--- Comment #9 from Regina Henschel <rb.hensc...@t-online.de> --- There are more problems than I first thought. The current lighting has principle errors. For details see https://gerrit.libreoffice.org/c/core/+/128449. It has lot of comments, at least in patch set #10. You can use the patch from https://gerrit.libreoffice.org/c/core/+/128449 under Apache License, Version 2.0. In case someone will work on this and has questions about the code, please drop me a mail. -- You are receiving this mail because: You are the assignee for the issue.
