In fact all symbols (+,/, etc.) except can be ignored with help of Context Ignore field in the Rules tab.

I mean that this is context sensitive l-system.
It works without brackets in the premise and doesn't with brackets.
This is the exact problem.
Note that it isn't an example of really useful l-system. It is for clearing problem only.
The rules should just draw one edge. And final string should be F.

Hi all.
Have a problem with context sensitive l-system.
Exactly:
Premise: A
Rule1: A>B=F
and nothing happens (string is not rewritten).
Without brackets it works.
Any ideas?
(In fact I need signal propagation from main branch to children (as in “The Algorithmic Beauty of Plants”, Mycelis muralis – Model II, page 88). Rules above are just a trivial example of the problem, for clarity.)

Houdini Indie and Apprentice » Unable to render texture with skin material

OK.
Going to learn VOPs.
In fact I was inside Skin Surface Shader but just wondered if there is simple predefined way to solve the problem.
Anyway learning VOPs should be useful.
Thanks for replies.

probbinsI don't understand.
There isn't meant to be a texture map in the skin material. It provides all the controls without the need for an image.
What about color variations among different body parts on human skin?
Anyway mental ray provides such functionality.
And I can't believe that it's impossible in Houdini.
May be some layering?

Well..
There is no Color Map in the Skin material (as it is in some other materials).
Also I tried OGL Texture Layers inside the material on the corresponding node.
It works in viewport but doesn't in render. I mean material renders OK but texture doesn't appear..
Can't find any help concerning this.
Suggestions? or links?

Houdini Indie and Apprentice » How to select continuity component?

digitallysaneI mean http://en.wikipedia.org/wiki/Connected_component [en.wikipedia.org] I just didn't know correct english term for it.
I don't know what “continuity components” means, but I suppose you're talking about groups of polygons (groups of primitive in Houdini) and groups of points.
digitallysaneIn fact I tried it and it selects only separate faces (in my case).
In the component selection menu you have the options to select Primitive Groups and Point Groups. You click a poly and the whole group is selected.

Well.. I've found it .
It can be done by ‘Select connected geometry’ option in the Geometry Select Mode options.

Hi, all!
Strange problem.. It's so simple in Maya or Blender..
For example if I import human model from MakeHuman there are several continuity components (body, head, eyes etc.) in ONE geometry.
How can I select exactly one of these continuity components? (I mean to select all faces of the component.)
Thanks in advance.

Thanx for reply.
But in fact the problem was that I installed Houdini under non-root account.
After I reinstalled it correctly all works fine (after disabling compiz ).

Download houdini 9.1 (for Ubuntu 7.10). Install it. Run. Press ‘install a non-commercial license’. Get error:
'Error installing key: LICENSE Generic Houdini-Master-NonCommercial ….
Unable to read/modify license file. …'
In License Administrator see:
*The license server is running.
*The license server may not serve licenses.
*The license server does not allow license modifications from this machine.
Also note that after installation I did not find sesinetd in the /etc/init.d and ran it from /home/ilya/hfs9.1.124/houdini/sbin
Suggestions?
Well.. and Where is this license file?
