Render to texture, project image on the plane - Grass for unity- problem

Hi, Unity has this really cool feature that u can create decent-looking, gpu friendly grass just from texture, which is perfect for my needs, but frankly i have no idea how to bake it in blender.

What i’m trying to do is to project my 3d model grass with gradient texture to a plane, to get texture which has uniform lighting (only diffuse color without light or shadows), has alpha channel and is in ortographic perspective.


something like this

As i am copletely blue in this area of blender i would really appreciate any help in this matter. Peace!

Ok, somehow i did manage to achieve decent looking result, i can explain workflow if anyone is interested, but i’m not sure if i should do it here or in tutorial section.
