you could use free or placeholder models instead of marketplace stuff if once you decide to share the project. even simple bsp cubes would do the job.
the videos are quite long, you could divide large topics into smaller section in future (but it is really your decision), that would make their watching easier. if I know I have 15 or 30 or 60 mins free time, I could plan better to watch one or more smaller sections.
but anyway thanks for them, and I’m awaiting the new ones
