fixing bugs in H

[mic]

hello! i'm fighting against likely bug in H. - every time i open the hip scene i need to re-cook and re-select some nodes, cause their transforms are not correct. that is not very comfortable) i wrote few-lines-script in Hscript - smth like that:

set nodes = '"obj/geo2/metaballWing" ..........'
set groups = '"obj/geo2/WingGroup" .........'
set transforms = '"obj/geo2/WingTransform" ........'

for i = 0 to 4
	opset -C on -r on -d on `arg($nodes, $i)`
	opparm -d `arg($nodes, $i)` -v tx ty tz
	opset -C on -r on -d on `arg($groups, $i)`
	updateui
	opset -C on -r on -d on `arg($transforms, $i)`
	updateui
	opparm -d `arg($transforms, $i)` -v px py pz
	opparm -d `arg($nodes, $i)` -v tx ty tz
	opset -C on -r on -d on `arg($nodes, $i)`
	opcook -F `arg($nodes, $i)`
end
opset -C on -r on -d on obj/geo2/popnet6

the key command is 'updateui' - without it nothing works. But if i want render from commandline, cmd doesn't understand 'updateui' of course. What should i do in this case?

(the reason of 'updateui' is that without it everything works only using line-by-line execute (in Textport)! full .cmd file didn't work. so i needed some 'pause' command and 'updateui' seems to be helpful in all cases except render from cmd)

I wonder if you have some kind of conflict (like a cyclic dependency) which is causing your objects to evaluate incorrectly? Sometimes I find the best way of finding this out is to use the Performance Monitor and look for errors that get printed into there.

So, try this: load your scene with "houdini -n yourscene.hip", to start in the Manual cook mode. Open up the "Windows> Performance Monitor" and enable "Enable Output". Change the cook mode to "Auto". Now scour the output for errors in cooking.

i didn't find any error, but nevertheless thank you for your advice!

and while scouring output i thought that the reason may be that the nodes aren't connected to each other? i have the transform node ('WingTransform') somewhere and metaball (not connected to it, of course), which center is 'ch("../WingTransform/px")'..
