I've been working through to create all of the stickers and sponsors to put on the bodywork. Initially, I thought I was going to have an issue related to the UV's but I managed to utilise tools in Substance Painter to fix my problem.
To start, I searched online for the logo's I wanted to place on the car, some were available to download (referenced in the log) others I had to replicate from scratch. However, almost all of them were low resolution. Taking each of them into Photoshop and upscaling them, I had to paint over edges and tidy up blown out pixels. As shown below, the top is the copied original and the bottom is the masked out and painted over version.
Using this as an alpha mask, most of the stickers could function in this way. Then came the issue of placement. When placing the logos, most of them were across UV seams and the default setting of placing on UV would cause the logo to be cut in half or not display at all. I'd thought that by laying out my UV's in the method I had chosen, would stop something like this happening. I spent some time changing settings around and in the end, found the perfect workflow of using Planar Projection. By using this mode, I can place the logos anywhere on the car as it is utilising the 3D space rather than the UV's. This actually solves any problems when it comes to placement on the UV's and I'm so pleased with the result that I don't think creating the UV's in the way I did was necessary at all. On trickier areas, I used the surface tool to better align the piece, but for the most part it wasn't needed.
