  1. Setting Default Scene File

    Hey thanks for this info. It's not working still..... I saved a 123.py file in a newly created folder scripts with notepad. I pointed it to the template file that I put in my $HOME folder. It works when I type it in the python shell but not when I load houdini.
  2. Setting Default Scene File

    Hey there, So I have been looking around on various posts to try and find out how I take my template scene file and make so whenever I open a version of Houdini that template file is the one that opens. I know very little about scripting and I am not sure what I am meant to change in the 123.cmd file. Anyone ever done this and know how to set it up, please? Thanks
  3. Time offset Lukas Vojir

    Hey internet, SO watching this great presentation (bellow) and I noticed they had created a lot of their own tools. One in particular that I am trying to work out and build myself is the time offset tool (29:58). I have taken a screenshot. Can anyone work out how it's built? I am pretty new to building tools like this so any help would be really useful. Thanks Andy
  4. Flower Center??

    Thanks yader!, Great stuff. learnt alot here.
  5. Flower Center??

    Hey thanks for the link but not quite sure I understand what it is? I have the Phyllotaxis set up working but as you can see in the image below it doesn't really give the result I need. The points need to be dense in the middle but the scale needs to reflect that spatial distance. Thanks for your help
  6. Flower Center??

    So i understand how i use this but the issue I have is controlling the scale from the center out....
  7. Flower Center??

    thankyou these resources are great!
  8. Flower Center??

    Hey Houdini legends, I am trying to create the centre of this flower. I have created all the tint disc flowers but now need to clone them onto a radial hexagon grid sort of thing. I have made a sphere and managed to get a honeycomb grid with the divide sop but I need the polys to get larger towards the outside and the pscale to reflect the scale of the prim. Any Ideas?
  9. Constraints rigids and vellum

    Yes, but it would not be rigid? thanks Andy
  10. Hey, I have a brain scratcher that I need help with. I have animated a jacket with vellum using cloth constraints and then cached it out. Now I have the toggles and zipper to add I can use vellum as it doesn't do anything with hard bodies so how can I constraint them to the geo? Any help would be great! Thanks Andy
  11. Dynamic wool...

    Hey thanks for this! I will upload a hip file so you can see what I'm working with .
  12. Dynamic wool...

    Hi, So I have a complex problem that I can't get to the bottom of. I have created trails using volume curl fields. I want it to look like a ball of synthetic down/woollen filling. Now I want this to be dynamic so if it laded on the floor it would have volume but if I use vellum hair it just falls flat because it is just a bunch of curves. Any ideas ? Thanks Andy
  13. Scatter pscale changes every frame!

    Thank you so much anim! I'm learning a lot! I think i have worked out the problem tho. I basically am trying to delete points outside the FOV to make it run faster. The problem is that this seems to change the point number so it starts flashing all over the place. Any ideas of how I can trim point outside the FOV without changing the actual point data? Thanks Andy
  14. Scatter pscale changes every frame!

    okay thanks! So I need the particles to stick on the deforming geo but also for the values to stick to the particles i.e pscale. I used an attribute transfer from a held frame after the interpolate not sure it is working tho. thanks
  15. Hey, I have a very frustrating issue. I have an alembic that I have scattered points onto and managed to get them to stick in place. The problem is now the random values I have assigned to these points i.e pscale, change every frame. Does anyone have an idea how resolve this, please? Thanks Andy
