12 - Viewer Background Settings - TouchDesigner Tutorial: Beginner Crash Course — Transcript

Full transcript

1. 0:00As you've been going through this last
2. 0:02section introducing you to the chop
3. 0:05family, you may have wondered why your
4. 0:08particular version of the network that
5. 0:12we built has a checkerboard background
6. 0:16like I do in this example rather than
7. 0:20the black background that you saw in the
8. 0:23previous recordings. This actually has
9. 0:26to do with a setting in TouchDesigner
10. 0:29that we have the ability to change
11. 0:32rather than there being some kind of
12. 0:34difference in the way that you've set
13. 0:35things up. By default in TouchDesigner,
14. 0:38you'll see this checkerboard pattern
15. 0:40layered behind your texture to show you
16. 0:44that there is some level of transparency
17. 0:47contained within it. So if you don't see
18. 0:50the checkerboard, you have no
19. 0:52transparency in your particular texture.
20. 0:55If you do see the checkerboard, there is
21. 0:57some level of transparency. And like I
22. 1:01mentioned before, we have the ability to
23. 1:03change this behavior if we so choose,
24. 1:06which is done via the edit preferences
25. 1:09dialog. So that is alt and P if you want
26. 1:13to use the shortcut or edit preferences.
27. 1:16On Mac, I believe you have to open up
28. 1:19the TouchDesigner drop-down in the Mac
29. 1:21menu bar at the top and choose
30. 1:23preferences from there, but either way,
31. 1:25you'll want to end up at the preferences
32. 1:28window. And then we'll head over to the
33. 1:30tops page. You'll notice here that we
34. 1:33have this viewer background setting. And
35. 1:36as we mentioned before, this is set by
36. 1:39default to checkerboard. If you set this
37. 1:41to black and then choose save, you'll
38. 1:45see that the checkerboard texture has
39. 1:48been replaced with a black backdrop.
40. 1:51Now in general, especially for beginners
41. 1:54to the program, we would recommend
42. 1:56against using this viewer background
43. 1:59mode because it's not easy to then
44. 2:01identify where transparency is located
45. 2:05within your texture. It's very easy to
46. 2:07confuse a texture that has transparency
47. 2:10with a texture that does not. And so in
48. 2:13general, we recommend for our beginner
49. 2:16users to set this viewer background to
50. 2:19checkerboard, which again is the default
51. 2:22behavior. So I hope that clears up any
52. 2:24potential questions that you may have
53. 2:26had as you were working through the
54. 2:29intro to CHOPs.
