  1. Pyro Resolution Fix

    Hi, I have setup a pyro, its resolution seems nice and crisp but as the bounding box expands the resolution seems to fall down and everything looks voxelized. How to setup the pyro in such a way that it maintains a certain resolution according to the size of the bounding box. I have attached a link of the pyro video, you can clearly see the fire becoming lowres as the boundingbox expands. Please let me know how to fix it.

  5. Pyro sim eats all my RAM even when cache in dop is off

    Hi, I have attached my file, please can you look into the file and help me with this ram issue?? explosion_v01.hip
  6. Hi, Whenever I run a pyro cache, that is, I import the pyro fields and attach a fileCache node and write out the cache. The simulation eats up all my RAM as soon as the caching starts and then almost freezes my system. I always check off the cache sim option in DOP node that disables saving cache in RAM, but even then my RAM quickly gets filled up. I have created a basic pyro explosion not very large scale and I have 32 GB RAM. Is there any way to control or limit how much RAM Houdini uses for simulation? Like say, use 28 GB RAM and no more or flush previous cache from RAM automatically. Thanks

  11. Fit range confusion

    Hi, I was watching a tutorial and the instructor used negative value in fit range node's source min parameter and then he said that as there is a negative value in source min so he will have to flip the the destination min to 1 and destination max to 0. I don't know why we must do that. Can anybody please explain the math behind this? Fit Range Node's details: source min = -5, source max = 1, destination min = 1, destination max = 0. in the value parameter he takes some random attribute that ranges from -5 to 5 based on the point numbers.

  13. Add Name Attribute Via Python

    Wow, Thanks it works like charm. Hey can you please help me with python for houdini. Because the documentation for python in Houdini is very wierd. I cannot get enough examples and all the functions are very hard to find. So can you point me to some documentation elsewhere or tutorial? Or can you please tell me how to follow the documentation because I always feel lost in it. Like finding some examples or some function name, etc.
  14. Add Name Attribute Via Python

    Hi, How to add a name attribute to each point in a selected geometry via the python sop? Suppose I have a box with 4 points and I want each point to be named as piece0, piece1 and so on where the number is its point number. I have written a code, it adds the attribute to the spreadsheet but is unable to add the value. The value is added only when it is not a string. Please Help. The code that I tried: node = hou.pwd() geo = node.geometry() geo.addAttrib(hou.attribType.Point, "name", "piece") Please also add how to add the respective point numbers to the string piece. Thanks
  15. Copy random fracture pieces over points via copy sop

    Hi, Thanks a lot for your help. It even works with the delete sop but I am really confused, because this expression works perfectly when I put it in group parameter of delete sop but when I put it in pattern parameter then the expression copies one single piece of geo onto every points. Why is that? How does it works in group parameter? Can you please explain?
