In the meantime, you'll have to work around the 3-sources limit to add this kind of lightning in your current project or study the extension itself to make it versatile.įinally, I don't think a video would be useful. It's still somewhere in the back of my mind, but I never got the required time to do it. I had plan to write my own version of this extension, allowing the user to add more sources. However, it does have a limit : It can only handle 3 light sources. There is no need to read the whole thing, just focus on Matriax's effect and you're good to go as far as Construct 2 goes, it remains the best option so far, even to these days, as it seems. Now to properly answer you, this tutorial is getting old, I plan to rewrite it with waaaay less fluff. Hello Borixsticks, sorry for replying this late, I hope you managed to keep going since then. So, it takes time and it implies that you have some artistic skills. The normal map generation is based on your several shadow drawings. Indeed, Sprite lamp’s quality has a cost : you have to draw the shadows of your sprite(s) according to the various possible positions of your light…yourself. If you want to be fast, you will be heavily disappointed. I got some of my best results with this tool. Snake Hill Game’s baby, it will cost you 30$ or 84$ to make really convincing and effective normal maps. Without any surprise, the best of them are not free. I will only cover those which are – in my own opinion – the more effective ones. I tested a large number of them this last semester. There are a bunch of tools which can generate normal maps from a basic picture, really, there are tons of these tools. I assume that the great majority will prefer to get their precious normal maps as fast as possible to continue their game project with awesome dynamic light effects. You can find much better stuff here, there and here.īut this is for the most curious of you. In this case, you seriously need to understand how they work, and it’s not with my previous explanations that you will manage to do that. First of all, you can create them yourself if you want to. Other programs just let you convert greyscale images, or require you to draw each sprite shaded from 5 different angles of light.įor the last ones I drew I downloaded the normal map sphere off wikipedia and have been using the dropper to color in my normal map in matter the alternative that you will choose in this tutorial, you will need to generate one or several normal maps. Gimp lets you make normal maps from greyscale but unity already has that built in. Sprite D Lite seems to make really good normal maps automatically and lets you adjust them after. Krita is also very fleshed out but seems to require a pen and tablet, the tilt of the pen determines the normal that you paint. It lets you select a normal off a sphere and paint it onto the sprite, or bevel, heightmap, etc. To enumerate what Ive seen: Sprite Illuminator is straightforward and good, but also 55 bucks. The methods Ive seen all have their distinct flaws so I was wondering what most people ended up doing, or if I am mistaken about any of these options. I've been going through some tutorials lately to get nicely lit pixel art in unity using normal maps, and I cant seem to find a way to do it with free or open source software.
