#10807: Regarding texture scaling

by SephoD on 07/01/2008 14:39

I just wanted to get your thoughts about this...

I am making an RPG world that I want to make as realistic as possible. I have a lot of textures that I have either bought or made myself in high resolution (up to 10.000 x 10.000 px). I find that I get the best resolution on textures ingame by using these big textures and scaling them down using scaletex 0.1

What I am wondering is if this does lower the fps a lot? I have applied some of these textures on large areas without noticing a big framerate drop but I just thought of asking if anyone had done this before and could let me know if this was a really bad idea...

fyi, most video cards are limited to 8192^2 pixels (and older ones, even less). also using textures above 1024^2 is just overkill, any sauer mapper can tell you that.

this may be acceptable for a few textures, but remember, the images are not compressed in memory, so using a lot of big textures become very taxing on loading times (especially the initial load), and can trigger substantial FPS drops, specially due to the huge space they occupy in memory

For future reference, 1024^2's the current sane limit

Someone recently mentioned (mitaman, I think) that he creates textures twice as large as they need to be and then scales them with texscale .5.
That's probably acceptable, but huge (10,000 px sq) isn't, really. As Hirato Kirata mentioned, it's going to eat up all the video memory.

One of the big draws of Sauer is that you get high quality on older hardware. We don't want to exclude that part of the fan base, now do we? :)

He he I get the point :)

Its still amazing how much better the textures look if you scale them down this much, have you guys tried this? I used a grass texture sized around 8000^2 and it looked amazing, almost as being outside :)

But I will try to scale this down a bit and use as few high-res textures as possible :)

Thank you for your pointers :)

P.s. The heightmap problem is still annoying me. Does anyone know where I can find the code for the heightmap... I really want to try to get it down one cubesize :)

#10811: Detail Mapping

by Osbios on 07/01/2008 16:52

You don't need such big textures. Textures with Detail Mapping would also look nice.

Basically you just scale a repetitive noise texture down and lay it over the real texture. I'm sure you can do this in Sauerbraten with shaders. I tried to do this in fixed-function mode but it didn't work. :(

#10812: I have an idea.

How many of you know about the game Portal?

Well, I need to know a few things:
One: What type of models does Cube 2 use?
Two: Wheres a good place to learn how to use the Cubescript?

If anyone would like to help me with this small little mod, please, tell me!

Unfortunately, it's very hard to do without obvious tiling

Where exactly are these "detailed instructions"? They're not on the wiki, as far as I can tell, and there not in the node, unless I totally skipped over them.

#10818: Sauerbraten

by DBV on 07/02/2008 12:19

Hello everyone :)
I am currently playing Sauerbraten on Mac OS X.
I am into it so far, but I would like a more realistic setting without Devils and other Monsters. :)
Are there any Mods wich would make Sauerbraten look different?
Excuse me if this Question ist stupid, but I am new to this subject :).

Greetings,
Nick

Im not sure I understand what you are saying...

Are you asking for more realistic monsters, or more realistic maps?

reply to this message

#10820: Re: Sauerbraten

by MovingTarget on 07/02/2008 15:16, refers to #10818

If you want more realism, go with AssaultCube, which is a Cube mod.

More realistic everything... :)
Like actual weapons instead of light-guns etc,
I checked on Blood Frontier, but was not able to Install it...

I will take a look an AssaultCube thought, thanks for your answer!

If you're looking to start a Portal Mod, check out these two maps:

That reminds me, I've made some more puzzles (flinging!) that I need to finish polishing and upload.

Try scaling up the (or using a bigger) noise texture.

OLD card !!!

you can try the latest driver
http://ati.amd.com/support/drivers/xp/radeon-prer300-xp.html but even if you get it working playable fps may be beyond you
