  1. Hello, I'm having some issues rendering my pyro simulation in Redshift. For whatever reason the volume and the ground interact in a way that creates these solid bands of light (lower left quadrant of explosion) lingering in the volume. Both object render find on their own. I was hoping someone else has run into this issue. Thanks for any help on this!
  2. Using mattes in redshift?

    Perfect. Thank you!
  3. Using mattes in redshift?

    Hello, I'm trying to render out separate passes for different objects in my scene. In mantra I would just need to set the correct object and correct forced mattes for each mantra node and then could render them all at once. The force matte option in the redshift rop doesn't seem to work for me. The only way I've found to get mattes to work is to enable them in the redshift properties on the object nodes themselves. I'm hoping there's a way I can batch render these like in Mantra and not have to manually switch the matte options for each pass. Thanks for any help you all can give!
  4. Hi, I'm currently trying to render a scene in Redshift and I am getting some strange flickering reflections. I read on a forum that this might be able to be fixed by upping the anti-aliasing settings. I've been searching for a bit now, but can't seem to find where I would be able to alter the anti-aliasing setting in the redshift rop. Hope this doesn't end up to be just a huge oversight on my part. Thanks in advanced!
  5. New machine in light of the upcoming Ryzen processors.

    Thanks for the replies! It definitely seems that the TR processors would be the better choice if I want a build that I'll be able to expand later to fit all my needs. I worry a bit that if I were to make a TR build now I might be disappointed when the 3rd generation comes comes out. I probably shouldn't get a Ryzen processor simply because it will be out sooner, thought. Hopefully whichever TR motherboard I decide to get will be compatible with the 3rd generation Threadrippers once they're release. Thank again! Nick
  6. Hello, I'm looking to build a machine for Houdini, as powerful as I can, as soon as I can. I'm looking to invest a good deal of money in it and despite all my research in the last few weeks, I don't fully trust myself to spend a decent amount of money building a Houdini machine without asking some advice from some people with more than three weeks of hardware knowledge. Thanks for any help you can give me! I initially was going to make a threadripper build, since I at least know Houdini scales well with a higher numbers of cores. I'm hesitant to do this though since the new generation of Ryzen processors are coming out soon, and it's possible that the 16 core Ryzen processor may be competitive with if not outperform the 2nd generation Threadrippers. One worry I have though with the new Ryzen processors is that their motherboard seem to only have 4 memory slots, and not quite as many graphic card slots as the Threadripper motherboards. I know memory is very important for work in Houdini and that gpu rendering is often times a good solution for a home computer. Would the limitations of the new Ryzen motherboards make them a bad fit for high level Houdini work? I guess my other option would be to make a threadripper build and then hope that when the new generation of threadrippers come out that I would be able to slot them into my current motherboard (I would be willing to wait until September to upgrade to the 16 core ryzen, but I don't know if I could wait until the third generation threadrippers come out to have a decent computer). Again, thanks for any help. If you don't have any particular advice for my situation, I would love to just hear thoughts and opinions on the new lineup of processors from amd and just general hardware for Houdini advice. Cheers, Nick
  7. Saving changes to promoted wrangle snippet

    I figured out a way to do it. I just had to right click the parameter and make it the default. I don't know if there is a more efficient way to do this, but it should work for me.
  8. Issue with conditionals

    I'm trying to make an HDA to help me learning some scripting through Houdini. I got stuck at a point where I am trying to get certain rectangles to light up based on the position of some scattered spheres. I used if statements to make it work with one primitive sphere. Something like if the point is in this area light up. I'm wondering if there is a way to make it so that if any of the points are in any of the areas those areas light up. I'll attach the hip in case I wasn't clear with what I'm asking. Just look at it front view, and it's mouse_setup 2. Thanks for any help on this! Mouse_clip_Tests.hiplc
  9. Hello, I'm trying to create an HDA that can be used to learn scripting through Houdini. I wanted to be able to promote the wrangle snippet box to the interface of the HDA. It works fine except for when I make changes in the textbox on the tool and then try to save the node type. It does not save any of the changes I made. Thanks for any help on this! Cheers,
  10. Trying to learn Vex. Major differences from typical OOP?

    Thanks for clearing all that up. I think I'll just do the deepest dive I can into Vex. Tokero has already been the main resource keeping me afloat learning this stuff haha.
  11. I'm attempting to deepen my knowledge of vex and was recommended a book on programming using processing (Learning Processing, by Daniel Shiffman). For anyone with good knowledge of both Vex and another object oriented programming, are there any major concepts that will not translate over to vex. Like, is there a way to create classes in vex? Just trying to streamline my learning of this stuff so I can stop being merely a knowledge sponge around here. Thanks in advance for the help. Cheers,
  12. Not able to find houdini.env?

    That helped. Thank you!
  13. Hello, I'm trying to install the Octane plugin for Houdini 17.5, but am having trouble finding the houdini.env file. I'm pretty sure I'm looking in the right place (This PC\documents\Houdini17.5), but it's just not there. Is there something I have to do to initialize it or is it supposed to be there by default? Thanks a bunch for any help.
  14. Hello, I'm new to Houdini and fairly new to 3D modeling and FX fields as a whole. I'm wondering if have external texture maps like color maps, displacement maps, normal maps, etc, if I would be able to somehow apply these to a mesh in Houdini provided it has UV's. I searched a bit to find information on this , but all that I found had to do with created the texture maps within Houdini itself. Hope this isn't too simple of a question!
