You can still old-school it by using an animation channel, keyframes at 1 and 100 (and any inbetween) then use the ‘chf()’ function to look up into that curve. That's what all use grey-hairs used to use and still do when the Ramp parm lacks the interpolations you want.
hi pbowmar ,
chf() may not be driven by different point attribute in Vop network. but ramp can do it.
In SI, FCurve is very useful for tweak particle per-point attribute.

Hi,
There is FCurve node in ICE that like ramp node in vop. But I find Ramp node have only linear and ease-in-out curve mode. I want make a fast-in slow-out curve in VOP Net. How could I do?
Thanks!

Hi,
I want a unwrap uv for sticky ,and second uv for rendering.
In SI you can create multiple uv projections for same object. How to do this in houdini?

I think the SI UI's most advance is Unicode Support. I can use non-english character in everywhere such as object name, file browser, comment and so on.

thank for replies!
The problem using group/stream is that the stream rule is base on Testing not Trigger.
For example: In pop stream if @P.y>5 switch new stream, but when @P.y <5 it auto switch back. In ICE a event (P.y>5) triggerd, it will keep in that state even P.y <5 .

Hi,
Are there some equivalents to ICE State Machine? With ICE StateMachine you can switch between different states with trigger and do different simulation in each state.
Thanks!

hi,
Now houdini can't show/input wide character in UI. Does anyone know if are there some plans for Unicode UI support ? It's very important for non-english user.

Why does calc only one nearest light ？Do NOT all lights contribute energy to the sample point ?
Thanks!

3.For each secondary ray, Mantra uses a 3D tree search algorithm to find the surface or light nearest to the angle computed by the BSDF
