  1. I have a node called wireframe, which takes RGBA values for a wire colour (Parameters: wireColourR, wireColourG etc) If i wanted to wire in the Cd values from points on the geometry, is there a way of adding this Wire Colour parameter as an input on the WireFrame node? Thanks for the advice
  2. Alpha channel settings for EXR into After Effects

    Yeh Mplay displays a similar alpha, but with all channels on it creates an image like in my post above, whereas AE/ Prem do not, the image has far less detail. Maybe this could also be a Redshift thing.. I dont know yet. By changing my AE settings to the following I can get the image to look similar, but whatever I export still seems to have the same alpha issue once in Premiere. Perhaps this is starting to be more of an issue for an Adobe forum, but I just thought there would be some people here who have a simple answer, given this must be a very common workflow.
  3. I'm having trouble deciphering the correct workflow for importing Houdinis EXRs into AE and then out for edit in Prem Pro (EXRs are exported from Houdini/Redshift with default settings). It seems like the alpha channels are very weak, and leaving nearly my whole image transparent. Does anyone have a tried and tested method which they could share for bringing Houdinis EXRs into and out of AE, for an export into a format like ProRes 444+alpha? I've had a look at a few posts online and played around for hours with countless colour management and alpha premult settings within AE but feel like I'm banging my head against a wall. Ive attached the EXR and a Mplay vs Prem comparison. Thanks for any advice ExampleEXR.exr
  4. Very useful attribute when doing anything that involves rendering particles or copied geo. I use it endlessly. For example, it can uniformly change the size of your particles, by creating a wrangle and adding @pscale = "insert float value here" And beyond that add noises etc to the pscale value in VOPs for interesting effects. Remember as well that when copying geo to points the pscale attribute will also affect the size of copied geo if "Copy Point Attributes" is selected in your Copy to Points SOP.
  5. Reference geometry filename in export filename

    Thats great, thanks for your help, much appreciated
  6. This is probably a fairly simple one.. I have a geo sequence which I want to convert and export into a different format. I would like the filenames to remain the same as the original geo, (apart from the new filetype suffix). How would I reference the name of each frame of the original geo sequence? Thanks for the help
  7. Hi. I have an interesting problem I've been trying to solve for the last few days but still haven't managed to find a good solution. I have a sequence of geo which has been captured with a depth sensor. One of the issues with the sequence is that the point numbers change positions every frame. Whilst there is a rough order to the point numbering per frame, its not very consistent. I'm wondering if there would be a way to homogenise the layout of the point numbers by reordering, or to somehow re-mesh the geometry sequence to create a new version with more of an ordered structure? I've attached a short bgeo sequence as a sample if anybody would be interested in having a look. Thanks for any advice VolumetricTest.rar
  8. Script to resume crashed render

    Thanks for everybodys input. Ive ended up going with the free version of Royal Render, and it has been relatively easy and effective to setup on a single machine, and I have very minimal networking skills. For whatever reason, I was finding that the rrSerivce was not resuming my renders on a system restart, so I placed the win__rrClient.bat into the Windows startup directory to force it to start.
  9. Script to resume crashed render

    Thanks. Do you know if the free version of Deadline has this functionality?
  10. It's quite common that Ill set off a render at night only to find out in the morning that it has crashed at some point a short way through. Generally, if I simply restart houdini and render from where it got up to, it will continue without problem. Not sure why this happens, but it does mean over night renders are often a gamble. What I'm wondering is, would it be possible to have some kind of script which detects a crash, reboots houdini with the working project and takes off from the last rendered frame? Would such an idea even be possible?
  11. Convert tris to quads

    As a side note to this which may help someone in the future: if youre wanting to render a wireframe quad look (which is what I was after), using Redshift selecting Rendering an object as Strands will automatically render the wire frame as quads.
  12. Convert tris to quads

    Cool, thanks for the help
  13. Convert tris to quads

    Hi, Im wanting to render a wireframe look of a scan captured asset, but Id prefer to lose all the diagonals and have it in quads.. is there a simple way to convert tris to quads in Houdini 17.5, I cant seem to find it? Thanks
  14. Redshift Proxy Workflow in Houdini

    So does that make the above instruction now irrelevant?
  15. Flickering colours in slow Coloured Smoke

    Ha..! I will have more of a look tonight as well. Very easy to replicate the problem, just lay down a coloured smoke (via shelf), and gas upres it (also via shelf). Youll see straight away that the upres smoke is black. -J
