Document vtex #18
Description
VTex doesn't have a lot of documentation and it leads to some confusion about how it works. Paint points include:
- Cubemap creation. Needs 4 wide 3 high grid of images, aligned in a T-shape like this:
| Image | Position (x,y) |
|---|---|
| Right | 3,2 |
| Left | 1,1 |
| Back | 2,1 |
| Front | 0,1 |
| Up | 3,0 |
| Down | 3,2 |
- Supported keys in vtex configuration files:
skybox,skyboxcropped,cubemap,startframe,endframe,volumetexture,bumpscale,pointsample,trilinear,clamps,clampu,border,anisotropic,dxt5,nocompress,normal,normalga,invertgreen,ssbump,nomip,allmips,mostmips,nonice,nolod,procedural,alphatest,alphatest_threshhold,alphatest_hifreq_threshhold,rendertarget,numchannels,singlecopy,oneovermiplevelinalpha,premultalphabymiplevelfraction,premultalphabymiplevelfraction_maxalphamiplevel,premultalphabymiplevelfraction_minalphaperpixel,premultcolorbyoneovermiplevel,normaltodudv,compute2dgradient,stripalphachannel,stripcolorchannel,normalalphatodudvluminance,dudv,reduce,reducex,reducey,maxwidth,maxheight,alphatodistance,distancespread,pfmscale,pfm,psd,displacementwrinkle,specvar,manualmip,mipblend,srgb,secondary_target_pathsubs,secondary_target_reduce - General vtex usage needs to be documented too, not many people seem to use the tool because VTFEdit exists.
