Gaia try to stamp - Unity Crash


Recommended Posts


I`m using Gaia in some of my Projects and until today it worked fine for me. 

just startet a new Project wiht Gaia. Its the Version 2021.2.19f1 from Unity and the the newest Gaia Version from Unity Asset Store.  I`ve worked through Quick start and do the changes in the project for Gaia and then importet Gaia. 

With the Gaia Manager I create Terrains mode "Manual with stamper". 

Gaia create the Terrains and I can see the Stamper window. Next I choose the 2k Plain Stamp from Gaia an Fit it to the terrain.

When I push "stamp" the stamper starts, and its processing a moment, but then there is a red sign (without error message) and Unity close immediatly. Sometime there is also short time black screens. Due to no error message I don`t know what to do? I found this crash log from Unity but I can`t really understand whats wrong 😕I`ve tried restart(s), setup a new project but again the same.

I am not seeing anything wrong in the crash log. 
Have you tried a smaller terrain size to see if a simple terrain like tiny or small works? 

You can try to clear your Unity cache as well, which might help. 
Even though its a new project sometimes this helps. 

Are you using a template from the Unity hub (anything besides the basic 3D template)?
