The uv coordinate is in its position at the vertex points, but it is only approximately correct at the primitives. Divide the surface.

Thanks for the suggestions. I've used scaled sheets and gradient in the emission colour to make the centre a bit stronger. Anyway I could not set nice the edge falloff of geometry light.

I've deal with this tool recently. Meanwhile using, it has changed a lot, but the basic theory in vopsop hasn't. I could examine the distance of the line (wave axis of rotation) with an invert transform. I upload a demo hip and a video. Here is Florian Witzel's wave rig video, which can gives you inspiration:) wavetest.hipnc

Hi! If I have understood the problem, I think it's working. point_problemNG.hipnc

your welcome! Fixquat solution does not work at the animated goal geometria, because the attribute is not initialized in the popnet context.

another solution, with quaternion. goal_alignFIXquat.hipnc

I've mixed N and UP vectors in voppop. cheers goal_alignFIX02.hipnc

Try it on fbx converter. http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=10775855

with chop. G crapchop.hipnc

I have just made until the second bouncing, and now it becomes difficult. I will continue it... G raybouncePz02.hipnc

Thanks Macha!! origin("",chs("parm"),"TY") it works

I have a problem with origin expression. I can not replace the obj2 operator path with a string parameter. This does not work: origin("","chs("parm")",TY) Where is the problem? What should I do? Thanks, Gergo originexpod.hipnc

Hi Christian, I have tried your asset, it really works. Thanks that you shared this with us. I have already tried this ixDartThrowEmission ice compound with Houdini. However it is brute-force, it is not as slow as I expected. Cheers, Gergo DartThrowBF.otl DartthrowBF.hip

One other way. As far as I think is better. G sopsolver_gasresize.hipnc
