Best Way To Paint Object Source Lighting? OSL Ultimate Guide

Hello! In this week's video, we are working on object source lighting utilizing a paintbrush and an airbrush. Object source lighting, or OSL, is a great way to add story and atmosphere to your miniature, but it can be a little tricky. In this video, I explore the rules of light, how to use zenithal highlighting to understand your osl, and how to apply it to your model.

How do you paint Object Source Lighting? *I uploaded this video earlier this week, but there was a glitch with youtube while uploading and my video was not reaching my audience as usual, so thank you for your patience while I figured everything out!

[@Darkvex_OG]

I paint with the same Airbrush and have noticed a lot of talented painters remove the tip when using theirs. Is this for visibility, cleaning, or something else? Love this video. Not just showing a quick paint but instead explaining the concepts is so valuable (especially for those of us who are... creatively challenged?).

[@Jdadd218]

I stopped painting models due to the pandemic because my gaming group disbanded and I lost inspiration... then I found your videos and got back into it. I Needed This video In particular i have a lot of models that can benefit from osl and I don’t have an air brush. Couldn’t be more grateful

[@Carstig]

Great tutorial, including even "basics" like the zenithal highlighting with a brush, and most important: how light works. Not the first time I saw that topic, but one forgets the details.

[@emilydowd-arrow3751]

Great video! Thank you for coming both airbrush and standard brush methods.

[@TheBattlinBarrowGaming]

Nice work, when it comes to osl there's 3 ways. The right way as presented here, the wrong way and the battlin barrow gaming way. It's like the wrong way only faster. Wish I had your skills!

[@grahamcrackergaming630]

Dang, your content is so full of info and really wonderfully laid out. Haven't found a better description of OSL. You're really good at this!

[@SpensPainting]

Great video! Really liked the theory section. Usually I just try to imagine which materials on the model would be reflective and are facing the light source, then glaze those areas

[@hecatepetrichor9563]

*Painting zenithal highlight with a brush* : whaaaaaaaaat ? As dumb as it sounds it feels very much mindblowing to me. I'm gonna try it next time ! Thanks a lot !

[@DarkMatters96]

That was a really great guide on light in general and OSL in particular! Thank you so much, Lyla!

[@abelhernandez7809]

Thank you Lyla! This video is just what I needed this morning, as I am about to paint a Marvel Ghost Rider mini.... Flaming skull, flaming motorcycle wheels... so lots of OSL!

[@SthMejin]

woot! helpful as always - though im still so scared to try OSL

[@Winterydee]

No reason to be scared of OSL. Nervous about OSL, yes. But never scared. Remember that it is just paint. As long as you're using thin, smooth coats of paint you can always repaint the model several times before you would need to strip it of paint. So if you mess it you can always repaint it and worst case you strip it and start all over. Remember that we never grow or learn if we never try.

[@PaulJones-ni2fj]

Going to use this tutorial as my guide to my first attempt at OSL🤞

[@billstubbles2398]

Stunning work.

[@ravensgategames1912]

Fantastic video Lyla! This is full of so much useful information on a topic that is intimidating for many painters (myself included!). You broke it down in such a thoughtful and precise manner that it doesn't seem so unapproachable now. Thanks for sharing!

[@NortheastPlague]

Thanks for the video, trying this on my chaos terminators. Stoked. Very informative.

[@9000ethanator]

I’m planning on painting a Reaper Fire Giant queen miniature and I was thinking of doing OSL from her hair, so I’m sure I will be revisiting this video!

[@Izzyspaintingworkshop]

Great video as always! Thanks!

[@kenholmes]

Awesome video! Very informative and helpful! 🙂

[@Hebbez]

This is a great help, since I'm practicing this today

[@billcurran7210]

This is pretty cool. I'm going to have to give this one a shot, I've mainly been using my airbrush for just zenithal priming.

[@ger5956]

Great video as always! Definitely worth watching twice 👍🏻

[@LylaMev]

Thank you kindly!

[@apeofjustice7109]

I would love to hear the story behind your cats bad track record with fire! Great video too :D

[@jamesheber7006]

I like how vibrant your painting is

[@joshgladfelter9597]

Great video! Still trying to wrap my head around OSL!

[@Walboro]

Got the Notification this time! 😎awesome.

[@LylaMev]

Great! I had a problem with the upload last time and youtube was being rude so I decided to reupload it!

[@Walboro]

@@LylaMev youtube is always rude 🤣.

[@Mad4saxBrewery]

Excellent video you are a great teacher. My OSL goes from not enough to to much in a blink of an eye! LOL

[@chucknorrissaurus4398]

As I'm getting back into mini painting. I love that all the people I'm finding as resources have cat familiars 🤣

[@thomasjones3221]

underrated video.

[@Magos_Biologis_Tyranus]

But seriously awesome video and will hopefully implement

[@Daealis]

The biggest realization for me came at the 0:20 mark. You could do a shadow of an object not in the scene! Why has this blindingly obvious notion completely eluded me before!

[@zxc1972]

"you have a very bad track record with fire" deserves its own channel

[@LylaMev]

Cardamom stepped over a candle and light his tummy on fire. He stood there like a complete dork, wafts of black smoke billowing up around him, until I realized what was going on, grabbed him and put him out. He didn't burn his skin, but he had a 3x3 inch area on his stomach of extremely short hair for several weeks, and smelled like burnt hair for days.

