Here’s another compound from my convert 3dsMax tool set. This one is very simple, it just finds sharp edges of a model and returns the values to a weight map. Allowing this to be called in the shader tree as map mask.

Low Angle and High Angle helps clip the information, increase the low angle to remove any low angles from the map, decrease the high angle to see lower angle details better.
Colour allows either black on white mask, or white on black.

Note that for this to work you will need to add your own weight map to the model. Also it relies on a nicely modelled mesh, the more vertexs the better, but if you model with smoothing in mind and use good control edge loops, the compound will work. You can freeze the model to bake the weights.

Again, use with caution, in case it blows up your computer etc.

Here’s a little compound I have just finished, part of a bigger project I’ve embarked on, converting useful 3dsMax operations into Xsi. I’ve been using 3dsMax for so long that certain simple features of the program have been ingrained into my daily workflow. So rather than find odd work arounds, it seemed more logical to try and recreate them in ICE. Good practise too.
This is the first of a long list waiting to be converted.

Noise position adds random noise movement to your objects. I prefer adding it onto a null, this is then in turn parented to another null. The compound will reset your object coordinates to zero, so if you want to move the null/object around, then it will have to be linked anyway. It’s based on frame time, so it can be added to a non simulated ICE tree.

Compared to the 3dsMax version I have added different basic noise curve types, one is random, like standard varied turbulence, then there is linear and ease in and ease out.

Strength is the height of the wave, or amplitude in maths terms. This can be used to key/fade out the noise. It can be controlled on all axis independently.
Centre pushes the noise around the centre of the start position, if not used you can get noise starting at the zero line.
Properties will allow you to change the curve type, standard turbulence, linear, or eased in and out, which creates a quick bounce effect. Frequency is just that, speed of movement, lower will be slow waves, higher will cause quick movements. Seed just randomises the curves.
Turbulence will add more detail to movement. Adjust the settings to get random jitter added onto the basic wave motion. A high complexity will add lots of small random jitters.

This hasn’t been rigorously production tested so if it starts playing up then let me know.
