Teteerck Posted November 5, 2023 Share Posted November 5, 2023 Hi Everyone! Hopefully i can get some help here. I've been trying to get this effect, at first i started in Houdini playing with volumenoise and volume combines and stuff but i wasn't getting a good result and got completely stuck so i jumped into c4d with the Maxon one trial lol and it's veeeery simple and straightforward. BUT i still think Houdini will do it better and I'm dead curious about how to actually do this inside Houdini. Thank you so much in advance for any help.

Librarian Posted November 5, 2023 Share Posted November 5, 2023 (edited) @Teteerck One of million ways box iso offset 1 and second input same model(and investigate different possibility) . //volumewrangle float amount = min(1,@Time*0.02); float val0= volumesample(0,0,@P); float val1 = volumesample(1,0,@P); float offset = 50.0/(flownoise(v@P*4.1,@Time)-0.5); //float offset = 50.0*(flownoise(v@P*4.1,@Time)-0.5); @surface = lerp(val0,val1,amount)-offset; //@surface = lspline(amount,val0,val1,val0)-offset; extra Stuff on mesh Edited November 5, 2023 by Librarian Quote Link to comment Share on other sites More sharing options...
Teteerck Posted November 5, 2023 Author Share Posted November 5, 2023 Woah! That's some badass stuff, i really need to learn code it's like a super power. Thank you so much for that! I think i managed to do it though! seems like it's working but any advice to optimize or alternative it's more than welcome! Quote Link to comment Share on other sites More sharing options...

Teteerck Posted November 5, 2023 Author Share Posted November 5, 2023 (edited) Thank you!! I just tried with a font, that was my original idea and got stuck again haha, it has some weird angles so the volume makes some weird edges with the meshing. Is this fixable/cleanable? :O making the voxel size smaller doesn't really help haha thought about smoothing but i dont want to smooth the noise holes T_T Smoothing SDF seems easier than smoothing a Fog vdb.

Teteerck Posted November 5, 2023 Author Share Posted November 5, 2023 (edited) Got it! Noticed that SDF was smoothing a lot better than Fog. but the noise only works properly with fog (I think) (SDF Noise only seems to displace instead of taking off chunks like it does with fog vdbs) this worked intercepting the fog with noise and a sdf for the surface. kinda heavy but seems to work. Any suggestion is welcomed Edited November 5, 2023 by Teteerck Quote Link to comment Share on other sites More sharing options...
Librarian Posted November 5, 2023 Share Posted November 5, 2023 @Teteerck somehow for me its Faster in DOP's here you have Idea's with Files Quote Link to comment Share on other sites More sharing options...
hannes603 Posted November 8, 2023 Share Posted November 8, 2023 sharp your corners with boolean. than you get 100% sharpness sharp_edges_vdb_fracture_edge_fracture.hip Quote Link to comment Share on other sites More sharing options...
