here is an old trick that many people use and it helps reduce load for visitors
depending on how nice a quality you need your textures, placing several on one image can be a handy trick. it helps you keep your inventory under control (i am really bad at keeping textures organised both in-world and in the real world!) and can reduce the load for your users
in Second Life, placing multiple textures on one image is also a way to save a little money with uploads. here’s some trivia about how much those $10 Linden uploads actually affects Linden Lab’s bottom line. back when i was big into SL (well, my avatar is like 5′ 2″ with boots on), Linden Lab published all kings of user data – from user hours to revenues they earned. in early 2008, Linden Lab was bringing in $90,000 USD per month on all the $10 L upload fees! what was chump change to you and me was several people’s salaries at the Lab! o_O
anyway . . . this example is a 512 pixel square image saved as a PNG-8 with transparency and the filesize is 89 kb – that’s not too bad considering i am using it for 6 different graffiti tags in Hax Nuit
i made these tags as gray scale so that i could colour them differently for some variety and thus use each several times. it is hard to see but “is this real” and “i am rezzed therefore i am” have a linear gradient applied. the OpenSim people/hippo logo also has radial gradients. the ideal was to give them a bit more texture. i should have been more extreme in the gray scale gradients but what do expect from an Ener?
after importing the texture, i set it up on a phantom prim, set all the other sides to 100 transparent and then adjust the repeats and offset to show one of the textures. then i shift duplicate it and only need to adjust the offsets for similar sized parts of the texture (the top four were all the same repeats, the bottom two were different)
once i am happy with the repeats, i then duplicated them and coloured the front faces. then i name each and take a copy into inventory for archiving. i then shift duplicate the ones in-world and spend a few minutes randomly placing them and that’s all there is to it =)
