Created a new project, followed the instructions to incorporate the addon. New 3D scene & terrain, saved with .res extension. I tried to add a new surface, and was planning to add an image texture to paint with, but adding an image (and apparently others as well) texture crashes Godot:

Thanks for the detailed report. It shouldn't crash. But also images must be a specific format as defined in the wiki docs. Maybe we need to filter that field to limit the options.

If you have the right format, you should be able to use the quick/ load option or drag the texture in. The other options shouldn't be there or at least shouldn't work and not crash.

Ah ok, I definitely need to check the Wiki, but the crash happened just selecting the new [whatever] texture option from the menu, before even dragging the actual image in.

[TokisanGames]

You don't need to select anything from that menu. Just drag the texture into the slot and it will work if it's the right format. If not you'll get an error saying it's not the right format. The wiki describes the format and how to make it.

To further confirm it happens woth other formats of the image tab, maybe there could be some way to hide and just have the fast load or load.

Fixed.

I had to adjust this fix. Previously, I reduced the list of possible options by requiring the format be an ImageTexture. However that only works for DDS files and refuses PNGs. I tried CompressedTexture, but that only works for PNGs and refuses DDSs. So we have to accept the parent class, Texture2D to accept both file types and many more. However, I was able to use the hint filter to limit it to CompressedTexture and ImageTexture. Now only those options appear in the list. Neither work to create blanks as people must load/quickload or drag the files in, but they no longer cause a crash.
