Maya to Houdini, an alembic workflow in a short film project I used
It demonstrates some tips to use Alembic to transfer Maya scenes to Houdini. In the maya scene, we have character animation, some books (Maya rigid body), and a room. we transfer all of them to Houdini for shading, lighting and rendering purpose.If we consider naming and keeping objects hierarchy consistent in every animated shot then this workflow is very efficient for finalizing and rendering shots in Houdini. you will setup once and use the same setup for other shots. this transferring setup can be done even earlier than completing the animation or alongside the animation process by another person. #Maya #Houdiniwork #samankhorram.com
Houdini 16: Create a render of 17,800,000,000 Poly flowers in 3 minutes and 14 seconds!
For this test render I had 10 rose flower models, each flower 17600 to 17800 polygons. At the first by using a scatter-node I have 20k copies of these flowers on the field, near 360 million polygons, in IPR I get a very fast response, enough for lighting setup, and look development purpose. For final test render I increased the number of flowers from 20k to 1 million,(in the video it is reported 5x more by mistake, actually it is 50x more), so basically now we deal with 17 billion and 800 millions polygons in the scene to render. Final resolution Full-HD 1080, min/max samples=64/128. All these setups are enough to use all power of the GPU and VRAM. and amazingly it took only 3 minutes and 14 seconds. to render the entire scene. In another test which I hadn't chance to capture, with Global Illumination turned on for both primary and secondary rays it took near 6 minutes to render the entire scene. #Houdini #effect #samankhorram.com
full process of creating Dynamic and manual controllers for polygonal Hair, using Maya and Houdini
Covering a technique I am using to make polygonal hairs of a character have dynamic movement plus manual controllers and a blender to switch between these two systems. Basically I am taking these videos in most just to have a record for future reference and to not forget what methods I used. -------------------------------- In wire deformer command add -dds (dropofDistance) to a higher value like 100,..when character goes way too far from origin wire deformer behaves strangler..it helps for that case. however at any points you can select all wires modifiers and change that parameter. ------------------------------------- #Houdini #Maya #Hair #Dynamic #polyHair
Houdini: I used python to randomize trees variation in this setup.
An example of using python to randomize some parameters. I needed to quickly apply some tone and value variations to trees' color distributed on a land so using python to directly change those parameters in a random fashion. #houdini #random #python
