Valentino Posted February 1, 2011 Share Posted February 1, 2011 Hey guys this is my lime digital asset am working on. The aim is the user to create lime wedges or slices easily and the UV's are procedural aswell. So far all the modelling is working perfectly and might modify it later to create oranges and other fruits. Right now only need limes for my Mojito Advert. As u can see the UI is simple but am adding more features to it later on. This is how it looks when its rendered. Early Shader test but am still working on it to make it look more photorealistic As it is now am happy with all the modeling features of it but am not happy with the lime shader. Any suggestions how to make it look more realistic? Quote Link to comment Share on other sites More sharing options...

hopbin9 Posted February 1, 2011 Share Posted February 1, 2011 Looks cool. The skin looks good, but the cut ends look a very plastic. Needs some displacement and SSS shading. Quote Link to comment Share on other sites More sharing options...
dynamoanders Posted February 1, 2011 Share Posted February 1, 2011 Yeah, really nice. Agree with Hopbin9, some SSS and displacement should do the trick. Is the bump/noise following along w/ the geometry, or is it locked in world space? Maybe do some more noise in the green texture (surface) to get it a bit more irregular. How did you do the inside texture procedually? I really like how it follows the asset changes. Anyway, good work Quote Link to comment Share on other sites More sharing options...
rdg Posted February 1, 2011 Share Posted February 1, 2011 Will there be a squeezeSOP and a muddleSOP? Quote Link to comment Share on other sites More sharing options...
Matt_K Posted February 2, 2011 Share Posted February 2, 2011 Nice stuff! Try adding some subtle, random variations overall - subtle hue and saturation differences, as well us some random bump/displacement for the skin. Please keep us posted with your progress, Matt.

Valentino Posted February 2, 2011 Author Share Posted February 2, 2011 Will there be a squeezeSOP and a muddleSOP? Not yet my friend! Maybe in the near future. Thanks for your kind words guy, any pointers where i can find more informations on SSS ? Quote Link to comment Share on other sites More sharing options...
dynamoanders Posted February 3, 2011 Share Posted February 3, 2011 Haven´t looked at it yet, but they have a deal until friday. http://cmivfx.com/tutorials/view/210/Houdini+Intro+to+Subsurface+Scattering Hope this helps cheers //Anders Quote Link to comment Share on other sites More sharing options...
thinkinmonkey Posted February 3, 2011 Share Posted February 3, 2011 It makes me desire a lime slush!!! Congratulations, nice asset! As Matt_K said, random variations are the right secret in Houdini especially about assets. I'll suggest you to rotate randomly the lime image every time you change the thickness or, to take it a step further, to choose randomly from three or five lime images, so you'll be sure that, in a case of a basket full of lemons or whatever, every lemon will be unique.

Thanks for you suggestions my friend. Unfortunatly am new in houdini so am still learning through this project, i was thinking about wat you said with randomization but still not manage to find a way of doin it.

thinkinmonkey Posted February 3, 2011 Share Posted February 3, 2011 So welcome aboard! And don't worry, I'm newbie too! About rotation of lime image, I suppose you are using a UV projection SOP to project the image, so you could randomize the Z rotation, using the thickness as reference value: rand(12543*ch(thicknessA_value_from_UI)+9.786)*360 So, every time you change the thicknessA, Houdini will generate a random number using that value (the rand() function produces a random number from 0.0 to 1.0) and it will be multiplied for 360°, so the projection will be random for every value. Well, I'll do it in that way. Quote Link to comment Share on other sites More sharing options...

thinkinmonkey Posted February 3, 2011 Share Posted February 3, 2011 I think that if you upload the asset, every one here will give it a look and, I hope, will give you an hint. Anyway I'm not so strong with Houdini custom shaders, I'm using the Mantra shader for my project, but I'll be happy to see your asset and tell you what I'll do. I'm busy now, but I'll do as soon as possible. Quote Link to comment Share on other sites More sharing options...
Valentino Posted February 3, 2011 Author Share Posted February 3, 2011 thank you my friend! This is the file, tell me what you think i should change especialy on the shaders lime_file.hipnc.hip Quote Link to comment Share on other sites More sharing options...
thinkinmonkey Posted February 3, 2011 Share Posted February 3, 2011 Valentino, I opened the file, but I got an error. I suppose you have to share also the lime .otl asset file, not only the scene. Quote Link to comment Share on other sites More sharing options...
hopbin9 Posted February 3, 2011 Share Posted February 3, 2011 You mean the file was a lemon? Quote Link to comment Share on other sites More sharing options...
Valentino Posted February 3, 2011 Author Share Posted February 3, 2011 create it again just to show the shaders, hope it works this time the pith of the lime is located in the shop in the geo node and the inside bit that i need help with of the lime is in the material! I provided the original jpg i have incase they dont work with the file i provided. dont wanna share the asset yet until i completely finish it! hope this helps thanks again for your help guys lime.hip Quote Link to comment Share on other sites More sharing options...
thinkinmonkey Posted February 3, 2011 Share Posted February 3, 2011 (edited) Hopbin9, no! Valentino, no problem for the asset, I'll give a look to the file and textures. About SSS, I cannot help, you should read threads in the shader section, I'm sure someone has asked how to do SSSin Houdini.
