Title: Corona Distance for density?
Post by: Lupaz on June 26, 2025, 09:34:03 pm
Hi,

I need to reduce the density of a type of plant (mondo grass) based on the distance from a path.
I thought of using corona distance as a map but it seems Forest doesn't recognize gray areas if I use it for distribution.
Is there a way to plug it in somewhere else for this purpose? If not, is there a way to reduce the density based on the distance to an object?

Thank you

I found this video to solve it.
But I'm still interested in knowing if this is possible with corona distance. thanks.

Hi,

First, let me mention that using the CoronaDistance map as a Distribution Map is possible. Just make sure that the Forest object is placed at the world origin to ensure it works correctly. To simulate varying density you can combine multiple maps. In the attached sample scene (250627_CoronaDistanceSampleScene_ITOOSOFT.max), I’ve used a simple Noise map to demonstrate this approach. I hope this helps.

Best regards,

Thank you very much for that example.
