hi,
When i use mentra i can't understand the relationship of Pixel samples and Variance anti-aliasing. Min max ray num is variance ,but pixel samples is constant value. How they affect each other ?
thanks!

hello,
I ‘v an image with alpha channel. And i want use it in for example Constant Material color map. but the alpha is not appeared in final render pic. If I use it in Opacity map ,the shader use whole image not only it’s alpha channel .
Are there some method can choose which channel to be used in MAP parameter such as “$HIP/my.png:alpha” or “$HIP/my.png:red” ?
thanks!

hi,
Can't use variable like “ rand($PT) ” in pop*** dop to randomize parameter?
If can not ,how to do the same thing?

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!

Thanks for replies!
Just as tamte said, i use them in Group parm on Sop node. It works!
Antoher question, how to use @P.y > @P.x in Sop Group parameter?

Hi,
Could use parameter channel in group pattern?
I tried @P.y>ch(“mych”) but it not worked. Any way do it ?

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.

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,
In this help doc:
http://www.sidefx.com/docs/houdini13.0/model/lock_nodes [sidefx.com]
This doc said , for some node types can Delete History.
I want to kown what type node can delete history by RMB menu?
Thanks!
