Bright_ texture name in CFS2 GSL SCENERY

Robert John · 1 Jun 2012

I develop for cfs2 and would like a little understanding of what I done with the asm code ,why it works, and is there a easier way. Objects in gsl scenery do not show night textures. I found a work around. The first object I do give the material the bright_name, when I save the asm, no mention of bright_ and is not bright in the game.
I then texture a object with the built in gmax white material and give the material opacity of 1. I then copy MATERIAL_DEF 0.000000,0.000000,0.000000,0.007843, 0.000000,0.000000,0.000000, 0.000000,0.000000,0.000000, 0.992157,0.992157,0.992157, 0.000000 ; 0 and past MATERIAL_DEF 0.000000,0.000000,0.000000,0.007843, 0.000000,0.000000,0.000000, 0.000000,0.000000,0.000000, 0.992157,0.992157,0.992157, 0.000000 ; 0 to the third object.

Hoping this is legible.

This is the macro for MATERIAL_DEF:

Code:

MATERIAL_DEF macro dr,dg,db,da, ar,ag,ab, sr,sg,sb, er,eg,eb, sp

      real4 dr,dg,db,da       ; diffuse

      real4 ar,ag,ab,1.0      ; ambient

      real4 sr,sg,sb,1.0      ; specular

      real4 er,eg,eb,1.0      ; emissive

      real4 sp                      ; specular power

      endm

1st four numbers are your RGBA for daytime textures. Next 3 (ar,ag,ab,) are your traditional night textures. Then 3 numbers for specular, then 3 for emissive (er,eg,eb), then a final number for specular power....

You increased the emissive numbers, so the texture shows at night. But I think you'll loose the daytime shading in CFS2.

I made some headway with this.

I made a cube for the night and a second cube for the day. The night cube was 40.1 and the day cube was 40.0... so the day object was inside the night cube.

I assigned a diffuse texture to the 'day' cube, and I assigned a lighting texture to the larger night cube ( That texture was white for the illumination, and had an alpha channel to make the rest transparent).

I exported the mess, and got an ASM file like this:

Code:

I added a new material that uses the emissive RGB values, and I used it on the larger box. Because of the alpha transparency, just the 'light' areas show at night.

I made the GSL library like this:

Code:

; =================================================================

    dd   0FFFFFFFFh		; West Bound
    dw  22 dup(0)
    dd  library_data - library_header

    dd  02C1D3FF9h
    dd  04259FA73h

    dd  04259FA73h
    dw  13 dup(0)

; =================================================================
; =================================================================

; This is the start of the BGL data... use it 'as is'

        dd  (offset library_0000_end)

; add additional LIBRARY_OBJECT_PTRs and end offsets to the list here

; =================================================================

;                               020000h is equal to 131072t and is 0.5 scaling

   BGL_LIBRARY_OBJECT    02C1D3FF9h, 04259FA73h, 04B77FAA3h, 0D3FB5C50h, 0, 20, 020000h, 0, 0, library_0000_end, 'MyCube_GSL'

       IFMSK     library_0000_object_Undamaged_model,     24h, 40h

; =================================================================

; add additional Dynamic library objects here 
; ( named as ‘library_0001_’, ‘library_0002_’, etc…

; =================================================================

This way, the actual object and the damaged object are just the *_0.asm files from gmax.

It might be possible to use a conditional branch to detect tod (time of day), and use separate objects for day and night... each with their own materials. I'll play with that later... the problem right now is that the emissive shows during the day.

Hi rhumbaflappy,
I am glad you have found some interest in this thread, What I am trying to do is make lowpoly gsl fires. I made a searchlight for gsl scenery using bright_texture, I then tried to give a texture map bright_ and could not get it to work so I edited the asm as in my thread above and it worked.

A thread at SOH.

http://www.sim-outhouse.com/sohforums/showthread.php?67657-low-poly-object-for-night-bombing

What I am looking into is to make fx_3 texture show up at night, I changed the texture to look like flames so after bombing at night the ground craters look like bright fires.

I am wondering if there is a model for the damage ground that bombs use in cfs2.that you know of or is it all the info in the fx file.

I realy do not understand all the code jargon, most of my work is trial and error.
