maya tip: passing on deformed particle and geomtrie

nonlinear deformers or scuplting on geo/partilces are great to tweak your sims. but it will not written into the cache file. the deformation gets always added on top of the cache. this is little bumpy, example: if wanna use the deformed nParticle to emitt into a fluids container.
in this case, you can use the new node editor to plug the outGeometry of the deformer into you depending geo/nodes like the fluids emitters. easy !

Maya playblast tool2

here is an improved version of the playblast script. Jean Denis pointed out the playblasting of more cameras is sequential and parallel. (thanks for that!) which would extreme slow in heavy scene with complex characters or large cache file. the new version of the script capture all cameras on each frame at the same time.  this way, maya have evaluate once on each frame and not do extra evaluation for each camera.  this way you can playblast simulations with different camera without caching.

i am using the active viewport for each camera to keep resolution constant. (and it avoid maya viewport issues).

* just made a little update to free maya after player is showing up

** another update: i added 2 more botton’s for houdini “mplay” tool. if you have houdini installed (even the demo version) it will bring up a mplay app and play until 4 cameras simultaneity in one window. (row or quas view)
tip: with shortcut “s” you link all view together and zoom synchronously

*** you use rv tile option (menu tools–>tile) to view all cameras side by side. i set it to default in the script

**** bugfix with timerange

new old waterfall designer tool

i had time to optimize my rig for old project:
this is a quick demo of realtime preview of my waterfall rig. the volume represents the implicitly volume rendering in renderman. i used couds shape to show in maya opengl the size and opacity of the implicit volume (renderman).

here example of my expressions setup for faking air pressure:

this is a screen of my adjustable volume emitter for my waterfall rig. i can fit the emitter to edge of the rocks and adjust the amount of water on each position with a ramp:
i hope i can post a video with all “water-structure” feature of my rig.

fire demon testshot

here quick testshot with the fire demon… to see how it works in production… still there are same bugs in rig to fix and the character needs a lot of fine tunning and i have working on look… the background was created with my own particle tools in maya which i build a couple weeks ago…
