GeNa Terrain Extension: throwing NRE (The object of type 'RenderTexture' has been destroyed but you are still trying to access it.)

[mroshaw]

Hi!

 

Using the latest version of GeNa, 3.4.6.

 

I'm creating a Road Spline and using the Texture extension. I've noticed that once I've applied a texture, if I come off and then back on to the Texture extension, I get errors in the console and the mask preview doesn't work. I have to close the Editor and re-open it to get things working again:

 

MissingReferenceException: The object of type 'RenderTexture' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.

Hey @mroshaw,

Thank you for reporting this issue with steps on how to replicate it. I've actually been trying to find this issue for a while now. If you could assist me in replicating it, I can have it fixed pronto. Could we start with the version of Unity you're using and the kind of Terrain textures?
