Question by devstudents · Aug 06, 2015 at 01:47 AM · textureterrainvector3runtime

Change texture on terrain based on Vector3 at runtime

I want a way to change the texture of my terrain at specific positions during runtime. For example, if a rock is randomly generated at 23,0,34 at the start of the game, I want a 1x1 dirt patch texture to appear under the rock. I just need the code that would help me convert vector3 positions to whatever positions the terrain uses so I can tell the terrain what and where to paint when I generate my level.

I found this post: https://alastaira.wordpress.com/2013/11/14/procedural-terrain-splatmapping/ which seems to be about changing textures based on the height of the terrain. Since I have a totally flat terrain, it doesn't seem relevant to my project. I'm using Unity 5 and writing in c#.

Any advice?

There is doc that explains how to convert the Vector3 pos to terrain, I think it's normalized (0 to 1) on terrain scale across x and z. I'll post if I can find it.

See this http://answers.unity3d.com/questions/409408/heightmap-to-world-location.html

I haven't looked at the splatmap in a while, is it using the x,y

I've seen this post. Still a little confused as to how to actually implement the code for my project. It seems to be taking height map information into account, but I don't think that's what I need???

I think you'll need to combine the snippets on those pages and fill the gaps, I don't have straight code (thus no Answer, just comments). Other links that might help:
