signet Posted July 12, 2006 Share Posted July 12, 2006 Just did this little test and was pretty pleased with the results 15 mins work thought i'd share it with you Mike Link to comment Share on other sites More sharing options...
JamesTaylor Posted July 12, 2006 Share Posted July 12, 2006 looks nice, care to share the details of your method a little?? i'm guessing either vray disp with opacity map or a particle solution with the particles asssigned geomety shapes? Link to comment Share on other sites More sharing options...
signet Posted July 12, 2006 Author Share Posted July 12, 2006 Sure i modelled one ivy leaf (about 8 polygons) and used that as instanced geomtry with particle flow using position object (on a un-renderable plane ) and speed space follow with some rotation divergence i actually used 2 planes set back from each other to create some depth there. mike Link to comment Share on other sites More sharing options...
JamesTaylor Posted July 12, 2006 Share Posted July 12, 2006 thanks, that interesting - seen similar methods using particles and instance geometry in tutorials, never had chance to have a play to date works very well tho. have you tried it inconjunction with a GI scene yet? would be interesting to see if its feasable in production use?

tecton3d Posted July 12, 2006 Share Posted July 12, 2006 great technique, it's very convincing ~ thanks for sharing! @ 286k poly's with only that much coverage (area,volume) will bring a GI calc with a full scene to its knees but I'm sure the lads over @ Uni have a few cows to render on:D Link to comment Share on other sites More sharing options...
kippu Posted July 12, 2006 Share Posted July 12, 2006 well i think its rendered in vray ...thats a nice thing at 51 secs Link to comment Share on other sites More sharing options...
tecton3d Posted July 12, 2006 Share Posted July 12, 2006 well i think its rendered in vray ...thats a nice thing at 51 secs no matter rendering engine ~ for that size of an image without anything else in a scene 51 seconds is acceptable but not super try covering the facade of a building in it an see what happens then... I'm just saying it won't be a quick render. This effect/technique will have to be used wisely (which I'm sure it will)! signet ~ any plans to animate/grow the ivy? esp since it's already in pflow : ) cheers!

signet Posted July 12, 2006 Author Share Posted July 12, 2006 Just to let you all know the render above is GI irr map and light cache. that was with 5500 instances the next thing i did: I have made a wall 24m high and 24m wide. (big wall) turned the PF source up to 80000 instances and rendered it from a view where i can see it all in shot and it rendered in 51 seconds. not bad at all ( to be honest it crashed a few times trying) Link to comment Share on other sites More sharing options...

JamesTaylor Posted July 12, 2006 Share Posted July 12, 2006 so i presume it could also be made into a vray proxy object to help sort out the crashes that were occuring? or does the fact that these are particle instances effect that possibility?

I'm curious to know about the particle instances and stability... ? Link to comment Share on other sites More sharing options...
