Hey! Just a note about the Pyro Shader. Since the release of Houdini 20.0. Karma has gone gold, this means that it is production ready. As such, some nodes have changed. The XPU Pyro Preview is now accessed within a Karma Subnet. Alternatively, you can use the new Karma Pyro Shader node. It has the same settings but is built on a MaterialX Framework.
Thank you so much for this tutorial! I do have a question and I was wondering if you could help. I was not able to find a pyro shader that would work like it does in your tutorial. I spent several hours trying to noodle out what I did wrong. I'm going to try to copy my work onto Houdini 19 and use the XPU Pyro Preview. But I should ask, what exact Karma set node did you use? I tried taking a Karma Pyro Shader subnode from within the other Karma node sets like Karma Pyro Material and such. It wasn't working like you showed.
Thanks! Still not one-to-one however. At least not w XPU. Not in H20.5 either. In the scatter folder of the (new) "Karma Pyro Shader", by default when you observe the scatter folder, and the signature is set to "Color", there's no control ramp as one would prefer to have a one-to-one match with the Pyro Bake. Hacking: If you tried to use a ramp by changing the signature to "Float", you see a ramp, but it goes very bad quickly. First off, no change in value to either the 'intensity' or the 'hot core' will function at all when using that ramp. (There's more, but too much typing) But if you stay with the signature to the default as "Color", it's decent, and the intensity and hot core works although not the same as the pyro bake volume for the 'hot core' parameter specifically - It's way too sensitive. To the multitude of 1000's. It works though. Just stay away from trying to get the ramp color to work in the scatter section of the new "Karma Pyro Shader".
Hi, thanks for this. Best explanation of pyro I've seen - I usually just do stuff because it's what I've seen in other tutorials, but now I understand more what various things do and why to do them.
Awesome! That was exactly my hopes for this series. When I was learning, I would do the same thing. I would make an effect from a tutorial, but I found that I didn't really understand why I was doing the things that I was doing. I'm really glad to hear that you're getting more value from this 😁✌️
Damn, I learned more in this video than in a 5-6 hours gnomon workshop pyro course. Just going through this series one lesson after the other, thx so much!
Check if the density attribute is present in the temperature noise attribute(middle click), if it is not there try just deleting and re-plugging the connector, this fixed it for me.
