I am using a print vex node to generate a texture file name with something like name%.png . the input for the node is an integer index. It works fine but how can i generate a filename with padding ??
my files are named name001.png to name999.png but my node setup generates of course name1.png ….

Try name%3d.png. I think it might work as printf in C cause thats how the vex code command printf works at least.
