Diego A Grimaldi Posted August 16, 2014 Share Posted August 16, 2014 Hey everybody, I'm trying to make a procedural model of a cigarette ash (possibly procedurally animatable), and I'm kinda at a dead end. I started with a simple model with another model inside and use a couple of voronoi fractures to give a sort of cracked look but didn't get anywhere close to the sample picture. Then I tried a different approach, scattering point on a cigarette-like object and copy stamping different noisy planes but even that didn't work (mostly for my lack of experience in modeling/texturing). I was wondering if anybody ever did this sort of model/effect. Any help would be greatly appreciated. I need to to the model, shader, and render :S Bonus points for a hip file Link to pic here: http://upload.wikimedia.org/wikipedia/commons/7/77/Cigarette_ash.jpg Quote Link to comment Share on other sites More sharing options...

Diego A Grimaldi Posted August 17, 2014 Author Share Posted August 17, 2014 Hey Don Luco, I've seen that thread, but my problem is a little different. I actually need to procedurally model the burnt tobacco/ash part of the cigarette...Just the tip to be clear... I don't really need to model the whole cigarette getting burnt...

konstantin magnus Posted August 20, 2014 Share Posted August 20, 2014 Hi Diego, I recently tried to create a result inspired by your image: - voronoi fracture a tube (using an increasing value in 'scatter sop' - >'alternative attribute') - convert the fractured pieces to roundish pieces via nurbs - subdivide the pieces and put (probably several layers of) noise on them - use suitable noise maps for texturing and - increase level of detail by using 'displacement' in your material cigarette.hipnc shows what i mean (please take it as a rough draft, its certainly just a first go) cigarette2.hipnc is ripping a tube by noise (very messy file as well) for further research you might want to look inside the following tutorials: - http://www.rohandalvi.net/commercial/ -> 'tea and cookies' (his cookie technique for cracks may be useful for your ash pieces) - https://cmivfx.com/store/506-Houdini+Embers+And+Ash (maybe too much on animation) - http://www.rohandalvi.net/free/ -> 'disintegration in houdini' for ripping - https://cmivfx.com/store/280-Houdini+Fractals for texturing good luck! cigarette.hipnc cigarette2.hipnc 2 Quote Link to comment Share on other sites More sharing options...
