handlers("progress")
st_helens <- data.frame(
lat = 46.1914,
lng = -122.1956
)
st_helens <- st_as_sf(st_helens, coords = c("lng", "lat"))
st_helens <- st_set_crs(st_helens, 4326)
st_helens <- set_bbox_side_length(st_helens, 8000)
with_progress(
output_tiles <- get_tiles(st_helens,
services = c("elevation", "ortho"))
)
merged_tiles <- vapply(output_tiles, merge_rasters, character(1))
mapply(
function(x, y) raster_to_raw_tiles(x, "st_helens", raw = y),
merged_tiles,

This gets you a set of files in the format that Unity expects. You still need to import them by hand (for now…) – see the Unity vignette for more on that!
