im trying to create plants. i have some premade plants and tried to use them as an example and try to duplicate the effect of transparency between leaves and such. but with no sucess i read in the manual and searched for it. i figured out that i needed to somehow create an alpha channel in the paint program and import the image as a skin for transparency. i use microsoft paint and paint.net is there any way to do this with these programs and how? if not then is there a free program i can download that will do it? i dont want to pay $500 for photoshop. or is there some other technique to achieve what im trying to do? any help would be appriciated.
