Writing shaders for UE4; where do I start?

Thanks to both!

It’s as simple as:

• Send a thousands of positions in space (collapsed quads for billboards). It’s all sent at once.
• Vertex shader modifies them to look at the camera given a size.
• Pixel shader draws something on them

I can’t create vertex shaders on custom nodes or the material editor, right?

Just that
Thanks!

You can try instanced static mesh. It’s not as performant(at vertex shader utilization) but given that you have only thousands of them there is no performance problem even for mobile. It’s fillrate limited anyways.
