Image Texture glitching when projected onto topo surface

Hi there, I’ve done this before where I’ve imported an image into sketchup, and painted it onto a topographic surface. When trying to do it now, the image has tons of glitches in it, and is totally distorted, rather than looking like one solid image draped onto the topo surface. I am happy to send images, can anyone provide some advice?

well I advise you to share the file, and maybe some images. but mostly the file :slight_smile:
