Ivy Generator to EI
found this ivy generator recently in CGTalk forum...read
download the free application here
here is the work flow how I bring the ivy into EI
1. model a building, in my case I model in silo, after finish model, I tessellate the model into Tris (Ivy modeler will convert any quad to tris, but it will cause flip normal problem) add in texture which is optional, than export to obj.
2. import the obj model into IvyGenerator, (read the 'readme' file for view control) double click on the on the building which of desire... for the Ivy growing point, than click on the grow button to see how the little thing "explode" click on the grow button to stop, than click the build button to build the ivy, after that export the ivy to obj (UV will generate by itself).
3. I notice that IvyGenerator will create 3 groups, 2 different leaf, and 1 branch, but when EI import the obj...or via transporter, it will merge the 3 groups into 1, and UV data will lost when save into .fac, sadly we pc user didn't have O2F, so I bring the Ivy to blender to save it separately in to 3 different files(3 groups) than import to EI.
4. I think there is some axis flip when import to EI, but that is not a huge problem, and IvyGenerator do come with some texture, just use it... :)
the render will take some time, the image above take about 20 minutes to render with my amd3800 but using 1 core (1280x1024) and RAM plays quite an important rule in generate ivy, don't push it too hard...
