Normal Maps... how to add

[aGorm]

Hi guy's, how do you add normal maps to units? I can't find any info anywere (I know it's here somewhere from like years ago, but search isn't finding the right threads). Anyone able to link me to how you get it working?

(What, me, units in game, no, never... )

Check out the BA remake from google code:
http://code.google.com/p/baremake/

You will need the following from it:

Everything from :
LuaRules\Configs\UnitMaterials

LuaRules\Gadgets\gfx_customUnitShaders.lua
LuaRules\UnitRendering.lua

You also need gadgets.lua and draw.lua from LuaRules.

Add the following to the unit's fbi/lua:

Code: Select all

  [customParams]{
		normaltex=unittextures/Core_normal.tga;
		normalmaps=yes;
	}

Additional info:
Texture 2 reflectivity and specular is separated into green/blue channels, respectively.
Normal map alpha is damage texture, glow is modulated. The rules for this is defined in:
LuaRules\Configs\UnitMaterials\1_normalmapping.lua

Code: Select all

local function DrawUnit(unitID, material)
  glUniform(material.frameLoc, maximum(0,sine(modulo(unitID,10)+GetGameFrame()/(modulo(unitID,7)+6))))
  health,maxhealth=GetUnitHealth(unitID)
  glUniform(material.healthLoc, 2*maximum(0, (-2*health)/(maxhealth)+1) )--inverse of health, 0 if health is 100%-50%, goes to 1 by 0 health

Enjoy! Feel free to ask more if above explanation is insufficient!

Also, thanks jK!

[aGorm]

Many thanks (also, reflectivity and specular separated? Awesome)

[aGorm]

OK, the second I add in that custom pram line, the unit doesn't load... Have I done somthing wrong (obviosly I have, I mean, anything in the unitdef...)

Code: Select all

local unitName = "cyberlord"

local unitDef = {
name = "Cybernaut Lord",
Description = "Elite Ground Unit",
objectName = "cyberlord.s3o",
script = "cyberlord.lua",
buildPic = "placeholder.png",
--cost
buildCostMetal = 100,
buildCostEnergy = 100,
buildTime = 2,
--Health
maxDamage = 100,
idleAutoHeal = 0,

--Movement
Acceleration = 0.2,
MaxVelocity = 1.5,
BrakeRate = 0.3,
FootprintX = 1,
FootprintZ = 1,
MovementClass = "Default2x2",
TurnRate = 900,

sightDistance = 300,
Upright = 1,

Category = [[LAND]],

Builder = false,
CanAttack = true,
CanGuard = true,
CanMove = true,
CanPatrol = true,
CanStop = true,
LeaveTracks = false,
weapons = {
[1]={name  = "Tesla",
	onlyTargetCategory = [[LAND]],
	},
},

[customParams]{
	normaltex=unittextures/Core_normal.tga,
	normalmaps=yes,
  }
}

return lowerkeys({ [unitName] = unitDef })   

[knorke]

normaltex=unittextures/Core_normal.tga,

missing "" ?

[Beherith]

Indeed, you tried to add a def from a tdf file to a lua file.

Try this:

Code: Select all

  customParams           = {
    normaltex = [[unittextures/Core_normal.tga]],
   normalmaps=[[yes]],
  },

[FLOZi]

BA remake gadget a fork of ZK one or just up to date with latest changes?

S44 one probably needs updating...

(springcontent.sdz, anyone?)

(Also we should talk about lua-ing your gamedata/ files)

[aGorm]

Cool, unit now loads... can't see the normal map though... but I'm out of time this lunch so I'll have to take anothe rcrack at it tomoz.

aGorm

[Beherith]

Fork, dunno from when though. I guess about a year.

Still not working (I double checked everythign was copyd over correctly...) and the info log looks like it loads the gadget... any ideas?

[FLOZi]

Problem may be that BAR uses the CA gadgetHandler, you may have to pull all of that in.

Alternative is to try using S44 normal mapping gadget which works with base content gH.

[aGorm]

Tryed the S44 one to, but it's not playing ball... I know this PC displays the normal maps as there there in S44, but I must be missing somthing in what I've copyed. If I were to zip this up would anyone care to take a look?

aGorm

::EDIT Thanks Beherith ::

[Beherith]

You also need gadgets.lua and draw.lua from LuaRules.

[aGorm]

Bah, wood for trees... moral of teh story is... read carfully and dont delete things just because you can tell what they do.

aGorm

PS, it works and it looks great.

[aGorm]

OK, so you though the questions had stoped right? well your wrong.. I'm back with whole new problem!

error.jpg

(91.88 KiB) Downloaded 2 times

For some reason, after I converted the normal maps to dds, all the normals seem to be backwards... (See how the sunny side is the same as the side with shadows...)

I'm assumeing that it's somthing to do with dds' and normal maps, so does anyone know what settings I have to use? (I was unsing the nvidia photoshop plug in...)

aGorm

[KaiserJ]

not sure i understand 100% (looked at the pic, nice models dude btw) but what you're saying is that your normals are turning an inset area into an outset area?

i've never used photoshop normals for anything (played with the filters etc though) as i normally build normals directly from a cavity map or height map or mesh...

possible solution: convert your normals to a greyscale cavity map, invert the cavity map, then convert back to normals

also it might be a problem with your algorithm settings in photoshop, possibly just something to click

[aGorm]

No, (I did have that but i dorted that out...)

This is that (if you look carfully) the bright side of the model (IE thats lit by the sun) is also the side with the shadows. IE, the lit source is on the left, but the light is showing on the right on the models.

aGorm

[Beherith]

Post normal map pls and dds too.

[aGorm]

No problem.

For some reason the dds one looks lighter, but otherwise the same... not sure why teh conversion would do that.

aGorm

::::EDIT:::: Thuther to this... I re-re-exported them adn now they work fine... must have been some weird glitch.
