  1. hi guys I'm doing burning effect so I need a sequence alpha map. I made a procedurally burning area and alpha. So I could get alpha area on uv. Then, I wanna render the sequence uv map like I see on the uv viewport because wanna edit this uv texture in nuke. How can I render this uv map? plus, it's UDIM.
  2. how can I render with IFD?

    Here's my hip file. thanks! dust_ifd_test.hip
  3. I need to reduce render time for volume so, I tried to use make ifd format. then, how can I render this IFD? the only thing I can is just to click render to MPlay. I wanna render to disk.
  4. render EXR colorspace

    Thanks haggy. it's easier to work than change colorspace in nuke. I was a little bit confused. thanks.
  5. maya hair matte problem

    Hi guys I need hair matte for the rendering, but the hair work was done in maya X-gen. Can I import the hair into houdini?
  6. render EXR colorspace

    thank you. but I think it was not linear of the default color space when I imported render image into nuke. it was gamma 1.8 at default. so, it was same look on mantra render view and nuke. anyway, thanks for your explanation.
  7. render EXR colorspace

    Hi, I used to check some colors of my works with mantra render view, then rendered. But when I imported the render images into nuke, the color information was different on view. So, I have to change colorspace to sRGB before compositing because it's similar to houdini render view. Why does the image render on linear colorspace?
  8. a question for making custom normal on Point

    Thank you, f1480187!!!! using dot product then find max value, it would be so useful for me to do procedural animation. Thanks again
  9. a question for making custom normal on Point

    Yes. you're right f1480187. When I applied it to my real geometry, it was not correct. So, I just tried to use Sort node. I sorted points using 'Along Vector' {0, -1, 0}, then I made normal with vop ; I used subtract between position of ptnum and ptnum-1. It's not exactly correct, but it is pretty close to what I want, cuz I just needed velocity for popnet. Thank you for your advised f1480187!!
  10. a question for making custom normal on Point

    I tried to use Guide Tangent Space node so I make tangent attribute, then I cross product between my N and tangent, it works!! custom_N.hip
  11. a question for making custom normal on Point

    thanks fencer, but it doesn't work. I made a default N with Facet. then I want to make N which is head to down along edges.
  12. Hi guys. I was wondering how I make normal like this image below. there is a cloth surface, and i need to make custom normal direction have any idea? thanks.
  13. copy animation object to L-system

    hi guys. I want to make a growing plant animation with L-system. but I have a issue of input J and K. I'm gonna use animated-alembic cache for growing flower and some leaves. So, I tested simple L-system. I made key-animation object for input J and K. but I couldn't control the frame. any idea for me? Thx. l_system_copy_animation.hip
