    Hi everyone, Herer's a little personal project I did over the last year. No keyframes where used for the animation. Each movement is generated through physical simulation or procedural noise. The Bananas and Pears are done in H16.5 using CHOPs controlled Bones and then fed into a FEM simulation. All the other fruits are done using H17 and Vellum. ÖBST: "How would fruits move if they could?" Hope you like it.

    if you want branches and fruit to mutually affect each other you can use stitch constraint or glue constraint attach to geo is just one way constraint

    here, I've randomized your sort and also offset in random edges selection...you can see purple lines going to both places where it's being used vu_procedural subdivide11.hiplc

    just wright position to attribute and after moving to origin apply stored position attribute to @P;

    here is an example with multiple holes of different position, rotation scale all petals are packed and reused among holes so it should be efficient even with thousands of them, the masking is happening only in the shader with the help of some attributes from SOPs to get the correct circular projection ts_mask_by_opacity_.hip

    There are so many nice example files on this website that I am often searching for. I wanted to use this page as a link page to other posts that I find useful, hopefully you will too.

    Needed to group points inside camera frustum in SOPs (to remove instances not seen by camera), googled, ended up here. Found that Volume SOP ('From Camera') ---> Volume Bound SOP is an easy way to get a lightweight polygon version of the camera frustum. Used it as a bounding object (Peak SOP to enlarge a bit to include nearby instances for bounce light) in a Group SOP and voila, job done. TLDR: +1 for Volume SOP ---> Volume Bound

    After a year, I have another project to which I can share the source files. (link to the previous one) It is nothing revolutionary or special, it was partially done in After Effects, but I hope that it might be helpful and inspirational for somebody. Video from the 270° presentation: https://vimeo.com/246338905 Source .hiplc files: http://bit.ly/2BO4Rj3 Everything I can do in Houdini is based on the help and knowledge shared by the community. I can do it thanks to you guys! Thank you very much. Thanks goes to great guys from http://www.xlab.cz, I did it for them! Preview:
