Weird jagged edges

I had my textures done in Gaia using a texture spawner, but I wasn’t happy with the result, too much tiling. So I installed CTS and reworked the whole thing until it looked really nice. Then I wanted to edit the terrain a little, so I smoothed it here and there, but the texture wasn’t updating. So I ran the Gaia texture spawner… big mistake. Not only did it not update, it added some weird jagged edges.

How can I get it back to normal ?

Ask in the Gaia thread or the CTS thread.

You need to understand splatmap resolution. It’s covered in the docs, but you won’t understand until you understand the basics of how textures and UV’s work.

Control texture resolution:

Also use wireframe view in viewport to see what the triangle density is like on your terrain mesh. You adjust that with pixel error setting.

Thanks for your answers.
I did a clean rebuild of my project and no longer getting the issue.
