    A nice comparison of my modeling ability from 2 years ago to now.

    making a whole head with dreadlocks with dynamic ik chains will most likely result in frustration. in my experience you will never be able to get rid of the jittering dynamic ik chains produce on collision. i'd rather suggest doing it with actual hair. match your hair and guide count (you can simply set hair "as guides"), in the hairs generate tab you can either set it to generate splines (which you can then also sweep) or generate geometry directly... hair is much more easy to control and also much more versatile in its behaviour than ik dynamics are.

    I like both techniques and wonder why they couldn't be combined. While the Lester Banks video was easy to follow (as well as just brilliant) the first one minute tutorial required you to be super quick with the pause button to unpack all the steps. To help, here is what I as able to discern from multiple views in the first video: Tree Deformation (first video): 1) Set up a spline that matches the main trunk and subdivide it appropriately. 2) Set up a hair object converted from that spline 3) Link that hair object to some planar object (a disk in this video) placed at the base of the tree. 4) Set the hair object to generate squares --- I would imagine that this step somehow allows the geometry of the tree to be linked to the hair object performed in steps 6 and 7. Not sure. 5) Select the hair object and go to the simulate tab in the C4D main menu and select "Set roots". Now because the planar object was linked to the hair object in Step 3, that planar object now becomes the "root" of the hair object. Again, not sure. 6) Bring in a mesh deformer and make it a child of the parent tree object. 7) Drag the hair object into the object window of the mesh deformer. Set the external mode to "surface" and press initialize. 8) Go to the hair object's Dynamic's tab and set Rest Hold to 50% 9) You now have the tree model to be impacted by hair dynamics. Grab the planar object created in Step 3 and the tree will react appropriately. Add wind and the tree bends (but the leaves do not move -- for this go to the second tutorial. At this point, you can do some pretty neat things with the tree that even plugins like Forester cannot do. While Forester can simulate wind blowing the leaves and branches around, physically moving the tree around has no dynamic impact on the tree. This technique allows you to simulate a tree being cut or knocked down. Or something big (like a truck) crashing into the tree. For those who are truly gifted with X-particles (which means "not me"), imagine using the multi-physics capabilities of X-Particles to impact the tree dynamics. Could particle Advection be used to the drive the base hair spline on those trees? Couple that with the X-Particles grain solver and could it be possible to have an avalanche tear through a forest pretty realistically? Or have the leaves on the tree generate static particles which are then advected by the fluid simulation of an explosion while the tree reacts dynamically. The effect I am thinking of would match those 1950 videos of nuclear bomb shock wave ripping through a winter forest in slow motion (as seen here at 18 seconds in) I feel that this can be done because X-particles is so well integrated with C4D --- but not sure. I would hope Mario Tran Phuc reads this thread and is challenged by the concept. If anyone could do it, it would be him. That guy never ceases to inspire. I also hope that full dynamic capability is added in Forester 2, but they are too busy with Rock Engine - a pretty cool landscape generator for C4D - so don't hold your breath. Dave

    I couldn't make up my mind about the flooring so here are two versions enjoy

    You are welcome. BTW, you can also set a collider object within the ik dynamic tab settings.

    To my eyes this is prettier than the textured and rendered result. Elegant economic flow...

    Cerbera! You are a topomaster! ... Look at those lines... one more it will be too much... one less it will be not enough! ... Great! ... ... João Marco

    You have really nice topology in your models! So Clean!
