anyone here…im haveing a dead line for this project so ill appretiate if someone helps me fast :slight_smile:

just a quick question is the UseAlpha button turned on… :confused:

if this button is on, then is this problem only with this particular image or with all the images which have alpha channel?

5

the draw with alpha is on…and what happens is it draws the image with alpha in the uv maooing window but on render it draws it white :S

6

this isnt it…

if you want to use images alpha channel, you have to turn on UseAlpha button under Texture menu

  1. after you have uv maped your image

2,3,4. you have to assign it as a texture to your material, to see the image

  1. then you turn on the UseAlpha

  2. you can turn on the Alpha button too to see the alpha channel

  3. then you choose your texture under materials menu and turn on the UV button menu – under Map Input

  4. and there you have it

:slight_smile:
