    Pilot light sim

    Dear OD Forcers, I am attempting to make a pilot light for a kind of flamethrower for a shot I am doing. Upon Googling, someone said don't use Pyro, do it all in SOPS: but I went ahead and managed to get, I dunno(?), a half decent sim [there are other reasons I want a sim but that's another matter]. I want to render everything in XPU in Karma and looking at blowtorches for reference I see that what I need (am missing) is the kind of bright, variously coloured cones at the beginning of the flame. I am imagining I can get this with banded ramps in the fire part of the pyro shaders. However I am struggling. Any advice or tips? Also the XPU pyro preview node seems to not have a ramp in the fire part. Do I have to crack it open to fix this? Because I cannot see how. My .hip is attached. Thanks in advance for any help.

  3. Hi, I'm new to Solaris and Karma, but does Karma xpu allow embedded transparency from textures? I've run into an issue rendering textures with embedded transparency. My example is a tattered cloth texture, where the tatters and holes in the texture are rendering fine with Karma cpu, but not with xpu. I've tried a number of variations using the principled shader in combination with Mtlx tiledimage but to no avail. Again, this renders fine in Karma cpu, but could someone please outline the workflow for this in Karma xpu? Thank you!
  4. Thrilled to show a teaser of my future Houdini tutorial. Key topics: - Proceduralism: geometry and animation - Pyro: explosion with love - Karma XPU: pain and joy *99.9% done with Karma XPU Release on gumroad soon.
