Really interesting and cool Filter ThreeDee. Thanks for sharing!
ThreeDee, today I was using your Multireplicate filter and I think it needs a little update due a "bug" in the shadows.
Try the steps below to see if you get the same issue:
1) In Photoshop make an 3000x3000 image and fill it with red background and don't make any selection;
2) Now apply Filter Forge with your filter by using the 1st factory preset;
3) Note that over the orange squares there is a "lost shadow" over them.
The way I got to fix it by changing the contrast value from 50 to 20 in the 2nd Perlin Noise 1.017 (from top to bottom | from left to right). Now, I'm not sure if it will fit for any situation. ;0)
Cheers.
Lucato.
