@thecabbagedetective What’s happening in your repeating blood spatter thing, is that the size in the mapping node is smaller than 1, so the texture scales down and repeats. Here’s how I would approach it:
1. Texture paint a blood spatter (so you have the most control) and don’t worry about the color. This will be your mask that defines which places will have blood and which don’t, so just make it black and white.
2. Make a simple blood shader and mix it with your bricks using the mask you painted as the mix factor.
3. Make sure you have some real displacement and/or plug in the normal map of the bricks into your blood shader, so the areas that have blood won’t be completely flat.
