I ran into this myself a few minutes ago :) The trick is that *all* pixels in the current region are need to be set to non-NULL. If NULL pixels are present, r.texture fails. run r.univar mapname to see how many NULL cells are in the current region. Solution: - either zoom into area without NULL pixels (won't always make sense) - or fill the NULL areas with some value (various options) - (or fix r.texture if possible).
