This is actually an issue I discovered later, but have not had time to correct in my video tutorials. I will try to make a new video this week, as I recently subscribed to the Pro version of Screen-Cast-O-Matic, allowing me to create longer videos.
Anyways, you will need two different burn settings, both "generic-image to data-rgt", with the following settings:
MixInputs: (,,r)(,,g)(,,b)(_dif,_alp,r)
MixInputDefaults: 255,255,255,255
CompressTextures: true
PreferredFormat: DXT1a
ForceFormat: false
RescaleNonPowerTwo: true
MipMap: true
MipDrop: 0
AlphaEdge: false
BlackBorder: false
FlipImage: true
Include:
*_dif.tga
MixInputs: (_nrm,_spc,r)(,,g)(_nrm,_gls,b)(,,r)
MixInputDefaults: 0,0,0,0
CompressTextures: true
PreferredFormat: DXT5
ForceFormat: false
RescaleNonPowerTwo: true
MipMap: true
MipDrop: 0
AlphaEdge: false
BlackBorder: false
FlipImage: true
Include:
*_nrm.tga
See if that helps. These Burn Settings expect _dif and _alp to be present, and/or _gls, _nrm, and _spc to be present. They are actually the default Burn Settings when using the wizard.
