Falloff graph

chrbjerre

I need some help understanding the falloff graph. I can't figure out how to make for instance a grass lawn, where the grass becomes less dense as longer from the camera it gets. For example that the density is 100 % from 0-10 meters, and then reduces to 20 % at 50 meters

chrbjerre Hi, have you tried to refer to manual? It should clarify a lot - https://help.rhinonature.com/manual/field-of-view

If this won't help I'll prepare an example for you.

Hi again

Yes, I tried refering to the manual. I feel a bit stupid, but I don't understand how the fallout graph works. So I would be very pleased if you give me an example

chrbjerre Well this graph should be somewhat informative also https://help.rhinonature.com/manual/falloff-graph

Besides that here you are (didn't know which ver so made it in v5 so everyone can use it)

In general, to use FOV you need to create a Named View in Rhino so RN will be able to fetch its properties, direction etc. best bet for the beginning is to hit the small [A} button to create range bounds (it is taken from scopes objects virtual bbox size) after initial setup you fiddle around to get the desired result that's all basically.

If you need any further guidance just let me know 🙂

Thank you for helping. I used the Density Falloff under scopes. That's why I couldn't get it to work as I wanted 😊
