I am getting the bad tool warning with paint . net and I used xnresize with great results on one skin but the others look interlaced. What settings would you suggest on xnresize or what would you suggest as an editor? Also can the textures really cause crashing?
Use a good tool such as Texconv · microsoft/DirectXTex Wiki (github.com)
I’ve heard similar stories of weird corruption and scaling issues with said apps, for bulk resizing the above should work.
