Hmm, I thought I posted this, guess not.

Will it be possible to use a single alpha channel to control glowmaps? ie, you have your base diffuse texture, with alpha, and then you have a single additional channel that handles the glowmap 'intensity'.

Ditto for shinemaps.

Since most textures only really make use of the base 'this thing glows' and 'this thing shines', it could reduce memory usage a lot.

cant really think of anythi g off the top of my head, but im planning on taking the next 3 days off of work again, so if you need anything for testing let me know.

[Bobboau]

yeah, I'm prety sure that can be done, if it's posable to do at all then it will be posable with this system.

That's not true.  Almost all of the new maps have the glowing points removed from the base map, so that when the lights are off they go black instead of diffuse-color-of-the-light.  I actually can't think of any major examples left where this is not the case.

Speaking of wich, we needs the lights to turn off for debris.

It seems absurd to me, though, that we need four full channels just to add red glow gradiants on Shivan fighters, for example. When we start loading bumpmaps or normal maps, it'll just get even worse.

Take this for example:
Fighter with one 1024x1024 map for the entire ship:
4.1 MB Diffuse
4.1 MB Glowmap
4.1 MB Specular
4.1 MB Normalmap
----------------------
17.4 MB per ship.

For every channel removed, the size goes down by one megabyte.

^dont you mean 4?

And couldnt you have a pixel shader that creates an animated red gradient from a greyscale map (once we get those implemented ofcourse)

[Bobboau]

well the great thing is very soon it will be easy to change things like that.
I can't off the top of my head think of exactly how you would  add the multiplication of texture A with the alpha chanle of texrue A to  the multiplication of texture A and the defuse color. but there's probly a way to do it .

oh, yeah, and I just pluged a little memory leak (stupid virtual destructor crap) and added an optomiseation that will reduce any constant subexpression to a single constant. so ((3*4-1)/sin(ln(34^5)))+107^5 will be replaced by14025517295.277

I get 14025517343.315744886 with the Ubuntu calculator .

[Bobboau]

I got that from my TI89, given that the TI89 costs more your calculatore must be wrong

[WMCoolmon]

Mine has more decimal points than yours.

[Bobboau]

no it doesn't ,
no it doesn't !

I wish i had a TI89 silver.

well this is freaking cool to the point that I need to show off, this is a build and the requiered table.
this is a build that has gives glowmapped ships a pulseing glow, it' doesn't quite work in game (though it shouldn't crash, however I can't garentee it. it WILL use the wrong textures for diferent effects)
feel free to play with the table.

things are extreemly limited untill I get the model files upgraded so you can choose wich material to use.

When's it going in CVS?

[Singh]

Well, the build crashes whenever I try to look at a ship (any ship, even if its my own using the '.' key, and backgrounds dont work at all. However, it doe-

*sees all the ships in the techroom

Holy....sh...****!!

*goes to get FRAPS

[Bobboau]

if you want to play, the material glowmapped_shinemapped is the one used by most ships.
it also has a commented out texture matix example (that shows translation in one direction)

"When's it going in CVS? "
heh... gona be a while

[Singh]

.....i didn't understand the half of that...

[Bobboau]

wich half?

[Singh]

......
*looks down in shame...

Both....

btw...I do have a video showing the effect...captured it with FRAPs...anyone got place for a 15+ MB file? GW seems to be down right now :/
