Blender animation progress: How I fixed the Blender audio issue I was having in Ubuntu

A look at the making of the music video I'm animating in Blender Grease Pencil and how I fixed the audio issue I was having.

Turns out it was specifically a problem in the Linux/Ubuntu version of Blender 

I've been animating a music video for my band Lorenzo's Music in Blender because I wanted to learn how to use it. 

In a previous video, I was having a super annoying problem with the sound. It kept crapping out on me.

Here's what would happen...

I would scroll through animating the mouth with the audio and the sound would disappear and the only way to get it back would be to shut down Blender and start it up again to get it back. But it would continue to happen after a few minutes. Super annoying!

I got a lot of good suggestions from people that saw the previous video I posted about it. But nothing that worked.

Then one person mentioned that I should check the sound preferences in the settings.

Nothing seemed out of the ordinary there at first glance. But after trying a few things it turned out that is exactly where the problem was.

What finally fixed it?

I think this is a Linux-specific issue with Blender because in Ubuntu by default it uses pulse audio as the default audio device. I know from experience that pulse audio can sometimes have problems playing nice with programs. 

And I had Blender set to use pulse audio because, well... that's the default sound system.

But I figured why not look and see what some of the other audio device choices are in there.

I switched it to the one called OpenAL which is an open-source audio device that was built into Blender. 

And it worked!

It's been smooth, when I do the sound scrubbing frame by frame it's actually even better than it was before. I've had no problems with it so far.

In the video, I also talk about one of my favorite things I found in Grease Pencil for 2D animation

There's something that Blender has in it that I love. Using the sculpt option to squash and stretch the drawings.

I don't even have to draw the squash and stretch parts when I'm animating. All I have to do is switch to the sculpt mode setting. Then I use the push module from the toolbar and I make the radius really big.

All I have to do is drag it over the element in the drawing and squash the drawing. Then move to another frame and pull it back into place. I love that feature!

By the way

I recently found one of the first animations I ever made on an old hard drive and recorded a video about it 🤣

New song! Variation witch

Keeping up with my plan to release new music every month.  This time around I venture into the punk blues realm. Sort of a mixture of The Black Keys and The Eels . This is a song called "Variation witch" by my band Lorenzo's Music .  The cover art is actually an antique top that I have in my collection. What I liked about it was the striped disc kind of like something in a Tim Burton film.

Can I Buy And Resell Copies Of My Own Book From Amazon KDP?

There are two questions that I get asked about publishing my webcomic books on Amazon KDP . 1 - Can I Order A Print Copy Of My Own Book From Amazon KDP? When I started printing on Amazon KDP I also had that question. The reason I put the books together is I was just kind of doing it for myself. I could make a paperback version of my webcomic books and then I and my family could get a copy. It didn't even occur to me that I could actually start selling the book in public.  I thought it was just print-on-demand and then maybe I could order one.  But when I print a book on Amazon KDP I can also get up to 999 copies and sell it on my own!  I was able to get my own copies from Amazon KDP sent to me.  As the author, I can get them at printing cost . So they're at a discounted price. The option to order author copies is right in the KDP publishing setup.  The button is next to the book in KDP. 👇 The other question I get about publishing my book on Amazon KDP... 2 - Can I Sell My A

A quick peek behind-the-scenes of a new webcomic series. Coming soon!

I've recently paused my usual diary comic to dedicate my attention to an exciting new project—a fiction webcomic series featuring two characters that may be familiar to my long-time followers.  These characters, Bobert and the Monster have made appearances on my website before , and now they're taking center stage.  I'm working diligently with the hope of launching the series shortly.  In the meantime, I'd like to share this behind-the-scenes video of the drawing process for one of the upcoming pages.  Stay tuned for more updates as I bring this creative vision to life.

Working on a new comic

Drawing tablet screenshot I've been working on a new comic book idea. These are some screenshots of a few panels of a comic I'm drawing on my tablet. It's actually based on some characters I've had for a while called Bobert and the Monster . I don't even really remember how I came up with these characters themselves but the concept is:  It's a world made of monsters and humans are the ones that haunt and terrorize them. Specifically, Bobert the human haunts and plays tricks on the main character who is just called "Monster".  When I first started drawing them years ago they were just one-page gag comic strips. I was inspired to draw these characters based on those in-between comic stories I read in those old Gold Key and Dell comics from the 60s and 70s. Those comics would feature a main character like Yogi Bear or Huckleberry Hound . Then there were random one-page stories with a different character in the book to fill it out.  I had drawn a few o
