Hi Issue 1 (default.profraw file): Yes, it is a compiler settings. The setting was set in R20 as well, the setting was probably never checked/noticed since the affected module was created. The Solidangle developer has fixed the issue in Arnold4C4D by "My workaround is to look for and remove the file from cwd in PluginStart() and change cwd to /var/tmp on PluginEnd(). This means the file is not in the folder where C4D was started from nor the project folder, only in /var/tmp which is acceptable." Which means that if I "cd /var/tmp" before starting C4D, the message should be gone. I have not yet tested it as R20 has the same issue and still renders.
