Hey everyone.
As so many, I am new to the whole subject and right now I am trying to get around the first steps series. I love them, they are great, but some things just don't work out…
So I thought I might start an help thread for me.
But lets get to the questions:
1. Is there somesome kind of console that tells me where exactly Houdini can't follow what I am asking him to do?
To be more precise:
in M07 In the beginning Ari shows how to color objects using a ramp. It does not work for me and I really, really can't find my mistake.
This is the code I use:
chramp(“rColor”, stamp(“../copy1”,“shClr”, 0.5) 0) on R
chramp(“rColor”, stamp(“../copy1”,“shClr”, 0.5) 1) on G
chramp(“rColor”, stamp(“../copy1”,“shClr”, 0.5) 2) on B
The ramp is inside the same point SOP node.
Stamp Inputs are activated. The switching thing works fine.
So is there a point where Houdini is telling me what he is not getting?
2.
Second Problem I had with the cookie operator (why is it called like that?)
It kinda keeps the tubes inside the candle holder, even though I set it to A-B.
I attached the file.
Thanks in advance!

ps I guess sooner or later I will come up with more questions…

For question #1, if you middle click a node, it gives you information if there were any errors while cooking it (expression errors, unexpected inputs and so on…). Now I suspect that you're getting all objects to have the same color because of the last argument in your expression that doesn't vary on a per-object basis. Try altering that 0.5 value and see if it changes your object color.
Cookie SOP comes, I believe, from an analogy with the cookie cutter thingy…
Anyway, the polyextrude sop doesn't output the back face of the extrusion by default, you have to manually enable it.
Cheers

Thanks!
The cookie SOP problem is now completely solved.
The other issue I still do not get the hang of…
The 0.5 seems not to be the issue. And I think that should be the value he should use, if does not know what to do, but hes is ignoring that aswell…
I appended the file.
Again thanks so much in advance!

Please excuse my complete lack of attention, but you forgot to put a comma between the stamp function and the integer:
chramp(“rColor”, stamp(“../copy1”,“shClr”, 0.5), 0) on R
chramp(“rColor”, stamp(“../copy1”,“shClr”, 0.5), 1) on G
chramp(“rColor”, stamp(“../copy1”,“shClr”, 0.5), 2) on B
It should work after that.
Cheers

Hey there!
I've got another question…
The Tutorial says I should set in the DisplayOptions Lighting to “High Quality Lighting”. When I do that, every Geometry turns black. Only in “Headlight Only” and “No Lighting” Mode I can see geometry.
Do I miss something?
I have an area light in the scene. Everything renders fine.
