Hrm, no that is not what I mean't.

Sorry if this was already mentioned; Improvement on modeling tools. A little better workflow, I love I can go back and literally edit the contents of the nodes, sometimes the results can become unpredictable, in that sense, it's best not to make changes. Overall compared to Maya, whereas the only solution is undo; no surprise technically Max is excelling in terms of technical features, it's core was better designed. I still favor Maya over Max but anyhow little more efficiency in Houdini modeling

I'm having problem simply understanding the documentation; The random function in VEX, how do I read it and apply it ? float random(int position) Isn't the correct VEX code; float random(@P.y) for a simple example on a sphere and that would randomize the points on a sphere ?

@P.y = noise(@P) * ch("amp"); Is it possible to turn the above VEX code to display a literal math formula ?

?

I never said I wasn't reading or going to re-read your post, I just said I want to go back a few steps, that I didn't look into. Let me go over the thread once again !

Wait, I'm going to go back a few steps, there is another way to use Paint SOP ?

I assume you only need to use, for example, the temp variable vector chv if you are creating the variable, not if you are applying it, as in the last two VEX code examples ? I thought noise needs three values, there is four if you including @P; I'm probably completely wrong in the sense that you need three values. I don't see the big difference between chv & ch ? How do I keep the grid stuck at it's position because currently it moves on the Y in the world ? Thanks for help up to this point, truly am appreciative.

oh for crying out loud, now it works. I had HDR Rendering option off.

Thanks for helping, maybe someone else can chime in.

It can't be, the scene by 6ril works. 6ril used UV projection but stated you don't have to, I proceed to re-create the scene and I can't paint on the mesh with replace / add ?

I understand but I don't see anything when the mode is set to replace either !

Yes of course. Here is a new scene. as_paint_prob.hipnc

chf is (channel,frame) which I don't want the frame @P.y = noise(0,ch("noise"),0); noise takes three parameters, if the channel noise is controlling the Y which is suppose to control the noise ?

I'm trying to learn and understand Without hacking away, never know !
