| Mar 19, 2021 at 22:09 | comment | added | Rich Sedman | Alright, so '//' and '///' have subtly different meanings... On Windows, '//' prefixes with the local path using the O/S file path delimiter (eg,'c:\users\rsedman\Desktop\' - ie, backslashes) and '///' does the same but forcing '/' as the path separator (eg, 'c:/users/rsedman/Desktop/...') | |
| Mar 19, 2021 at 22:00 | comment | added | Rich Sedman | I've just re-tested this and I found I had to use '///' (instead of just '//') as a prefix or it didn't work!! Also, you're right - it's the Blender node that's doing the filename conversion on the string; I always thought it was the OSL side that was doing this.... this does mean that all strings are being interpreted this way! | |

I can just make the file path a parameter on the shader. This way, it's handled by some other part of Blender. | |

| Mar 19, 2021 at 19:54 | comment | added | Rich Sedman | You can prefix the filename with ‘//‘ to indicate the directory of the current .blend file. Does that not work for your case? | |
