Textures breaking when in lit mode

Could someone please tell me what is happening here?

I am new to unreal and just started exploring how to do things. I’ve made a master material as the most basic level, and found that every time I go from unlit to lit, my texture breaks. I wouldn’t know where to start debugging, I thought maybe UVs, so I used Full precision UVs but nothing changed, then tried the lightmap resolution, simply because I was testing things out but nothing changed again. res was 64 and I changed to 512, no change…

the geo is from a simple lidar scan, could there be something wrong with the geo?
