|  | Juhu Transparente Textures - its me been successful 
TGAs can a 4 layer (transparentslayer) imply - XProfan can but from this TGAs no Textures produce which too yet transparent are.
For which?
walls with holes? One ball with rauer surface? Highmap via Bitmap?
or: 2D-Sprites by OGL?
light and Partikeleffekte?
now building I yet one two tools to that Save this TGAs - and then can also eachone what with begin.  |

I have now with different Programs one TGA created.
it comes always The Fehlermledung "Falsches Format".
What is it with you for a TGA and welchem Program have you got it created ?
Thank you.

it must itself circa a unkomprimierte rgba-TGA-File deal -
can z.B. with IrfanView Save. |
