hello i need some help with the alpha option … i have a picture of a tree and i want to put it on the scene but its got this white back ground and i know it can disappear with the alpha option but i dont know how?? can somebody help thnxz 
I think if you hit the button the says “use alpha” next to the image in the texture panel,
then you might need to set some settings in the map to with the alpha option, just keep an eye on the preview and you should be able to get it working.
thnkz i’ll see if i get it
