I'm having a very frustrating problem here. I know that when most textures come out blurry, it's due to tiling issues, and fixing the ratios can help fix that. However, this time, my issue is that my texture is all an overlay -- and it looks great in TSRW:





However, in-game... ughhh:





Zooming in fixes it a little bit, but not much:





I'm tearing my hair out in frustration here. Does anyone have any tricks to getting this texture to show up in-game as crisp as it does in TSRW? Damn overlays. D:

You need to add more lighting so we can see the item, it's too dark. My first question would be how big is your texture file? And second, I think it would be better if you made only the stickers an overlay or even stencils, you should be able to color the suit case.

Really? It must be a monitor thing -- it's pretty light on my screen! But sure, I'll take another picture when I open the game again. I'm still fiddling around in Workshop to try and fix it before I fire up the game again. The texture file is 256x512. I'm not sure if I'm skilled enough to make it so that the stickers are the only part of the overlay, because the texture that I'm editing is a TS2 texture where the stickers are part of the entire texture, but I will keep that in mind, thank you. :3

Alright, here's a brighter picture:

It looks like you might UV mapped it wrong, you have to UV map it so everything is in the right proportions to each other.
You should make the suitcase re-colorable, you can get a sticker texture of the net and use that for your overlay.

I don't use TSRW so this may be off-base That said, I've seen the exact same issue with objects made using S3PE when the Mask Width and Mask Height assigned to the object don't match the size/shape of the .dds IMG used for the overlay. Your picture includes numbers for Mask Width and Height of -1. Again, I don't use TSRW so it isn't clear to me what those values mean but they are both the same which would seem more suitable for a square IMG while yours is rectangular with height being twice the width. This may not have anything to do with your issue but I thought I'd throw it out there.

Also, for what it's worth, I really like the look of the suitcase with the leather overlay you're using...it has more personality than EA's leather textures do. Rather than changing it to make it recolorable only it would be better to use two different overlays and have your non-recolorable version as one choice in Buy and a recolorable version as the second choice in Buy all within the single object. Just my two cents.

I believe that the value -1 means that the size is forced to that of the mask images actual size. You only need to change those values if for example you are using a single channel mask and decide to save filesize by using a tiny plain red mask image. So with a -1 width and height setting, one important thing to check for is that your mask image and your overlay and all those other main images are all exactly the same size as the mask, and that the mask is a suitable size for your object. This will avoid unnecessary resizing by the game.
