  1. Hi, I'm running into a small problem trying to automate a Daily Tool. Basically I want to be able to get the BBox of my asset to transform them accordingly next to each other for presentation. Only Problem is when I query the Bbox_size or min,max,etc... using the Vex functions(usd_getbbox_size) houdini returns values that are huge (bboxSize = {-6.80565e+38,-6.80565e+38,-6.80565e+38}). Which makes it basically unusable. I don't know wether it's a bug Or I'm using it wrong. Thank you very much in advance! Antonino Here is my vex snippet: //=========== Parameters =============// string parentPath = usd_parentpath(0, @primpath); //----------- String Path Par string wildCardAsset = "/cube1"; //----------- Setting Bbox Par vector bbox_size = usd_getbbox_size(0,wildCardAsset,"Render"); printf("bboxSize = %g",bbox_size); usd_getbboxsize.hipnc
  2. Hey guys, Got an issue that's driving me crazy. I have a scene on my machine, that looks in a certain size, but when I try to send to an online farm or client machine, seems that the size/scale changed. My scene: When I send to the client / farm they see this: I got an fbx camera, I thought it was that, so I tried to using an alembic cam instead, same issue. I also tried converting the scaled geo (0.01) to 1, and issue is still there, not sure what can be causing this, if anybody got a idea of what can I try, will be super appreciated. Thanks
  3. Hi, I recently decided to recreate an old Maya project in Houdini. For that I had to export animated mesh from M to H so I used alembic. The 960f was 119Mb I did some modifications and tried exporting it as bgeo but it exploded to 106Gb so I tried abc which turned out to be 35Gb. And yes i added some attributes, subdivided few things and stuff, but it still seemed too much for the changes I made so I decided to explore. I exported animated abc from M (2019) of just 11f (step 0.25f) and that was 94Mb. I opened the abc in H with basic alembic node (default H18 settings) and export that with rop_alembic_output node straight from the alembic read node, with the same frame range & step. I've tried different formats (HDF5 and Ogawa (used by Maya) ) and settings here but all had pretty much the same size results of 1.5Gb. I didn't find any settings that would relay to compression or anything like that. Is it the same for you guys too? Does anyone have an explanation of this and perhaps a solution/idea how to reduce the abc size from H? Thanks Martin --------- Houdini 18.0.349 Maya 2019
  4. Cannot figure out how to decreases the fontsize in the helpbrowser. In the new sectio under preferences isnt a seperate entry for the helpbrowser. Also I know to do it manually with ctrl-/+. Is this the once way or anywhere else to fix it? Thanks in advance and a good day...
  5. Distribute by size

    Hello, I've got 3 boxes first is 15x20, second 20x20, and third 30x30. I want to distribute them in one direction in right orded but also to have even spaces between them. Anybody ecnountered similiar problem?
  6. Hi All! Are there any ways to optimise/reduce the file size of Houdini caches. I'm caching a (very small) FLIP fluid sim with a 'File Cache' Node at the moment and each frame is about 100MB. Multiply by 500 frames and that's a BIG cache! - not to mention the time its taking! I am sure it shouldn't be this large considering this is only a very small fluid sim so any tips would be great! I know a lot of people have this issue with sims so hopefully kind people can help us out! Thanks in advance!
  7. Real life lava simulation

    Hey Everybody, Im currently trying to create a lava simulation in real world scale. Im struggling with the surface as well with the simulation. Here are some of the issues that im facing: A surface that is very rough and there are some planes floating in the air Once the partials are hitting the ground it looks like it is loses density. If somebody could give me a direction or advice it would be much appreciated.
  8. Hi there Odforce! I had a small question which I hope someone will know the answer to! When i'm in the COP context, and I create a text node, how can I then get the actual width of the text? As you can see in the top part of the image, there is quite a lot of black padding around the word "Layer". When I drag the text outside of the actual canvas, you can see the blue rectangle that represents the actual size of the word. Is there any way I can query the size of that blue rectangle? Some more background on what I'm trying to achieve: I would like to move and resize the text to a specific location within a canvas. The text however, isn't predefined, so I would need to know the actual size and position of the text without manually having to override the size to minimize the background behind the letters. Thank you all for your time!
  9. Hi folks, my pipeline is Maya > Houdini> Maya I am a bit confused about scene scale. Please help me! Thanks in advance. These question are bogging me down:: 1. How much percent should I scale my objects in Maya to simulate properly in Houdini space? 2. If a real building is lets assume 260 meter high then what should be uniform size of it in maya and in houdini? 3. If I want to make some ocean sim what should be the size of the ship and the tank? 4. How can I understand this facts? Please give me some book/reference/tut if you can. Thanks for your reply!
  10. Dear Houdini Community, I've been trying to figure parameters of curl noise for my parameters and I've been stuck for quite a while... My object moves fast from left to right and emits particles behind. I used curl noise to create curls, but I can't make the curls bigger. They should quickly fly out of the object and then curl and disperse in the air. I am attaching my sketch which is easier to understand. Any hint appreciated. Have a nice weekend :} ~ashe bigger curl noise.tar.gz
