billboard).
For that, I have these 2 different WPO methods that i need to make happen at the same time, already done and working:
So again:
1- Billboard effect. Keeps the material facing the camera.
2- Keep scale. Keeps the scale of the material no matter how much you zoom in or zoom out.
They are both working well separately. They dont work when i try to combine both at the same time.
I tried Linear Interpolate, add, multiply. Nothing works. It just breaks one or the other.
Thats another method of making the material align to the camera.
Though i’m not being able to combine this one with the scale persistence either.
Here is the video:
Both methods work separately. I only need to combine them so that it faces the camera and also the scale persists.
Actually i came accross an issue just today.
If the actor that contains the symbol rotates, then the symbol also rotates.
So the symbol only stays aligned to the camera if its on a specific rotation value.
The moment the containing actor rotates a bit. It gets messed up:
The original solution that i posted in this thread, self-adapted even if your actor rotates, but it didnt let me combine it with the scale too.
This is the original solution for the rotation of the material (aligns to camera no matter how your mesh is rotated in the world) :
Now i only need to make it scale. Thats the challenge.
