$PR in soft transform not accessible

[fragmentzero]

Hello,

Is there any reason why $PR and $PT are not available in parms of SoftTransform?

Or is it just me?

Thanks

for this node this variables are not built in c++ code already

 

we hope they will implement that in h14

Ok. I'll test it in H14.

 

Thanks

Nope. They haven't implemented this in H14.

Just curious, what are you looking to use $PT for, in Soft Xform? At the moment, I can't think of why I'd want some sort of per-point-variation soft transform, and not just use a VOP.

 

I'm not saying you're wrong to want it; it's possible there are good alternatives to get the same functionality, or it could be something that's just been overlooked in development. If a bug/RFE hasn't been filed, it's especially likely to be overlooked (as active as developers are on the forums, they aren't able to see/address/remember everything).

Hi Chris,

 

I have a setup with bunch of merged curves as input. Per curve (primitive) I have a soft transform radius encoded as primitive attribute.

Now in the soft xform I wanted to read per-prim radius and apply to the points of merged curves.

I can't do ForEach because before feeding into soft xform I am connecting the curves at their intersections, and ForEach somehow destroys those connections.

 

So, I tried to do, prim(opinputpath(".", 0), $PR, "radius", 0)

This failed due to $PR not available to soft xform.

However if I used whatever primitive number 0,1, 2..., it works fine but applies that radius to all the prims.

 

In the end, I ended up doing soft xform before connecting the curves which worked for my purpose.

 

Thanks
