A staple of my condos has been to include this technique somewhere, where the rug appears to have a 3d fluff effect to it. See below for an example - notice how the feet are slightly covered with bits of the rug.
I first saw this in another condo, Wii no Ma and loved it immediately, but the way you achieve it isn’t immediately obvious without looking through the canvas data and having some level of understanding the masking algorithm TU uses.
Here’s how I’ve been doing it.
First start with any canvas rug, use any texture for this base as it’ll be mostly covered up with our fluff layers. I’d recommend keeping collisions enabled on the base, but the effect will still work just fine if you do decide on disabling it here.
If you’re working on a large condo, it may be worthwhile to give these rugs names as selecting them will be a pain later on. I’d also recommend picking a colour at this point, as it’ll need to be copied to each layer as we go through this tutorial.
Now we need our noise texture. You can generate this easily with paint.net - full coverage and no colour saturation is what we’re looking for, remove the black layer so only the white pixels remain. Aim for a 1:1 (square) aspect ratio, resolution doesn’t really matter but I’ve got the best results with 256x256.
If you can’t be bothered to do that just use the texture below. It’s what I’m using for the guide here and has some blotches added to smooth out patches.
With that noise texture, create another rug of the same shape above it that uses the noise texture. Set the transparency mode to masked, you should see something similar to below.
Because this is our base layer, you’ll want it to mostly contain big clumps. 0.75 worked for me, experiment and find what works for you. Rotating the texture can provide some extra variety if you need it.
Align then layer it ontop of the other rug. Disable the upper layers collisions now.
I strongly recommend checking the coordinates for alignment here.
Same steps as before, but now we want a much more fine layer.
However, this time we want to double its height so it envelops most of the rug vertically.
Again, same as before - perfectly align it and disable collisions.
At this point it should be done, lock it and enjoy. Here’s the result of the tutorial below;
If it’s not fluffy enough either add more layers or increase the height scales of the existing layers. I’d recommend the latter to save on furniture items and performance. I doubt unreal engine likes handling a ton of masked layered textures and I also doubt that it’ll be much fun to fix when you inevitably misclick and move a layer.
