need help with specular map

[rockdude86]

so im trying to add a specular map to a wall texture ive made and when running in ldr it looks ok but when i use hdr everything turns completely shiny and my texture becomes plastic!

here are some screenshots:

with hdr:

without hdr:

as you can see the ldr version's specularity is barely visible so why does it turn into plastic in hdr mode? some help would be greatly apreciated

that's what HDR does. it overbrights regions that are light intense. atm you are looking in a dark region and every tiny lightspot will be very bright due to the simulation of a human eye. if you want to bypass this effect even while being in HDR mode, you can define a region in your VMT file to lower the envmap intensity when in DX9 HDR mode. i don't have the code right in front of me but there exist several files in source engine games that use these commands.

i hope this helped

dont really know what kind of method your refering to but im already using the commands to lower the contrast and saturation.

here is my vmt file:

"LightmappedGeneric"

{

"$basetexture" "set01/brick01"

"$bumpmap" "set01/brick01_normal"

"$envmaptint" "[ 0.3 0.3 0.3 ]"

"$normalmapalphaenvmapmask" 1

"$envmapcontrast" 0.2

"$envmapsaturation" 0.2

"$envmap" "env_cubemap"

"$surfaceprop" "brick"

"%keywords" "set01"

}

dont know if it could be of any help but im not really sure if the hdr effect is the problem.

HDR is the problem. you have to insert a special { } tag (which i dont know right now since it is cryptic and long) to detect HDR mode in the VMT and use a stronger "$envmaptint" command

[rockdude86]

thanks for the help ill try to find the tag. i can probably find it on the valve developer wiki and ill try using a stronger envmaptint.

      "LightmappedGeneric_DX9_hdr"

      {

      "$envmaptint" "[x x x]"

      }

This goes inside the LightmappedGeneric bracket.

hmm i cant get that to work all i get when i replace the LightmappedGeneric tag with LightmappedGeneric_DX9_hdr is wireframe

you don't replace it, you put the dx9_hdr tag INSIDE it.
