  1. Can I create or import a rectangular heightfield and export it as a rectangle not a square?
  2. When I use heightfield output I get colour images. Heightfield images are greyscale values (white high, black low, greys in between). But why do I get coloured images when I export a png. How do I get the full terrain, because for now I only parts (height, sediment…) spread in colour channels, where is full the terrain in greyscale? like the whole thing?
  3. Thanks, i meant the colour image. Heightfields are greyscale, why colour?
  4. It is solved, thanks again to both of you. I just would like to know what do people do with the exr's? I use the obj for clarisse, the png/tif for Vue/Terragen, but the colourful exr, what use does it have? am I missing something?
  5. Ok these are the parameters. IT WORKS. MANY THANKS to both of you.
  6. Does Houdini, yes or no, export the full terrain? I think this maybe the paramount difference between Houdini and [WM, Vue, Terragen...] Because I have seen the sidefx video on H17 terrains in detail, and I've seen that story of red blue green... and he hasn't given me the impression Houdini can export an image of the full terrain. So is it only in pieces? and how do I bring these pieces together? Why wouldn't Houdini have the full terrain exported?
  7. Tried to export a heightfield of a terrain in greyscale using cop2net and sop import but I get individual elements (height, water, debris, sediment...). 1. How do I get the full terrain out of it? 2. How do I even get these individual elements out? You've guessed it, I'm new to Houdini.
  8. I'm just trying to get this: https://www.google.nl/search?q=heightfield&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiaj8HksYvfAhXC2aQKHdVzDbEQ_AUIDigB&biw=1920&bih=979 one image in png or tif format that has the terrain, not pieces of the terrain. I know how to export an exr but I do not know what do with it, the exr is in colours. The heightfield is greyscale. I was born in World Machine, In Vue, in Terragen, I've never seen a colourful heightfield before the Houdini exr. Any help is truly appreciated.
  9. Thank you I managed to get 10% of progress and changed slightly the question. I did set planes from sop, I now can see the individual elements but I have no clue how to get them out, and how to get the full terrain heightfield, like the combined heightfield (which I can't see anywhere)? Years in World Machine, I need one file with the full heightfield to import in world machine or vue or terragen...
  10. Any idea how Boolean sop fits with the new rbdmaterialfracture node in Houdini 17?
  11. How do I use boolean fracturing in Houdini 17? is it already part of th enew rbdmaterialfracture? or is it still the separate boolean node, if still the sepaate boolean node, how to fit it in the newwork with the rbdmaterialfracture?
  12. xyz problem for imported fbx

    Many thanks, it works.
  13. Imported an fbx (attached) and i get the wrong behaviour of the dopnetwork with the xyz, gravity pushes the geometry to the side. Here is a visual description of the problem: any idea what the problem, how to fix it now, and how to avoid it in the future? Hut_fbx.FBX
  14. xyz problem for imported fbx

    2nd example Houdini xyz axis issue for imported fbx individual objects, I attach the second fbx as well, any idea what this is due to? Cyprys_House.fbx
  15. xyz problem for imported fbx

    Both were already there (Y up in settings, and convert to y-up in import), any idea what else could be the problem? the model was made in 3ds Max (2013) I attach all formats available: Hut_2013.max Hut_fbx.FBX Hut_obj.obj
  16. Hi, I have imported a model, applied voronoi fracture and some weird blue faces started showing up, I have made a short video showing the problem: https://www.youtube.com/edit?o=U&ar=1&video_id=bWiPswILZ0s any idea what these are? is it an issue at the modeling stage? normals?...
  17. Many thanks, does it mean that when modeling I should avoid "paper thin" and make sure everything has some dept? do you have some checklist to make sure the model is ready for destruction? I will use existing models, or make them, but in both cases I need to end up with something I can use. And for this current building model, do I just need to add dept to the paper thin parts, or is there more to worry about? because the chimney is not paper thin, yet it has the same problem.
  18. Paul, grateful if you could point me to the exact video you have in my about rbd preparation.
  19. Here is the fbx: https://wetransfer.com/downloads/253a5978e9bc8ff18d6b0f725f9349d020181026214450/ad09a91e71ea30a312abc3cf0aa17cad20181026214450/5fe3e3 thanks
  20. Thank you, I have do it by sub-element and it is still there actually I can see it clearer, I made another video: Any idea what there are?
  21. Any idea how I can add procedurally a brick wall structure to this circular watchtower?
  22. I run a pyro simulation (flames), using Houdini 16 non commercial, cached the sim (120 frames) using the import_pyrofields node (save to file->save to disk). I can see the cache in the hard disk 115MB file. But when I try to play in the sim after clicking load from disk, I hear a weird noise (this happened on two different days, the noise has to do playing the simulation), and the sim is completely frozen on the last frame I had played. Even if I go back to frame 1 you would see exactly what in the picture. Any idea what I may be doing wrong? After closing and reopening the file, I no longer hear the noise but the simulation is still frozen on the picture you see no matter what frame I move to.
  23. Any tutorials on animal fur?

    Hi, I have seen this lion fur in vimeo and would really like to know how to do something similar,how to achieve that level. There is a tutorial from cmiVFX with a lion as well but you will see the huge difference in result, I need something of this level: Thank you
  24. HI, How do I make fur in houdini 15.5 follow the direction of normals? I know how to do it in earlier versions but Houdini 15.5 has locked the node where it used to be added. Any idea? Thank you
