Hello,

I am doing a tutorial for sourcing fuel, temperature, and an activation attribute from points.
I am having an issue transferring attributes from some re-sampled curves to a point cloud on a grid.

I am first using a re-sampled curve with carve SOPs to create points that have these attributes. I think the issue I am having is getting these points into my VOP network. To do this I have 3 Point Cloud Open nodes in my VOP. I am then using the expression:

opinputpath(“.”, 1)

The 1 is replaces with the correct inputs. I think this is where I am going wrong but cant be sure. The tutorial says to use the expression

op:'opimportpath(“.”, 1)'

but this is giving me a syntax error. I have the point cloud open feeding into a Point Cloud Filter looking for my created attributes. The output from those are fed into a float to vector then to the Point Color attribute on my output. I am only getting 0 values on my RGB for the points. Am I doing this incorrectly?

I am using 12.5

Thanks,
James

do you just to know how you can take attrs (like Cd) from points and import these in the VOP with pcOpen ?
is it true ?
if it's true so check attached file :?

if no, Please explain more clearly :idea:
Thanks

To open points in the “Point Cloud Open” you should use below expression for first input :

op:`opinputpath(“.”,0)`

to expand on this, one of the best permanent defaults i've seen people use is to set the file parm on the pointcloud open vop to be

op:`opinputpath(“..”,1)`

so by default it uses the second input as your pointcloud. then you just need to change the 1 as needed, and you don't need to mess with unnecessary parameters or jumping between two levels.

also. sup James?

Using op:`opinputpath(“..”,1)` worked wonderfuly and I was rewarded with a pretty pyro sim. Thanks guys!

Sup Dan! I will try not to blow up your gchat with probs as I work through these tutorials….
