It is the model that contains the data needed to texture a model, so no, you can't just replace colours with textures, in pepakura or any 3D program for that matter. Solid colours and textures do not hold the UV data needed to texture a model. I googled a tutorial, and it worked fine for them, but I'm missing something. So, HOW do I scale up that texture to make it appear the way I want it to on my drawing? (green cap, with 4 large white spots?) When I zoom in there are MILLIONS of those little things on the cap. Now the bottom is still plain and the TOP is goofy. When I returned to Pepakura I was able to select 'Material0' now, and replaced it with the same texture. Then I went back to my source drawing, selected the cap, and colored it red. I unfolded the model, then clicked 'Settings > Texture Settings' I selected the 'FrontColorNoCulling' option, specified my texture, and ended up with the picture you see. The cap and base were both left uncolored, untextured. I was originally trying to use a complex model I designed, and failed, so I tried the mushroom you'll see in the picture attached. So, according to several discussions I've seen, it should be easy to apply a new skin to a model in pepakura. Model: a Mushroom with 2 components (cap and base) exported from Sketchup as.
