My Texture sample node isnt working

I was following the how to make grass tutorial
and i input the texture like it told me to but the texture sample node stays black it does work but when i click on the node under Material Expression Texture Base i can see the texture in it

can you show me an image of it?

Hmm… do you have the engine set for mobile? it looks like its trying to call functions from metal (mobile gpu rendering thing) which you didnt compile?

anyways, this is waay beyond my knowledge.
I’ll see if I can get someone else to look at it.

Ok, thanks though.

how would i see if it is on mobile?
