JohnArtbox Posted January 5, 2004 Posted January 5, 2004 Hi, Been too busy enjoying the festive season to post much, but I spent a couple of hours trying out a different way to quickly create heads. I was after a carved puppet feel and I think it worked, especially given the time. Don't know how well it will animate. I had to try and avoid hooks, three point and five point patches, because they don't work with displacement maps, but I think you could just plan these in areas where the displacement is unnecessary. ciao Quote
CRToonMike Posted January 5, 2004 Posted January 5, 2004 cool beans! Why you could even create a very simple biped figure and then apply diplacement maps to them for a crowd scene... anyway, looks good. Hope it animates well1 mike r. Quote
binder3d Posted January 5, 2004 Posted January 5, 2004 That looks really cool. You said that you have to avoid hooks, three point and five point patches, because they don't work with displacement maps - why dont they? And how can you fix this or at least work around this. Does Hash know this? Quote
zacktaich Posted January 5, 2004 Posted January 5, 2004 You did that all w/ displacement maps? You Rock! Quote
Phil Posted January 5, 2004 Posted January 5, 2004 That looks real good, I'm interested to see how it animates too. Quote
John Keates Posted January 5, 2004 Posted January 5, 2004 Wow! I never saw such good displacement mapping come out of AM! Have they changed the way it works or something? Are you using v11? Quote
zacktaich Posted January 5, 2004 Posted January 5, 2004 I think we need a tutorial, If I knew how to do this my models would turn out a million times better, and even if not it would help making characters w/ extremely fast renders Quote
JohnArtbox Posted January 5, 2004 Author Posted January 5, 2004 Hi guys thanks for the commments. Answers: Christina: Hash knows about the the displacement limitations. It's one of those catch 22's. I don't think fixing it has a high priority because not many users use displacement maps, and not many users use displacement maps because of the inherent difficulties and limitations. As a workaround I just make sure that the displacement map is painted 128 grey on the problem patches and the displacement map has no effect. John: I don't think they've changed displacement maps for a while. The trick, for me, is in realising that each patch is subdivided into a 4x4 grid. Don't add too much detail or it will muddy the displacement. Also if you add features with the grain of the mesh(ie parallel to the mesh splines) then you'll get a cleaner result. It's a 10.5 render. zacktaich: I don't know if the renders are much faster. Displacement and bump both slow things down a lot :o). But can you imagine how dense the mesh for this character would have to be otherwise? And what pain it would be to modify? It's almost like having a simple weightmover built in. Here are the maps. The colour map is just the displacement overlayed on a skin tone. Also the eyes should be dark to the edge of the patch which would add definition to the lids. If I take it further I'll add coloured lips etc. Clockwise from top left Colour, Displacement(used for specularity as well), Bump and displacement overlayed on mesh. I used the cylindrical application for the decal. Quote
zacktaich Posted January 5, 2004 Posted January 5, 2004 I think turning down the specularity would make it look better! Quote
zacktaich Posted January 6, 2004 Posted January 6, 2004 [quote]Displacement and bump both slow things down a lot[/quote] Tell me about it, I just did a very basic test, and look at the rendering time. 105 hours? is that all? Quote
JohnArtbox Posted January 6, 2004 Author Posted January 6, 2004 Something's wrong... my head at 320x240 portrait full screen takes just under one and a half minutes using a 16 pass multipass render with a Twin Skycast light. It's not a fast render, but it's not that slow either. Quote
Zaryin Posted January 6, 2004 Posted January 6, 2004 It looks pretty good to me. I would love to use displacement, but I am going to have to build my character with hooks, 3, and 5- point patches hidden in areas to get it to work. Hopefully, one day they will fix the problem. Quote
johnl3d Posted January 6, 2004 Posted January 6, 2004 very nice ..displacement maps can be fun..by varying them amount over time it can create a nice morph johnl3d Quote

Iham Wrong Posted January 6, 2004 Posted January 6, 2004 For some reason he makes me think of Easter Island. Hmm.. talking rock with expressions. :) Quote
xor Posted January 7, 2004 Posted January 7, 2004 AWESOME!! It's nice to see someone making excellent use out of displacement maps. This is good to see a nice unique use of it as well. It would be nice to see a set of heads done this way. Quote
Hash Fellow robcat2075 Posted January 7, 2004 Hash Fellow Posted January 7, 2004 [quote]Here are the maps[/quote] Very impressive results. The map reminds me of the face on the Shroud of Turin. Gee, you don't suppose... Quote
Ross Smith Posted January 9, 2004 Posted January 9, 2004 Very cool! You've got the carved puppet look down. The highlights look good, I think... it's like the wooden head has been painted and varnished. Really cool effect. How do you think it would animate, though? Quote
