trying to figure out how to turn a 2D blood spatter image into a 3D object with depth

This is what I am struggling with.

as you can see from the following picture there is a sign in on the back wall of the club that reads “Fatal Addictions”

At present that is just a flat image texture on a plane.

What I am TRYING (and failing) to create is the blood spatter in 3D. not terribly prominent, but the idea is that the blood is a molded plastic relief which is maybe 6 inches deep in the real world with a backing box behind it, which would contain a light which would illuminate the blood spatter from behind (the blood being made of a plastic or glass type material).

I want it to look exactly like the original logo which I made in Photoshop for the original second life version, just all swanky and 3D and pretty

I have images of all the components (The lettering and syringe are going to be modeled separately and the whole thing put together in layers)

Here is the complete logo:

I am sure there must be a way to turn something 2D into something 3D in blender, but I have yet to either find a video tutorial, or stumble across how to do it myself and it is getting quite frustrating.

Anyone with ideas or offers of help please get in touch. it would be greatly appreciated.

Now, I don’t have any time to try something out at the moment, but I can suggest a method that may work. Import your blood splatter image into the compositor and turn it into a greyscale factor. Then, plug that into a color-ramp. Then try playing around with the flags and values of the flags to create a 3D displacement texture. Then, use that to displace a 3D object in some way (displacement modifier).
I may try this out later if I have time.
Also, you could think about finding an SVG blood splatter texture. I’m pretty sure you can import SVGs as 3D objects.

I think the best way is to use combination of dilate/erode (maybe +blur) effect applied to blood texture and it’s bw mapped version to make displacement map: blood_disp_text.blend (453 KB)

may be you could do you own splatters 3D using dynamic paint in blender

see

or even use fuild sim but more complicated and longer render time
but gives a nicer 3D model
