Procedurally Modeling A Raspberry

Mo has recently started learning Blender. (Don't worry - we won't ditch Houdini. We just think Blender makes for a nice addition to our toolkit.) And while watching a certain popular donut tutorial, it became painfully obvious that sometimes procedural modeling is king.
As is the case with raspberries. Once you analyze which parts make an individual raspberry, it's straightforward to model one procedurally in Houdini.
Additionally the procedural nature of our berry allows us to generate a wide variety of different berries by simply adjusting our setup's parameters.

YA SO PAIN IN THE ARSE

[@rutgah]

The longest 17 minutes of my life. Thank you for making Houdini scary again;) Great tutorial though!

[@BryantBuralTV]

Your voice is so soothing. I was torn between learning and falling asleep. Great tutorial my man.

3D tutorials meet ASMR. Solidangle Arnold's page also outputs some top notch 3D ASMR content.

[@jeffwagner7292]

Awesome! Scatter basics... VDB in a solver sop for expansion and self-collision... Curve wrangling on scatter seeds... Dot product thrown in as a bonus in a wrangle... Followed by hair grooming in another wrangle... And all in a geometry object called "sphere1". Brilliant!!!!!

[@Entagma]

Wait until you see some of my production setups! :D Cheers, Mo

One of the purest and best Houdini tutorials, inspiring

[@Tiazzful]

That was a LOT of.. everything! You guys are geniuses!

[@LiMaking]

Love how you are so clear and to the point without leaving out important info. at least what it seems like for a noob like me :) this helps me understand the nodes and line of thinking better.

[@shingailibertychinamora1131]

This is very informative, loved the part you made the density attribute for the fur

[@TalkThisOut]

omfg watching you do this is fun. once im solo, its exhausting

[@vile5345]

You guys helped me so much. Definitely will subscribe to the patreon

[@arturoorgaz]

Really nice tutorial, thanks a lot!

[@arsensuleymanov7935]

Cool. Love it. Huge thanks.

[@Vivavisuals3D]

you should make a series of this stuff where you just model different fruits, this video was super helpful to my overall understanding and process of Houdini

[@kimgalifonikes7477]

Just awesome, I was trying to use voronoi texture in Blender3D but i couldn't get the cells to have even scales.

I really want to learn how to use this program now. Wow...

Awesome tutorial! But I'm trying to do realistic shader in mantra and need to bake normals ,curvature maps and others. Can someone point where to find how to do that? Thanks

Hi! How can I export this to c4d that I will be able to add materials to it and use this hair created in Houdini?

[@MrDreddnoughtOS]

Thanks a loT!!

[@samcare7753]

hey everyone, has anyone tried this since the updated attribnoise? I set my min/max to -1 and 1 in the noise value, but not getting the results on the video. any help would be great.

[@vytasrauckis6703]

I went through the raspberry redshift patreon tutorial and enjoying the patreon tutorials =). I just continued at the geometry level from here for the camera and lights. I wonder, though how you would set materials for each of the three major parts (fur, druplets and stigma) so that you can apply the hair materials where they are needed?

[@Entagma]

Hi Vytas, Not 100% sure what exactly you're referring to - in general there are two main ways of assigning a material to a geometry. The most common (in our workflow) being to assign one single material per Geo container on it's render tab. The other one is setting a material path attribute on the geometry stream itself, allowing for multiple materials per geo container. Hope that helped :) Cheers, Mo

[@Cataldus3d]

I have got an error when trying to use the solver "missing velocity", when using the vdbadvect

[@sandipandey7084]

Awesome tutorial. Is there any video about shading in houdini? It will be very helpful. Thanks

[@Entagma]

Indeed there is one: entagma.com/rendering-101-pt-16-subsurface-scattering-in-redshift-3-flavors/ Cheers, Mo

[@blackspear217]

This is a 2 year old tutorial so not sure if you’ll read this but if I were to simulate this, would you take the rbd route using soft constraints for individual berry sphere or the vellum route? Cheers!

[@raasukk4419]

Looking for the same answer, simulating raspberry with vellum and fluids itself is fine as long as the mesh is ok and not too tense but the fur part I'm not sure about... If anyone knows tips let me know.

[@xelalv]

Hi! Is there a way to freeze geometry? to get the frozen raspberry and not the growing animation

[@Entagma]

Sure. Have a look at the timeshift or retime nodes. Cheers, Mo

[@Xtronoid]

i needed to put 0.75 speed, for the first time... then boom Entagma talks like a robot from a distant future...

Awesome!!! (Y)!

[@tomjerry84]

That’s a brilliant method... I tried to make this using Vellum, but failed somehow

[@tarekmohamad1126]

Hey!! When I try to add the VDB reshape node, it gets skipped because it's not at level-set grid. And when I sim the solver, the mesh intersects instead of pushing against each other. Any idea how I can solve this?

[@kdesmet6945]

Hey dude! Not sure if you still need this but you likely plugged in your reshape node after the analysis one instead of before, hope this helps :)

@@Entagma I did watch and I asked there in the patreon page. U do not show how to do it. I guess I have to figure it out with the file. But thanks anyhow

[@Entagma]

Heyhey, have a look at the file. It's in there and easily set up. Same technique as spline rendering and hair rendering: just check "render object as strands" in the "strands" tab in your object's redshift settings. Cheers, Mo

[@WeAreBuba]

Very cool but you are too fast.Do you mind just slowing down a bit?

[@RogersPhotographyGuilford]

I need to slow this down by 10x :/

[@TroubleShotVFX]

I have no ability to follow whatever it is that you did with the splines. The coding doesn't seem to work in spite of taking my time and SLOWLY copying everything you typed letter by letter but I still get errors. It's honestly enough to make me want to give up on this program entirely seeing as the simplest of things take intense amounts of under the hood understanding to properly implement. I'm sure once you are neck deep in Houdini the logic comes together but the damn thing seems impenetrable from where I'm standing. I don't blame your solid teaching or the program itself. I'm dyslexic. And this might just be a bridge too far for me.

[@jerejerez]

I'm stuck at the same point as you. These splines coding generate always the same error at the last line about a non-existent sphere, don't know what to do it seems there's a cut in the video. I've tried everything it's very boring to give up so close to the end. Still an amazing video.

[@nanoSpawn]

If you guys need help, the code is this f@pscale = chramp("Thickness", f@curveu); f@pscale *= chf("Overall_Thickness"); vector move = xnoise(v@P * chv("Freq") + chv("Offset")) * {2,2,2} - {1,1,1}; move *= chf("Amplitude"); move *= f@curveu; v@P += move; I had the problem that, somehow, I thought that the last line was making v@P = move, when in fact it was about adding the variable to the position (totally logical, if you think about it)

[@gyulailevi]

This method is ridiculously overdimensioned. Modeling a raspberry like this is 5minutes max... 3D modeling in a procedural way seems way too complicated...

[@Entagma]

Thank so much for your constructive feedback. Cheers, Mo

[@edh615]

@@Entagma Until they start to ask you changes. Or when you want a lot with different variations, etc.

[@nanoSpawn]

It's not about building the raspberry efficiently, is about learning Houdini and its tools. You could use Blender, Max or Maya, but Houdini gives you full procedural power to it, you could easily create with this system 10 different variations of the same raspberry, or create a branch with raspberries, all procedurally and setting up every parameter.
