Yuanfei Posted May 27, 2015 Share Posted May 27, 2015 Hi,I'm currently working on a blood scene. My goal is to make the blood slide along the surface of head, then drop on the ground at a certain position. So far, my flip went down on the ground strightly without any attachment with the surface. I'm wondering if it's a problem about my surface position, emitter style, or phisical settings. Now I'm trying to direct the flip by the custom normal, but I couldn't get it work. Could anyone give me a hint to approach this kinds of effect? thanks. blood_spiting.hip Quote Link to comment Share on other sites More sharing options...
Yuanfei Posted May 27, 2015 Author Share Posted May 27, 2015 (edited) Hi guys, Thanks all. I solved the problem by modify the Normal Scale under the Stick on Collision tab. Normal Scale - Scale the amount of velocity adjustment in the direction normal to the collision surface. I couldn't figure out how it works, but here is the result. Please let me know if you have any info about Stick on Collision section, thanks again. Edited May 27, 2015 by Yuanfei Quote Link to comment Share on other sites More sharing options...

Yuanfei Posted June 15, 2015 Author Share Posted June 15, 2015 Hi Diego, sorry for late reply. Here's the scene file. I found it couldn't easily be solved through the stick node after I check this discussion, http://forums.odforce.net/topic/15197-houdini-viscosity-flip-stick-on-object/?hl=%2Bflip+%2Bfriction. I was trying to make the blood slowly slide on the surface. Since it's a fast-moving geometry,I don't know how to deal with. Also the face geometry is not in use, so I couldn't use the wetmap trick. Please point me a direction if you have any thoughts, thanks. blood_setup_odforce.rar 1 Quote Link to comment Share on other sites More sharing options...
