3D Rendering offset - Heights vs Poligons and Colors [¿BUG?]

[ssilveram]

Describe the bug Hi!

I'm trying to make a 3D render of a population map. When I plot using ggplot, I obtain the map on the right side of the following image, but when I try to create a 3D render of it, the results are as you can see on the left side of the image.

As you can see, in the 3D render, the heights are dissaligned with the colors. Really I don't know why it's happening, but I think maybe is a bug or incompatibility with my machine. Anyone can help me?

Thanks a lot!

You can find the code below

Reproducible Example The code to load data, plot and the 3D render:

#My code:

library(sf)
library(tidyverse)

library(rayshader)
library(rayrender)

Shape_Manzanas <- st_read("https://www.silvera.com.co/portal/santiago/other_files/Shape_BOG_Manzanas_v1.gpkg")

Ploteo <- Shape_Manzanas %>%
  ggplot(
  ) +
  geom_sf(
    aes(
      fill = PERSONAS_MNZ,
    ),
    color = NA,
  ) +
  scale_fill_viridis() +
  theme(

    axis.ticks = element_blank(),
    panel.background = element_blank(),
    panel.grid = element_blank(),
  ) +
  labs(x = NULL,
       y = NULL,
       borders = NULL,)
Ploteo

rgl::close3d()
plot_gg(
  ggobj = Ploteo,
  multicore = TRUE,
  windowsize = c(1366,768),
  offset_edges = FALSE,
)

Thanks for your help.

I am expericing the same issue, also while tryting to plot 3D from 2D ggplot

Finally, it was solved with the last update of the library. Now, I don't have this issue and the 3D Plot looks pretty nice. =)

I installed the packages from github repo, but still got this problem... Hier is my code:

library(sf)             # Load the sf package, simple feature,to load geometries
library(ggplot2)       # Load ggplot2 render the graphic
library(rayshader)


# Load data
cities_gjson <- st_read("dichte_2021_poly_g50.geojson")  #data for all cities larger than 50000 EW

# Preprocessing, covert value to numeric
cities_gjson$value<-as.numeric(cities_gjson$value)

# reproject to WGS84
cities_gjson <- st_transform(cities_gjson, crs = 4326)

# customerize map color
gradianColor <- grDevices::colorRampPalette(c("#fef0d9","#fdcc8a", "#fc8d59", "#d7301f"), bias=2)(256)

# Draw the plot
cities = ggplot() +
  geom_sf(data = cities_gjson, aes(fill = value), color = NA)+
  scale_fill_gradientn(limits=range(cities_gjson$value), colours = gradianColor, name = "Siedlungsdichte (%)")

# 3D Plot
plot_gg(ggobj = cities,        
        multicore = TRUE,
        scale = 150,
        sunangle = 135,
        width = 5)

ok, it works well without the colorbar legend
