1. ## How to use mask field node in DOP Network in RBD sim?

Thanks guys this was really handy, I was also wondering how can we mask forces by other attributes. Say you wanted gravity only on particles that had reached a certain velocity.
2. ## Couple Vellum questions (pressure by att. and attach)

Hey for the first part of your question I can suggest this video. He shows how to create and attribute to drive the pressure. You have to create a sop solver in the vellum solver to transfer the attributes. For the second part you just need to create groups on the body and arms and use the vellum constraints like attach to geometry and then you can use your groups in there.
3. ## Control forces by conditions

Hey I had this come up a few times today and I was wondering what was the best way to tackle it. I am doing a melting sim of an object thats floating in space. I am using temperature to heat the FLIP and start the melting process. if use gravity then the whole thing starts moving from the start and not just the heated parts. I was thinking if I could just apply the forces based on temperature then that would would be ideal. I tried something like this in the pop wrange but its giving me erratic results. float hot = @temperature; if (hot>1) {@v *= 3;}; Also whats the equivalent of the the geometry spreadsheet in dops, if I wanted to see the values of the temperature or any attribute. I can visualize as color but would be nice to get some numbers. Cheers!
4. ## vellum weld selected edges

Thank you! I should have tried it on a simple geo like yours. It was basically an issue with the geo.
5. ## vellum weld selected edges

Hey I was wondering if any one knew, when you take a geo and shatter or fracture it into pieces. The weld constraint in vellum seems to know exactly how to attach them back together. However I have a piece of geo thats presplit along the edges along the edges in a specific pattern and I can seem to get the weld to recognise the edges and weld them together. I have created a group (in both edges and points) thats just the outer edges I thought that would work but no dice. Thanks
6. ## Installing Qlib Package method

I had a similar issue where some of the the features were loading and I could see the tools but when i added a node to scene it would say the definitions were incomplete. When I loaded the example files I would get the same error as well.
7. ## Installing Qlib Package method

sorry guys i couldn't get it to work and then I forgot about it.
8. ## Installing Qlib Package method

Thanks but i am trying to do the package method since all my other plugins are installed that way. but maybe i should just use this way.
9. ## Installing Qlib Package method

Hi guys I am trying to install qlib for houdini 17.5 using the package method. The instructions says Extract and move it into the Houdini config folder in your home folder and Copy the qLib_linux.json (or qLib_windows.json) file into the packages folder that didnt do much so i added my path to the folder in the last line."path" I got some of the tools to show up but its not loading the other OTLs. I am guessing I need to add the path to other sections but I am not sure where. { "env": [ { "QLIB": "\$HIH/qLib-dev", }, { "QOTL": "\$QLIB/otls", }, { "HOUDINI_OTLSCAN_PATH": "\$QOTL/base;\$QOTL/future;\$QOTL/experimental;\$HOUDINI_OTLSCAN_PATH", }, ], "path": "\$QLIB", }
10. ## Distance fall off

Thanks for pointing me in the right direction, after a bit of trial and error and copying of random bits of vex I have something working althought it dosent make sense to me 100%. i have attached the file in case some one find its it useful. finddistance_working.hipnc
11. ## Distance fall off

seems the file didnt upload correctly. finddistanceB.hipnc
12. ## Distance fall off

Hi I am doing the entagma tutorial where he is blending from low poly to high poly object. In their example they are using a single point from a sphere to create the blend as in the image below . I would like to use a piece of animated logo to reveal between the two. Using bit of vex I found on this site I think I am getting the distance from sphere to each point on the grid but when I visualise it as Cd. It only seems to be taking a few points into account. What I expect is black circle around the sphere. Thanks finddistanceB.hipnc
13. ## Mouse causing hand wrist pain

Besides the wacom I also recommend doing some Yoga or just some stretching at regular intervals. I also had wrist and shoulder issues and a combination of these things has really helped. If I have to use a mouse I make sure its a good one with a bit of weight on it.
14. ## Non commercial to commercial render service

I dont think that would be possible as the file types are different. Even if there were willing to they wouldnt be able to open the file. You can convert to apprentice files to Houdini Indie.
15. ## Custom attract

Thanks. This is completely different from the process I was trying , good to see a different way.
