Ola,
i'm facing a challenge and crunching trough it. im a python starter but i like it.
What im trying to do is to replace all the textures paths in my scene (Materials setup : color channel -> multishader with 10 videoclips in it) in all Materials in the scenefile.
Here is the catch.
im replacing the low mp4 with an image sequence with it respectful folder. the thing that changes is basepath\imageseq_name\imageseq_name_00000.jpg where for every file there is another name (namex_00000.jpg in folder namex) which replaces basepath\allstuf\namex.mp4
Hope you understand what im trying to achieve.
For now i managed to do all the above except getin trough to multishader to replace the respective paths, otherwise im creating all new materials for every mp4 which gets replaced in multishader (located in color chan).
Here is my working script, please do not bithc me out im still learnin and its very fun, hope i can manage to do some more complex things in the future.
