This is actually the Solver SOP. The SOP Solver is a DOP node that allows you to evaluate SOPs in DOPs. It's an important distinction! I found this by accident while looking for tuts about the other node

Ur wish will be granted! But it'll probably be next week. I'm currently recording the disintegration and growth videos (its the last 20 sec scene in this video as a preview) I have always had vellum in my head. I always wanted to do a clothing design for a character. But I think you want a Vellum sim tutorial? Like a balloon or some sort?

Of course vellum sims can include cloth/characters and so on aswell! Depends a bit on how indepth you go, and if you do 1 longer or multiple smaller examples etc!

Thanks a lot for this Tutorial, it was really helpfull! I‘m wondering if its possible to achieve the same effect but with the torus being deformed as well? For example if a plane crashes into a soft ground and both of them gets deformed? Couldn’t find any information or tutorial to achieve something like this
@bubblepins
@bubblepins 2 жыл бұрын
You can try a different approach in achieving that, which may be a bit easier to use H19's Vellum Shape Matching to deform 2 objects crashing together: kzbin.info/www/bejne/noXJnqefr56kias Or you could use a more complex method that I have shown in the past with SDF Destruction: kzbin.info/www/bejne/l2nbeZuge8qNhJI Using the Solver SOP method shown in this video can still work, but I think when you have 2 objects that need to deform at the same time, it may get complicated with using the Solver SOP. Hope that helps!

Thank you for your detailed share! As a totally new user to houdini, i'm glad to meet such a nice tutorial. But when i test this mode in different parameter, such as set translate of torus to "-8*(abs(sin($FF*5)))", which make torus go deeper, so odd happen in the gird_object. Is that because the deformation more than the model can bear?
@bubblepins
@bubblepins 5 жыл бұрын
Hi, the -8 makes it go deeper because the negative flips the sine wave and the 8 makes the amplitude larger and also the abs() function cuts the sine wave in half so you only get the dips. Sorry hard to explain in text, I hope that makes sense. I have a blog post explaining this picture by picture starting with sin(x) = y and for each step I draw the sine graph: bubblepins.com/blog/sop-solver-in-houdini I hope that helps!

Isn't it different between solver sop and sop solver dop nodes? Thanks to the video, I knew perfectly about solver sop. But I want to know about what is sop solver. Because of this, I can't move on to the next topic. Please......

Are you referring to the sop solver node that you get inside a dopnet? The functionality is the same, except the data you get from the previous frame is the simulation data. Hope that helps.

Sorry for the late reply, for some reason UT didn't send me notifications for some of the comments. The up vector is used to denote how the object is standing. What is the object's upright standing position. Because the object could be like on its side or something.

When Im inside a sopsolver in a dopnet, I cant see anything Im working on. Is that normal? I mean it works fine when I get out, but nothing shows up inside.
@bubblepins
@bubblepins 3 жыл бұрын
I think you're referring to the viewport that you can't see anything on the viewport like the simulation or anything. It's because the sopsolver inside the dopnet requires you to cook the simulation first, just cook a few frames. Then go inside the sopsolver, you'll see something on the viewport. I believe the sopsolver only works on cached data, that's just my suspicion. Hope that helps!

@@rahulrawat952 Try to setup the VOP SDF stuff in a new fresh scene WITHOUT the sop solver. You can manually move the torus using a transform node to test if you have the VOP sdf stuff setup correctly. Then if you can get that working, then put it into a sop solver. This will it will make it easier to debug by separating it into two different steps. Hope this helps!

Great Tutorial like always! However the example is outdated. The Vop SOP inside the solver is not the best way to do it - I just used a point wrangle with this expression, nice and simple: float vol = volumesample(1,0,@P); if (vol < 0) { vector offset = set(0,vol,0); @P += offset; }

This is not a SOP Solver, this is a Solver SOP... A SOP Solver exist within a DOP context. Sorry for being picky, but it might be unclear to some.
