create custom texture

[miarmy]

hi!

i have u and v parametr of a mesh, can i write the one pixel with them??

like 3d point tool, but with U and V parametr and python....

That UV coordinate you have is a 0-1 coordinate of an possible texture image.

If you were to put a pixel at [0.5, 0.5] on a 500x500 image, you'd be putting a pixel right at the center, at 250x250.

The mesh doesn't play a part here, once you have the UV coordinate you're in 2d-land already. The trick is usually getting the UV coordinate from 3d space, but it sounds like you've already got it, in which case you're nearly home.
