Optimizing running speed of my scenes

silverglade1

Hi, I know a few things about optimizing my scenes, I just had a few more questions.

The things I know to optimize scenes are

1- make sure your wav files are converted to ogg format. 2- lower size of your skins 3- don't use a lot of grass; or zero grass even 4- change the shaders or whatever in the inspector window of your prefab object to "mobile bumped" instead of legacy. (this helped me a lot).

My question is, how do you reduce the file size of your texture/skins? Do you open it in photoshop and click "save as" and then put the slider to zero quality? Or what if it is not a jpg file? or a png file? Reducing the size .

also, is there a way to reduce the size of the LOD objects like placeable scene objects such as buildings or trees? These don't seem to have any changeable settings. Just a colored bar in the inspector window. Are sky textures worth reducing in size?

One more. Do you need to do asset bundles if you are not hosting your game online? it sped up my game online a lot, but I don't know if I have to do them anymore, I am just doing a pc game now, not WebGl. With Ork this time.

As for the wave files, I am just going to look for a free online solution, or a free downloadable app.

thank you. any help greatly appreciated.

this looks promising, will post the results.

wow! what a great site! just converted three wav files to ogg in a row. and they sound great.

EDIT: ok maybe not so great. it makes messed up ogg files. you have to open each ogg file into Audacity sound editor software, and export it out as an ogg file again. then you can import it into unity. otherwise, from the media.io site, when importing into unity you will get this error:

unspecified error importing audiofile...blah blah.

For the texture sizes, no you don't need to do that in an external editor. Change the texture type to advanced in the Inspector, check on generate mip maps (useful for most cases), and then under the default area, change the max size and compression format to something more reasonable. If you don't know what format you need or want, automatic does a fine job of picking one for you. Max size you just need to fiddle with and see at what point you lose too much image fidelity.

For "LOD objects", do you mean actually compressing or changing the underlying model? Or making new LOD variations for each model? There is a Mesh Compression setting on the model's base inspector, and an optimize mesh check, but if you're looking to do anything drastic you'll need to import the model into a 3d modeling package of your choice, like Maya or Blender.

wow thanks for that. copied it into my notes
