another instance of `Error in hillshade[, , 1] ...`

I'm brand new to rayshader and am simply looking to apply this to ggplot output, failing with a similar error to that mentioned in #46 . That said, I'm not trying to bring in a specific sized image, just add the rayshader magic to ggplot. I thought it was something in my actual data, but found I couldn't reproduce the mtcars example on your site, either.

library(ggplot2)
library(rayshader)
mtplot = ggplot(mtcars) +
  geom_point(aes(x = mpg, y = disp, color = cyl)) +
  scale_color_continuous(limits = c(0, 8))
plot_gg(mtplot, width = 3.5, multicore = TRUE, windowsize = c(800, 800),
        zoom = 0.85, phi = 35, theta = 30, sunangle = 225, soliddepth = -100)

Error in hillshade[, , 1] * scales::rescale(shadowmap, c(max_darken, 1)) : 
  non-conformable arrays
