Aerosoft EHAM and alpha channel

Featured Replies

Hi,Yesterday I have noticed that more than 50% of the textures in EHAM Texture folder lack alpha-channel. Most of them are DTX1 textures with 8-9 mipmaps. From my previous experience with Maddog 2006-2008 I know for sure that this is the primary reason for textures' blurriness. Here is the question - is there any way to automatically assign alpha channels to more than 50 textures?ThanksDmitriy

No, an alpha must be present in a DXT3 texture, a DXT1 texture is not required to have an alpha channel.Also alpha's do not impact on blurry textures, that will be caused by mip maps if your graphics settings are not set up properly. With proper set up mips are essential for stopping shimmering.Alpha's have to be applied by resaving one by one in DXTBMP, there is currently no way to add an alpha to a texture by batch when it has previously been stripped out.

Can you please tell us what proper setup is ?

Not strictly true. This can be done in ImageTool using the -createalpha switch. However, this can only be performed when converting to 32-bit textures (-32 switch). Should you require DXT1 textures, another batch conversion has to be performed on the newly created 32-bit textures using the -dxt1 switch.Gary

Mine are set at 3 and I have no more shimmering at all.......................John

Better to save it back as DXT3 as opposed to DXT1 w/alpha.Adding an alpha to a DXT1 w/o alpha and saving as DXT1 w/alpha will cost you 25% of your color palette.regards,Joe
