Is there any functionality in Unreal right now for getting a color from a gradient?
In Unity, for example, you can make a gradient and choose a random color from this gradient or add a texture and get a color from the texture based on coordinates.
I don’t see anything in Unreal Engine 4 that lets me do this, making problems like heatmaps very complicated.
For my heatmap, I ended up writing a gradient in C++ that generated RGB values.
This is a really poor and inflexible solution.
