  1. Hi. Yes I have tried that. Does not seem to do it.
  2. Hi there. I have a bunch of particles flouting around a forest scene. I am trying to only render out the particles. But the trees seems to always show up in the normal and Zdepth passes. I would like to know how I can render the particles such that they are masked out by the trees but not to then have those tree rendered in any of my passes. Cheers.
  3. Hello there. I am new to houdini and have zero shader building experience. I am trying to build a shader that gives the look of ash on particles. I have a battle field scene with smoke and the likes flowing across it. So the particles needs to have random noise on it. This noise needs to effect the alpha as well. Then needs to fade off as it reaches the edge of the sphere relative to the camera. Cheers
  4. Great thank you
  5. Ok i have found the delay load procedural node. Assign that shader to my object and that seems to speed up the exporting HUGELY! How ever I now dont know how to add the shader I want to my particles because the "material" tab already has a shader on it. Any thoughts?
  6. Hi there. I have a scene with several cached particle systems. When I send the scene off to the farm it creates IFDs. It seems to output the entire cached frame into the IFD. Making it take allot longer. Now my understanding was that checking the "delay load geometry" box in the "load from file" would make the IFD write out just a link to the cached geometry. This does not seem to happen. What am I missing? Cheers

  8. Hello. I am busy setting up the controls on a subnet. There are two things I would like to be able to setup but I cant seem to find the help for it. 1 A ramp. I have a few ramps in my scene and I would like to have them in a custom interbface. I am just not sure what I need to link up and where. 2 Visibility toggle. I would like to be able to change the visibility flag in my setup. So when I press a button on my interface I can then see my setup at different stages. For example. See the points scattered on my object before I copy things to them. So I can better see what they are doing. Cheers
  9. Good day. I am trying to make a space cloud. I was thinking of using particles for this. I have a simulation running which is not looking to bad for a starting point. But I have run into a few issues. Firstly I would like to group particles in the cloud and assign different shaders to them. This seems to not work for me. I assume that all I need to do is add a material node. Add in the groups and point them to a shader. Cleary I must be missing something. Works when I do it to a box. Secondly I would like some of the particles to light up the surrounding particles. This seems to not work. It works when I assign the same shader to a sphere and put it in the particles. But the same shader on the particles does not work. Any ideas? Also if someone has any general advice about doing this, hints and tips to make it look awesome. That would also be helpful. CHeers
  10. Yes I see them as well. They just dont seem to do anything. I connect a vector to a vertex texture and I get nothing. This is why I dont know if I am missing something. Maybe the error is somewhere else. Like me exporting it from houdini? Any thoughts?
  11. Thanx Peon. I will have a look again. Might be something I missed. There are so many dam data nodes in Maya. Would be easy to miss. But I think I gave it a good once over. I dont think I missed anything. Maybe the problem is somewhere else? Multi points of failure makes it hard to find where the problem is.
  12. HI there. I have a sphere that I put a bunch of random attributes on to. I promote these attributes to vertex. I alembiced it out. On the Maya side I can find the color on the vertex. IT is under "colorSet[0]" But I cant seem to find the rest of them. I dont know if my problem is on the houdini side or maya side. If someone could please talk me through it. Or point me to a good tut that covers it. Oddly enough that seems to be a hard topic to find a good explanation on. Cheers
  13. Wow great replay. I am so going to try this out. Thank you so much man !
  14. Sorry man. I dont know what "template points" mean. Still new.
  15. Hi there. I have a sphere. I have put several points on there with scatter points. I have copy stamped a sphere onto those points. I would like to have those sphere change in scale on rare occasion. Kind of like vibrating but in scale. How can I go about setting up a "vibrating" animation and then have that animation randomly execute on a random sphere from time to time? If I am not mistaken I need to use copy in chops. But I cant seem to find a good tutorial on this. Any idea where I can find one. Unless I am heading in the wrong direction on this. Cheers
