    I thought it fitting to post this here too ;). For better or worse, I'm launching a vfx and animation studio at the end of the week. Some of you may recognize some of the name (if you squint and look at it just right). http://theodstudios.com

    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.

    what if the self buttons were creating DOP setups inside one SOP network instead of having a Geometry node, a DOP network for simulation and another Geometry node to import the data and save to disk. It makes much more sense to see the data flow from top to bottom in one network without having to jump to different levels for no reason. maybe it's just me... grains.hipnc

    Hi everyone! The past week I worked on a personal project for learn something about hairs - vellum. It's my first project ever with hairs so I guess is nothing special but several people asked to see the hip file so here it is. Final result: Hip file (I had to recreate it but it should be pretty much the same): groom_clumping_03.hipnc

    it's pretty straightforward out of the box just use v@N, v@up or p@orient on your instancing points in such a way that resulting reference frame has Y pointing in up-down direction of your ocean (so in normal direction of the ball) and X in the direction you want wind to blow in in your file, since v@N is pointing outwards and v@N defines Z axis, your ocean deforms in a tangential direction and therefore you are seeing weird deformation here is the modified file ts_ocean_on_ball.hip

    Hi, maybe this approach might work: int count = npoints(1); for (int i = 0; i < count; i++) { vector camP = point(1, "P", i); vector dir = normalize(camP - @P); float bias = 0.01; vector hit_ps[]; int hits = intersect_all(0, @P, dir * 100, hit_ps, {}, {}); if (hits && distance(@P, hit_ps[-1]) > bias) // or just check number of intersections: // if ( length(hits) >1 ) { @Cd *= 0.6; } } cull.hiplc

    Hi. How about computing local space per primitive instead, and then get noise position from point position in the local space? Some sort of edge based UV unwrap. // Primitive wrangle. int pts[] = primpoints(0, @primnum); // Compute averaged primitive normal from point normals computed from their neighbours. vector normals[]; foreach (int pt; pts) { vector normalized_edges[]; vector pt_pos = point(0, "P", pt); foreach (int nb; neighbours(0, pt)) { vector nb_pos = point(0, "P", nb); append(normalized_edges, normalize(pt_pos - nb_pos)); } append(normals, normalize(avg(normalized_edges))); } vector normal = normalize(avg(normals)); // Compute edge tangent. vector pt0 = point(0, "P", pts[0]); vector pt1 = point(0, "P", pts[1]); vector edge = normalize(pt0 - pt1); // Compute bitangent and orthonormalize matrix. vector perp = normalize(cross(normal, edge)); normal = normalize(cross(edge, perp)); 3@tangent_space = set(perp, normal, edge); Final deformation code: // Point wrangle. int prim; xyzdist(1, @P, prim, set(0)); matrix3 tangent_space = prim(1, "tangent_space", prim); vector pos = @P * invert(tangent_space); float deform = noise(pos * {10,1,100}) * 0.05; v@P += v@N * deform; Some image sampling could work too: tangent_space_noise.hipnc

    Finally after two years of full stagnation I found the energy to fully revamp it using HUGO (which is freaking cool) and update with the very latest projects. Unfortunately 2 projects I have been working I am not allowed to share (yet)… one of them was 8 months of my life so I am pretty gutted but hopefully soon will be ok to say we did it. https://jordibares.com [jordibares.com] Most of it now is Houdini of course… :-)

    Hello all. I wanted to share my production library of tools I have posted on Github. Previously a lot of these were posted on Orbolt.com after my 2016 GDC talks. The tools were originally designed to be used in a HOUDINI_PATH style library as opposed to individual hdas. In this manner they can include a larger array of script based tools that don't fall in the paradigm of Orbolt. This toolset is generally complementary to the GameDev, Mops, etc toolset, there are only a few overlaps nowadays. There are two primary libraries of tools. https://github.com/LaidlawFX/LaidlawFX - This is the production library built up over the last decade of work that has been cleansed of studio specific work. This currently contains a set HDA's, a common python library, shelf tools, and example files on how to used the .hdas. Some fun tools in here are an Ivy Generator inspired by Thomas Luft Ivy generator http://graphics.uni-konstanz.de/~luft/ivy_generator/ . File Cache nodes that have been tested on over a dozen productions. RBD to FBX extractors, and an array of ROP tools. Also a module of python code that includes a few sub-modules such as verbosity logging, multiple hda queuing, fbx exporting, file explorer opening, and the large set of options for file caching. Additionally it contains shelf scripts so that you no longer need to use the Material Library, you can just tab and use the shaders like normal nodes. https://github.com/LaidlawFX/HoudiniEngineDev - This is over one hundred hda's to test Houdini Engine implementations in different DCC's and game engine. Each of them test a simple principle from UI parameters to different geometry types and more. Hope they help you at some point. Feel free to branch or leave comments here and I can update the source. Thanks, -Ben

    sup bb I'm not sure how you could do this without a solver, since it's accumulating rotation over time based on the speed and direction of motion each frame. I could be all kinds of wrong, though. Here's my method... I'm using the distance traveled and a vector orthogonal to the direction of travel to build an angle/axis quaternion, and adding (qmultiplying) that quaternion to the existing orient for each timestep. It's not perfect but it seems to work pretty well. Since it's basing the rotation angle on cross(dir, up), it might freak out if the ball rolls straight down. Curious if any smart people have a better answer for that. AutoRoll01_toadstorm.hip

