render_highquality() fails - cannot find temprayfile.png #216

Hello! Thank you Tyler for this excellent package. I am having some trouble creating a high quality render using the render_highquality() function after passing a ggplot object to plot_gg(). Rayshader plots the ggplot as expected, and I can save a low res snapshot using render_snapshot(), however render_highquality() always fails for me when trying to render a ggplot.

This is the output after attempting to run render_highquality() with no cache file specified in the argument:

Error in render_scene_rcpp(camera_info = camera_info, scene_info = scene_info) : 
  Could not find [MY TEMPDIR]\temprayfile.png

Have tried this on two different machines to rule out an issue with my setup. Even specifying a cache file returns the same error. Would appreciate any thoughts on how to resolve.

Firts, copy and paste the output of sessionInfo() here so I can see what package versions you have. Do the files appear in the temp directory when you run the script?

Same issue for me on ubuntu with rayshader 0.24.10. It looks like tempdir() is pasted twice somewhere. When using the default function it returns something like :

Error in file(filename, "w") : cannot open the connection In addition: Warning message: In file(filename, "w") : cannot open file '/tmp/RtmpLpcKrk//tmp/RtmpLpcKrk/tmpray.obj': No such file or directory

And even when specifying cache_filename manually with something like :

render_highquality(cache_filename="/home/me/myfile")

I get the error

Error in file(filename, "w") : cannot open the connection In addition: Warning message: In file(filename, "w") : cannot open file '/tmp/RtmpLpcKrk//home/me/myfile.obj': No such file or directory

update: it looks like it works using the version on github (rayshader_0.27.4)

@simoncarrignon same error in windows, tempdir() pastes twice in rayshader 0.24.10.And follow your advice to update to rayshader_0.27.4, it works.
