Alpha Channels and Grass

Using Alpha Channels to create usable grass assets for unity

First i started off with an image of a fern image like this

then i opend up photoshop  and used it to remove the white background and set it to trasnparent getting a result like this. I then exported as a 512x512 image for use in unity

after importing it into unity and inputting it into the terrain script i was then able to paint grass onto my terrain.

the results are pictured above

This is incredibley useful for areas the require foliage as it is easy to get a large amount of different  plants by just using stock images and editing them for use in unity
