You can actually create something like two pixel image to use as gradient to save even more memory. Top pixel would be lighter green, bottom one darker green in this case. If you apply it to an image component stretched across your screen Unity will blend these colors (filtering mode needs to be set to bilinear or trilinear).

Hi there, this is very true, thanks for pointing it out!
@CyberAngel674 жыл бұрын
Two colors don't make a gradient though, as gradients have many variants of those two colors. On very small screens you might get away with a 2 pixel image for this, but not in a webgl screen.
@marshmallow_fellow4 жыл бұрын
@@CyberAngel67 I think you miss understand. you aren't using the 2 pixels as the gradient. you're generating a gradient by up scaling the image. then sampling the up scaled version
@CyberAngel674 жыл бұрын
@@marshmallow_fellow I understand, but upscaling you still only have two colors, do you not.
@marshmallow_fellow4 жыл бұрын
@@CyberAngel67 nope. Most upscale algorithms try to make a gradient between pixels to make them appear to have more information than they do. Unity by default uses nearest neighbour upscale which creates a pixel which is the average of the surrounding neighbours. If you do this with 2 pixels, 1 you will get a linear gradient between the two initial colours as it tries to add detail. This is also the reason pixel art is blurry when you first put it into unity

Hey, I have some comments: - You mention using POT textures is the most important part, but that's only true in some setups. At some point you had a warning saying that it couldn't compress the texture because it's width or height we're not a multiple of 4, so that's also an option too in some cases. - Related to that and atlases, you don't need to worry about POT or multiples of 4 if you put sprites in an atlas. You kind of mentioned that, but then at the end you added a new sprite and made it POT while you could have made it of any size and put it inside an atlas. Those 2 points are really important for artists, it's better to let Unity do the annoying work and remove that step from the artists' task. Also, this is REALLY usefull whey using sprites for UI, since you usually want sprites to stretch and stuff like that. Having extra invisible space makes it harder to place them consistently. - When you created the atlas you mentioned that since you had some big images, they took all the space and some other images didn't fit in. You don't need to remove them, when you create an atlas it'll automatically create multiple textures to fit everything. You can see these other textures if you press the "#1" button in the preview header. I'd suggest you keep everything in the atlas to save more space. - The 40MB atlas can be imported as individual images and let Unity put them in an atlas. May seem redundant, but if you compare your handmade atlas with Unity's you'll see they pack sprites a lot tighter, you might save some more space if Unity's packaging removes enough empty space to use a smaller POT size But anyway, this was a really good video, lots of people don't know about this stuff and it's nice to see real world examples of the benefits of using good import settings.

Having extra invisible space makes it harder to place them consistently. I don;t understand what you mean here. Sprites can be tiled and 9-sliced all the same regardless of whether they're in an atlas or alone or NPOT texture
@vivienlynn25853 жыл бұрын
@12:20 this is a nice tip! You can go even more crazy and have the sprite only consist of 2 pixels (1 wide, 2 high). Unity will then create a gradient for you. I think that leaves you with a file size of 8 Byte ;)

Hey! I'm wondering if there is some way of optimizing the "Imported DLLs" part, I can never get it below 13 MB, I'm fairly sure that it's the actual engine code, but even removing internal packages such as AI or Video doesn't change this value at all. Do you happen to know how to reduce this value even further? Are there also tips on how to optimize RAM usage?
@GameDevLuuk3 жыл бұрын
Hi Rafael, thanks for your questions. Optimizing is a very broad topic with lots of different and specific tricks for each game. From the top of my head an empty Unity project is about 6MB in total. My guess would be is that you are using certain packages. RAM usage would be your textures, models, sprites you use. You can check de Frame Debugger to get a step by step overview of exactly what is being sent to the RAM and how costly it is. Consider static batching, dynamic batching, light baking, texture atlases. Luuk

The change to the power of 2 seems to have a reverse effect in my project. While I had to reduce the width of my sprites slightly I also had to increase the height (added transparency) on most of them and after the changes the project is slightly bigger. Has anyone got any ideas about this? Not a big problem though I still reduced the size of the project significantly by: * lower the quality of sounds and music. * change compression from gzip to brotli (my new server supports it, it works well) * change texture format from DXT to ASTC * strip unused code (high)