    Here is a concept for turning blueprints into simple 3d meshes. Its basically carving silhouettes into a volume. After getting the aspect ratio for defining the volume´s dimensions ... res_front = hou.imageResolution(img_front) res_side = hou.imageResolution(img_side) res_top = hou.imageResolution(img_top) ratio_side = res_side[1] / float(res_side[0]) ratio_top = res_top[1] / float(res_top[0]) geo.addAttrib(hou.attribType.Global, 'ratio_s', ratio_side, create_local_variable=False) geo.addAttrib(hou.attribType.Global, 'ratio_t', ratio_top, create_local_variable=False) ... a wrangle is carving the silhouettes into the volume from all three sides: vector bbox = relbbox(0, v@P); float mask_front = vector(colormap(image_front, bbox.x, bbox.y)).x; float mask_side = vector(colormap(image_side, bbox.z, bbox.y)).x; float mask_top = vector(colormap(image_top, bbox.x, bbox.z)).x; f@density = min(mask_front, mask_side, mask_top); The rest is a matter of converting to polygons, smoothing and remeshing. blueprint_to_geo.hiplc blueprints.zip

    I've made this to save time loading shaders from Substance Source, but should work for any substance material. Just select the parent folder of the texture you want. Figured some others might find it useful too. It has proper viewport handling of Base Colour, Roughness, Metallic, Normal, Emission and Displacement. Not 100% perfect, but pretty damn close. Hdalc for now. Tried to upload to orbolt but kept getting an error (Invalid node type name). Don't think it likes redshift nodes. If anyone has any experience with this let me know!

    Hey Howard! Sorry about that! Here is the scene, I polyreduced a bit one of the frames of the sim to have a less heavy file to share! By the way, that mesh still has a freeSurface attribute; So you can use that gradient for nice shading effects. I forgot to say that this scene uses Redshift. v2.6.32; H17.459. Cheers!

    Hey there! Trying to be more active. Here's a WIP of a project I did for Peter Claes's Houdini class. Such a cool technique to play around with. Struggled a ton, and have lot of extra RnD elements that got gutted haha. But I learned a lot. Have to Re-Render, have some slime / rivulets for the eggs in the next render, which I have been struggling with. Initially was flip but switched to something simpler and less heavy.. Had issues transferring V for motion blur due to changing pt numbers but I'm sure someone probably could figure it out! Wanted to add one of the eggs exploding. but stretched thin on time. Will do another rnd for it. Will re-render without motion blur I think. Someone had idea of adding veins, like a neural network that activate and reveal. but I failed at that for texturing lol. I think I could brute force it with geometry to replicate it but that just seems wrong. Also I keep running into Lights inside Volumes on my projects.. makes clearing up noise pretty miserable! Will return to this project after school and expand on it.

    AMNH in NYC is looking for a TD to fill a year long spot on our next planetarium production. See details here: https://careers.amnh.org/postings/1718 We're also potentially looking for a few modelers and Maya/Houdini lookdev artists to help develop spacecraft models and planetary elements over the course of production, and a Nuke compositor later in the summer. Staff position is on-site, and freelance gigs are preferred on-site but we could work remotely with the right person. Our shows are regularly considered among the best in the field and emphasize accuracy and making cutting edge scientific data visualization accessible to a general audience. Two examples of previous shows: https://www.amnh.org/exhibitions/space-show/dark-universe https://www.amnh.org/global-business-development/planetarium-content/passport-to-the-universe This is a very small commercial size team working on a medium length production with a reasonable schedule, which could be a nice change of pace from either commercials or film, depending on which way you look at it. The content is typically pretty technical and substance always wins over style here. The TDs often end up doing a wide range of work from camera layout, to FX, to graphics programming and Python scripting. And for you Houdini nerds, Houdini is our core production package for most content creation and rendering. Email Gavin Guerra (gguerra@amnh.org) or me at my AMNH email (jpparker@amnh.org) for more info. -Jon

    couple of things: - you are finding 2 closest points, but excluding the first, since the first is the closest, you are risking the intersections with it - even checking just the first, will not guarantee no intersections, cause closest point can have small radius so it can satisfy the distance constraint, but the second or third closest can have big radius and actually intersect you new point even though it's further, so you'd have to check all points within 2*maxpscale radius - to avoid all this, use pcfind_radius() which directly checks against pscale intersections, also you can directly use uvdist() to avoid having uvmesh here is modified code and the file: int primid; vector primuv; vector pos_uvw = rand(@Time) * {1, 1, 0}; float dist_uv = uvdist(1, "uv", pos_uvw, primid, primuv); if( dist_uv < 1e-5 ){ vector pos_geo = primuv(1, 'P', primid, primuv); float rad_pt = fit01( rand(@Time + 45), 0.02, 0.1 ); int pts_close[] = pcfind_radius(0, "P", "pscale", 1, pos_geo, rad_pt, 1); if( len(pts_close) == 0){ int pt_add = addpoint(0, pos_geo); setpointattrib(0, 'pscale', pt_add, rad_pt, 'set'); } } dart_throwing_mod.hiplc

    there is a plugin which reads FBX, and it's up to Adobe to not cripple their software but open it natively to abc/fbx instead of SideFX developing something! use a subnet either click 'move to centroid' and then reset the transform values or make yourself a preset with $CEX, $CEY, $CEZ for pivot. There's no need to cram the interface with a ton of options you can easily make yourself play with screen window size. yes, it's not the most user friendly way but it works lights have a handle to orient them towards a point. (just tried it with point and spotlight but the others have that too i think) Lasso select (F3) when rendering to mplay it shows the rendertime for each frame top right corner use output node
