Hello!
No problem
Thank you for your encouragement.
I think this larger pack terrain textures or even create walls or ceilings but free textures right blends very rare on the internet
So I do my best to add more.
In the meantime you can change yourself textures.
All you need to copy a folder, for example "inter", and then change only the "texture.bmp" file with another image 1024x1024.
Then if you put a texture (ground or wall) you can also using the buttons keyboard 1, 2, 3, 4, 5 and 6 change the 3D object in the editor (X, Y, Z) to turn it into a wall or other (everything is possible with imagination
)
Sincerely,