[@lucycannon6732]

Very informative! Here's some algorithm kibble ;)

[@nc_JP]

If anyone is watching this for the first time or coming back for a refresher here's a tip. Check out the colour torch app on your phone, it does what it sounds. Basically you can set a colour for the light on your phone. Then you can hold it up to your model as the light source and see exactly how the light interacts with it.

[@user-qk3io6jn3n]

Thanks for the video, I am planing on doing a OSL mini next so it was (heh) illuminating. It was a bit dificult following the painting because of the camera moving a lot, probably the table no being stable enough? It is the first time it happens, or at least that I noticed it

[@robertliebert-hereth8218]

Any tips if I'm trying to go for a subtler glow effect (think like glow stick in a rave) where it only partially lights a small area? or just same steps in a tighter area?

[@droghtak]

What do you think on first blocking all base colors, doing some shadows and then do the airbrush work on the OSL lights, finally do highlights etc

[@edwardp4417]

When doing osl do you usually do it before base coating, layering, highlighting, etc the rest of the model? I always thought osl was done over a base coast, highlight, etc so some of those colors were visible. I've never tried osl though so I'm just asking.

[@paintandminispaintandminis2427]

👍👍👍

[@Magos_Biologis_Tyranus]

Woooo engagement!

[@LylaMev]

My favorite kind!

[@JoeyJocco]

Very cool! Thanks especially for the tip about drybrushing the base layer of highlights. I’ll have to try that. Out of curiosity, what do you like most about domed drybrushes over flat ones? I’ve never used a domed one, but I’m thinking about pick one up.

[@LylaMev]

I find that flat brushes leave more obvious brush strokes than domed brushes

[@kurchees7723]

Hello, I know its been a while since vid was uploaded. I am kinda beginner modeller, and I am about to paint my first figure (well, there are going to be 2, but I am looking for tip for one as now), does this whole thing work with acrylic paints, not ink? I mean, those all "soft" changes of colours? Like in Paintbrush part, where yellow faded into orange/ deep gold, how can I achieve it? Hopefully someone will answer :)

[@ger5956]

Don’t forget to like and comment to appease the almighty algorithm 😁👍🏼

[@stephenspackman5573]

I don't think it's technically quite true that light is most saturated at its source. Beyond a certain point I think your eye (like a camera) overloads and starts losing colour discrimination. Reds shift to pink, for example, as the red receptors reach the limit of their range while the green and blue receptors still have more to give (even though they're not super interested in red). We're seeing it through a camera and not a human eye, but your candle appears to be giving off a reddish light, yet the flame itself looks warm white. I think the same is true with blue highlighting to aqua and then cold white.

[@psibitful2]

Good physiological explanation of color perception with respect to fire. I noticed that in both of her demos, Lyla uses saturated reds to depict fire. When thinking about paint choices, I would shift that red fire towards orange and desaturate by adding white. That would align with what we might expect from a hot flame source. Shameless plug, but I would also look into a physical color exploration and dispensing tool called TriaDart, which was developed with precision art like this in mind. Just look it up on KZbin ..

[@gkeaton9755]

Heh! "you have a very bad track record with fire!"

[@ramza813]

see folks? thats why we never let kittehs on tables

[@jrseitz21]

Just wanted to pop in and say it's refreshing to watch a woman do this kinda stuff. Say what you want and especially with the way the world is right now. but in my opinion we are not all the same lol. Women see and do and think differently than men. Everyone is not the same. Everyone has unique experiences gifts and faults. We are individuals. Point being you are going to think paint and come up with different ways of doing things then a guy...usually lol. And I don't think that's something that should be hindered mocked or made into some gender equality thing. It's always a plus. Just some people in this world only see in black and white....there's many shades of grey. Sorry if that seems ranty lol. Point is you bring a refreshing aspect to things. There's a hundred dude's on KZbin with beards and comic book tshirts all spouting the same idea's. Then there's you. While alot of the things you may do might be the same....you just have a different perspective and way of explaining what it is that you do. More women need to be like you. Also depending upon how far you take this KZbin thing don't change too much. Meaning besides some upgrades to equipment or whatever like that still be you and do what you do the way you do it. Keep the clothing styles attitude pets mistakes whatever lol. You see that alot that most people go too professional. Most people don't want that. Most people want to see what we are. Individuals with a different hobby in a carved out little nook in our own little space of mess and solitude lol. Point is don't go changing. Always follow the KISS moto....keep it simple stupid....

[@Sugar-Foot]

everything i paint looks like a sweet potato now! i got the lesson all wrong!

[@paulkenyon1830]

why do you pronounce the word miniature like that ?

[@swedboot1]

Hey. so I really like your content. But for me its a bit hard to listen to your sound setup. I think its the echo of the room any way you sound very metallic. and i would watch more. If you would have fixed it.

[@LylaMev]

This video in particular has poor sound due to loud neighbors; my sound is usually far better than this!

[@bucklalonde9529]

Great video! You touched on it a little, but is ambient occlusion something you consciously consider while painting or do you just let it happen?

[@LylaMev]

I do consciously consider it! But I always assume that there is some amount of ambient light, otherwise I think the miniature would look boring!
