Custom Texture color blob Issue

[armifer18]

Hi all,
I am new to the modding scene and have run into a strange issue. When my custom textures are loaded in rimworld various parts of them appear to go grey as shown in the photo below, vanila shotgun on left for reference. has anyone had this issue before or know what may be causing it? A google search and forum check did not turn up anything when i went looking. The textures were made using GraphicsGale and are 64x64x24.
Thanks in advance for anything

Is there a specific item in that screenshot you're referring to, or all of the custom guns? It appears to me that they've all got more small details and things on them, which don't show up well at that resolution. Also, I think the sprires might be lower resolution than the base-game's sprites - maybe half?

  DING DING DING!!! and the prize goes to AileTheAlien, I have just run a test increasing texture sizes to 128x128 and the grey blobs are gone. Thank you Alien for suggesting resolution as a point of interest. This issue is now solved
