Hi all, I tracked down the issue and will upload it to CRAN the next days (as it happens I pushed a new version and now have to wait until all checks are run by CRAN) Now texture import works. You can already update using devtools as described here: https://github.com/zarquon42b/Rvcg#installation-of-the-r-package-rvcg-latest-development-code-using-devtools
