Disallow use of TRES format / save in a different way

Hi, I'm not an expert, maybe I'm making some mistakes, but why the terrain not rendered during project execution?

In the editor is visible...

but not when playing project...

Thanks in advance. -j

Any errors in the console? Did you write a custom shader?

[jospic]

I'm not use a custom shader...I don't know shader language so good This is console output:

There are three error in debug panel, but I do not know if they are related to the problem

[Zylann]

They look unrelated. I'd need to test myself, something stupid might be going on

[Zylann]

It works fine for me:

Could you provide an example project reproducing the bug?

[jospic]

Yes, this simple project DON'T work for me:

https://github.com/jospic/heightmap_test

I'm using a Godot 3 alpha older version of 4/5 days ago...But I could do a test with the last one. Could be a graphics card issue? Or rendering preset? Thanks in advance. -j

You didn't create a file for the heightmap. This is a usability issue, they just don't work otherwise. Basically, just like you would not create Textures directly in the scene, you can't create a HeightMapData embedded in the scene, it needs to be saved in a .heightmap resource file (go to edit HeightMapData, click the save icon, then save to file). Also, even if you could, the .tscn format is highly suboptimal to store such data^^"

Very well, it works! Many thanks, maybe, when you have time, you will do a short tutorial for beginners like me. -j
