lot to read, study and understand... great :-)

@Librarian: also not bad ;-) thank you

hehe, as always great and thank you

a small problem: an object, i.e. a sphere, normals wich are pointing downwards and following the surface. So far so good. I want to animate flowing waterdrops and so I need meandered vectors for vel. the problem is the volume vop where I want to realice the flow with a curlnoise. As far as I activate the volvop the vel get straight again. I dont find the mistake. Also the visualizer dont work. Please have a look at the attached file n_flow.hip

yep You was wright. Had a zoom on it ... Jesus...grin

How could I activate the visibility of a node if I am not in the main take?

dont know what the answer was but for a fast inspection just pin the thumbtack in top of your scenview before you dive into the DOP

in the attached basic scene I dont get the aliasing artefacts away. Tried so much things... no problem in RM. Would someone mind to check the file and give me some hints for the rendersettings? thanks in advance. nested_dielectrics_finish.hip

Hi Sir, yep know yours, that was the reason I asked here cause I think I saw it in your pragmatic-vex.. ;-) Would you share how to do that?

Hmmh.. maybe it could help if you pack your boat?

@librarian: the hint wit Jakub Spacek helped me a lot. Great. Thank you.

Not sure, maybe Give the path a variable wich you declare before or via the GUI of your HDA.

For what you are want to use it for? Maybe you could use a SDF... also a point approximation with VEX is possible. Could you post your hip with some explanations what you wan to do?

ok here: 2D_fluid_Logo_01.6.7.hip

I have a particlesim where the pointcolor is driven by the volumedensity from a smokesim via an attribfromvolume node ramp. Now I want to get the driven color on a particlefluidsurface. How I have to built the shader for it respectively wich eventual works ahead in the DOP/VOP land are necessary? 2D_fluid_Logo_01.6.5.hip
