How to get an rgb value of a texture position x-y?

Hi guys! I have a light blueprint. I want to set up the color of this light in the blueprint, using the rgb values in a point of a texture.
I just can’t find any “get rgb” node.

Thanks!

Is it possible in blueprint?

I believe not. For that, your best bet would be to write it in C++ and convert it to a function library in order to use with blueprints.
