Spring RTS Engine

Is it a good idea to have multiple textures for very similar units on one texture?

E: As in a uvmap..

Might save download size but it'll be alot of hassle and no improvement in ingame memory use I think.

The smaller file size is negligible. For almost all cases, if you can create a 1-1 ratio between a texture and a quad on the model, do it (this basically holds for all 3DOs ever made).

I use UV maps, So I guess a 1:1 ratio between textures and units would be best

So, overall I guess I'll just make em normally, thanks for the feedback.

What leads you to this conclusion?

Surely having one 512 x 512 texture for 5 units uses less memory than one 256 x 256 texture for each of the 5.

It didn't seem very likely that spring would only load the texture once even though it was seperately referneced in multiple units.

That's the real question.

Yup ^

Don't have time to answer it right now, tho, I must sleep.

1x512x512 is less than 5x256x256, yes but it also means less UV space. I do use the same texture for similar units but that's because I use the same model, too and just hide parts depending on what the unit is.

Spring loads every texture file once, no matter how often it is used.

Using the same texture for multiple units should be slightly faster since it reduce the number of state changes (both texture1 and texture2 has to be shared by the units for this to be true).

Spring '44 leads the way.

Its only an idea...Small metalic Logos textures a la TA.
