Hey

Well some of you may know about HL alphamapping, specially on trees.

Right now im trying to make a tree to go into hl, i've used masked alphamapping, but when i try to set the last colour in photoshop to black (because thats what i want to alphamap out), and save, re-open, it turns back to white, can anybody please help me?

well as i do remember you only need to use the basic way of doing alpha maps... skin + black and white skin of it. may if you got the wrong seeting or else ask gir or somebody advanced in 3dsm ...

then compile it ._."

you tried that?

try it with 0 0 255 (pure blue) instead of black. Also dont forget to set the transparent flag for that uvmap.

HL has like nothing to do with 3dsm, the alphamapping methods work differntly. In HL you can have..

1. addictive: which alphas out every black thing it sees, i think you can only use it for like auras and stuff like that with black and white colours

2. masked: which alphas out the last colour in the pallete of the 8 bit bmp file

HL does not have separate alphamapped files, they are in the original textures themselves but as separate colours.

i am using the 2nd method and i can not set the colour to black in photoshop, this has nothing to do with compiling, its to do with photohop, i'll try do what dj ready said

edit: still doesnt work

if anybody can help can you make it so this texture is suitable for masked? thanks

btw save it as 256 8 bit bitmap and host it somehwere else, imageshack turns it into png

only 32 bit textures can use an alpha channel.

technical:

24bit texture = 8bit red, 8bit green, 8bit blue.
+8bit grayscale or alpha = 32bit texture.

i believe only .tga and .png can handle 32bit alpha textures.

im not sure how the shaders work in half life to be honest, im more proficient with quake 3 shaders =/

well i mite have said it wrong, like, you only get 256 colours in a normal HL texture, and you can set the pallete in photoshop, HL takes the last colour in the palete of this 256 texture and alphas it out, im a lil confused
