I'm using Sketchup as my 3d software (free and not too complex. Something else I noticed after I posted in here originally, those thousands of tiny dots showed up again during posts 2 and 3. Although I've been making paper models for a while now, I haven't actually designed all that many. Wow, thanks for all the background information guys. It also only likes 2ⁿx2ⁿ size images, so if you use an image say 345x456 it will attempt to resize it with its internal function, you need to resize your images with a better program if they are not a 2ⁿx2ⁿ size.īTW, it normally takes more time to texture a model than it does to make the model, it's not difficult, just time consuming, especially when you need to make the texture from scratch. In setting, other setting, advance, there is a checkbox labeled "smooth texture image", if it is checked it will attempt to resize any image below 512x512 to 512x512, my suggestion is to ALWAYS uncheck this option as the image it produces is REALLY bad (a monkey with a turd could do a better job) A U value of 0.5 will point to the half way point in the X axis no mater what size image you have.īit of a warning for pepakura, it has a horrible image resize function which will always mess your textures up if your not careful, it's something like a cross between a bicubic sample and gaussian blur. The numbers stored with the model, the UV co-ordinates, used to map textures onto the model are just X,Y co-ordinates for the image, they are stored as a unit vector (ie 0 to 1) which means it doesn't matter how small or big the texture is, the X,Y co-ordinate will be at the same relative position within the image. I think the threads you read were meant for replacing textures with re-coloured versions of the same texture.
Sometimes 3D programs will automatically 'map' an object you create with UV co-ordinates to make life easier for you so it may seem like you can just replace colour with textures, but in general you need to map the textures onto the model before you export it to pepakura, (in just the way you did) pepakura has no ability to do this at all. 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.
