![]() ![]() It’s not pressing a button and running a simulation, there are choices and craft that is art. ![]() The FX team uses the same artistry and physics as masters of the past. If you want to pull your hair out, spend a day weighting a character and finessing deformations. You won’t see pictures of a rigger standing over a machined armature, but they do the exact same thing to exacting standards. It’s a tough demanding job that is often overlooked. They make sure each pixel of the model moves according to each point of the digital armature. They meticulously build a rig in the sculpture. We even have a team of armature builders called rigging. The goal of most digital sculpting tools is to get as close to real-world sculpting as possible. In fact, a lot of digital sculptors work in clay on their off time. They understand form, anatomy, and 3D space just like artists that work in clay. Our puppets are modeled by master sculptors. Yes, every frame matters, and every frame is scrutinized. We sculpt the characters, we add an armature, and we animate them frame by frame. We build the puppets and animate them in the same manner as the masters. You know, that forty-year-old technology that ruins everything it touches.ĬGI is a tool and not a dirty word or cheating.ĬGI and VFX artists are the descendants of Willis O’Brian and Ray Harryhausen. Here we go again with the marketing of Oppenheimer having none of that filthy CGI.ĬGI that has been around since 1985. How not to suck at Python / SideFX Houdini #sidefx #houdini #python #scripting #vfx #cg #learning )ĭropping that out there in case this is a skill you are curious to grow. (As demonstrated in my latest tutorial about Solaris : )Īlso note that the scripting phase of this tool comes as a practice session in "part 3- A10" if you really want to know how to script it yourself. The part1 (1h of content) about python theory/fundamentals is completely free and also comes with a tool that will allow you to convert houdini's PrincipledShaders to MaterialX. It is still a work in progress but more than 8h of content is already available ! Detailing the plan of released content on this gumroad page (may release a trailer at some point) : things will get more advanced as we dive into the different parts of the course. I am going through practical examples to get comfortable with scripting and be able to create simple but useful script as a start. Trying to explain things from the very fundamental python knowledge (syntax, data structures, function, class etc.) and summing up years of experience I have with python scripting. thanks very much for providing the scene, sorry I could not be of more help.One thing I have been actively working on this year in my free time is a complete python course oriented for artists and/or technical directors using #Sidefx #Houdini. So again no quick fix sorry, but we do have this kind of thing on our radar. It's the reason I think Arnold looks like it has less noise in this refraction-heavy scene. XPU does not support this yet, but we have plans to support something like it in future versions. This is a fancy name for adaptive sampling. 3) KarmaCPU supports a feature called "automatic convergence mode". So in the next version of Houdini, and with an ADA Nvidia GPU, we can expect refraction scenes to run much faster. Its called "shader execution reordering". We don't have a quick fix for that, but NVidia's latest GPUs now have special hardware to address it. The high level of refraction bounces (ie 10) means there will be a lot of a thing called "divergence". Image Not Found This indicates that the GPU is not working as fast as it could be on your scene. thanks very much for providing the scene, sorry I could not be of more help. ![]() Normally I get something like Optix=97% CPU=3% (I have a crappy CPU) This indicates that the GPU is not working as fast as it could be on your scene. 2) I noticed the level between GPU and CPU was fairly low. 1) Sadly the new feature "direct refraction subset" didn't do anything to improve the glass rendering. ![]()
