Is there a way to generate a linear curve using CHOPs?

[magneto]

Hi,

 

I looked everywhere but couldn't do it. I barely mocked one using Wave CHOP's ramp but it's not good or controllable.

 

Basically I want this kind of linear curve:

 

Thanks

If you're looking for a linear function of the type `f(x) = ax + b`, then you had it right with the `Wave` node. If you set the type to `Constant`, then you get `f(x) = (ramp slope * x) + amplitude`.

 

In other words, if you set the `Ramp Slope` parameter to 1 while leaving the rest by default, then the value from your y axis will increase by 1 every second.

Thanks Chris, it works great

channelCHOP with $F , or do I miss something here

Channel CHOP SOP? I want to modify it in CHOPs also before exporting and need to have the value range from 0 to 1 for the entire animation range.

I believe that sanostol meant the `Channel` node from the CHOP context. This works too—you could put an expression like `$T / $TLENGTH` in the value parameter to get the curve that you seems to be after.

yes channel in chop context, any timedependend expression does the trick
