How to enable thicker outlines in Blender

With any software demo (or with failing eyesight as we get older), it’s important to have some visual aides so that your audience knows what you’re talking about. I’ve been streaming some Blender sessions recently, and I usually have my excellent little cursor highlighter tool called PointerFocus active. That’s good for viewers to follow the cursor.

By fluke something nice that’s build right into Blender, and that’s the ability to make outlines of selected objects show up a little bolder. They call it Thick Outlines, and this is what it looks like.

I think it looks quite nice, and I’m sure I’ll forget where and how to set that up so I thought I’ll write a note to my future self (and you, dear reader) in the process. We enable this by heading over Edit – Preferences, then under Interface, there’s a drop-down named Line Width. Set it to thick to get this effect.

There are a number of other good options here to that all improve the readability of Blender on your system. Enjoy fiddling!

How to “transcode” FLV into MP4 files with OBS

By default, OBS Studio likes to record files in FLV – for a reason that’s absolutely beyond me. I easily forget to change this setting into something more sensible, which means I frequently end up with FLV files that contain my material. At that point I have no way to edit those properly.

This means I’ll have to transcode my files in order to make them useful.

Or do I? Well, yes and no. Let me explain a bit more about this dilemma.

Creating a round cutout mask for OBS Studio

I like the way my PlayStation 4 adds a soft round cutout mask to the PlayStation Camera Feed when streaming gameplay. I wondered how I could best recreate this effect in OBS Studio for a consistent experience, no matter which device I decide to stream from.

Here’s how I did it, with a little help from Photoshop – feel free to use the resulting asset without any need for further fiddling.

How to add Subscription Alerts to your stream in OBS Studio

Have you seen those fancy graphic overlays that animate over gaming live streams? They’re great for audience interactions, and when I did my research on how to create those, I came across Streamlabs.com. That’s a service most successful streamers seem to use these days.

There are two ways to set this up: either download a modified version of OBS Studio from the Streamlabs website (it’s called Streamlabs OBS, but it’s Windows only at the time of writing), or use their Alert Box widget with the regular version of OBS Studio.

I’ll show you how to get the latter option going in this article.

Getting the Alert Box URL

The way this service is provided is via a transparent graphic created in CSS, using a simple browser window. We’ll capture the output of that URL and use it as a caption overlay in our OBS scene.

To get the URL for either a YouTube or Twitch account, head over to streamlabs.com and login with either of those credentials. Essentially, you’ll grant Streamlabs access to your account so that new subscribers and donations can be accessed by their servers. On this occasion, connect your Patreon and PayPal accounts so that such notifications can also be displayed.

On the left hand side, under Widgets, you’ll find several options, among those is the Alert Box. Select it and see all the configurable options on the right. Copy your unique URL from the field that’s hidden by default. We’ll need to add that to OBS in a moment.

Create an overlay in OBS Studio

Open OBS Studio and add a Browser Source to your Scene. Note that this needs to be at the top of your list so that these alerts can be displayed on top of your scene. Mine only contains a simple Display Capture otherwise.

In the Browser properties, paste the URL from Streamlabs in the dedicated URL field. That’s all you need. Make sure to scale and position your Alert Box to your liking.

Testing Alerts

Back on the Streamlabs website, in the Alert Options, you’ll see a list of test buttons that let us trigger dummy alerts. They’ll allow us to preview how those alerts will come up when we’re live. Click any of them, then head back to your OBS preview window and see what it looks like in action.

Note that Streamlabs OBS has this option built in as a plugin by default. The above setup is only necessary for the regular version of OBS Studio, available from obsproject.com. Here’s an example of what the alert looks like:
