Hi, For a school project I need to create a shot where the camera starts inside an ocean and slowly goes out (vertical travelling). That means at one point the camera sees both the inside and the surface of the water. I'm a beginner in Houdini and the schedule for the project is kinda tight. I was wondering if you could point me towards the good direction to achieve this effect? Should I use particles or is there a simpler way? Thanks in advance for your help!

Thanks for your help guys. I've been trying to play with the solver but it's still a little complicated for me to have something entirely opaque for the user (this is a class project and the teacher wants it to be super user-friendly). I'll keep trying to use a solver but I was wondering about something: is it a good way to do all the stuff inside a Python Module created in the Scripts tab? So that I can modify the grid using callbacks? Say I have 2 parameters: a grid initial state and an iteration parameter which is supposed to be animated. I could call a function to create the grid when the initial state parameter is modified and then use a callback on the iteration parameter to modify that grid? Or I could keep the core algorythm inside the Code tab and fetch the grid from the callbacks if it's possible?

Thank you very much, I'll try both solutions! Is it a proper way to store this kind of data using setUserData though? (just curiosity)

Hi there! I've been scripting in Maya for some years now and I decided to give Houdini a try but I still have some issues understanding how cooking works. I'm trying to implement my own cellular automata (a classical 3D Game of Life). The algorythm is pretty simple: my class first generates a virtual 3D grid which is made of livings cells (1) and dead cells (0). Then, at each iteration of a custom user input parameter, it analyses the current grid and does some work to modify it. But I have a hard time figuring how to do this. How can I have my script memorize its current state at each frame? For now the node just cooks entirely at each iteration, which is obviously pointless. Is there a way to execute only one method of my class? I thought about using a callback on the iteration parameter but I can't understand how it works in Houdini (I just made a "New Operator Type" and wrote my script inside the "Code" tab). Sorry if this sounds stupid, I'm still learning! And I couldn't find anything useful on Google.. Thanks in advance for your help!

Hello world! I'm working on a school project which consists in a gun bullet going through a robot helmet. The modelling and animation has been made in Maya and exported as an alembic. I imported this alembic into Houdini and separated each object of the scene with the Pick option. I added a Scatter node and a Voronoi node on the part of the helmet I want to break. Then I did all the RBD stuff and the destruction works fine except I have a very annoying problem: the shatters of the helmet are too visible. Some screenshots to help you understand: Frame 1 (notice the shatters on the opposite side) Frame 34 (after impact) I'm a noob on Houdini so I might need precise explanations! I've been stuck on this for days and I'm getting desesperate... Thanks in advance for your help!
