Hi everyone,
I have a big issue about exporting data from vexpression context.
I used vexpression to set the velblend parameter in the "popadvectbyvolume" node. So I can advect particles differently along time.
But I'm not sure what result number I have, so I want to export this value to check it out in the geometrie spreadsheet.
I found this line in Houdini Help: export float @mytest = 0;
So here is my code:
#use a parameter to set the velblend
velblend = @activate;
#use a count to set the velblend differently when I want to if(@count >= 3) { velblend = 1/((@count/3)*5); }
#want to export the final result to debug export float @velblend;
My popnetwork works fine (my particles get different vel along time) and I don't have any error.
But when I check the velblend attribut in spreadsheet, it stay to 0.0
So I tried different syntax like:
export float @debug = velblend;
export float @debug = @velblend;
export float @parm_velblend;
But each time I had an error : "velblend" is not a valid default for this prototype...
I'm getting crazy right now!!
If someone could have an idea, it could be great!
Thx a lot.
Cheers
