fit objects to surface
ok, this question must have been risen here allready I just cant find anything - so here´s my question.
I have a wide area of soil with grass on it. the plants which are needed to be placed on the ground are lowPoly-alphaTexture models simply planes most of the time. the ground surface is uneven. so -
the tricky part - I´ve allready placed the plants from the top view. what I now need is to make them stick/fit to the surface by somehow constraining them with a script (only Y-axis matters in this case.) paying attention to the Y-axis and only and the normalDirection of the soily groundSurface.
I got about 10,000 (simple planes only) objects, so I realy need a script or something.
I allready googled alot, but theres nothing I found what is actually working how it´s supposed to do. maybe I just used wrong keywords...
reminder: I dont want to fit the objects to vertices - they just need to be moved down until touching the surfaceGeometry.
I hope anyone can help me. Script, Url, ideas - it doesn´t matter - any input is greatly appreciated!
everything starts and ends in the right place at the right time.
