Now that we've got the formalities out of the way, I've been having a nightmare of a time matching Karma renders in the viewport / mplay. The ACES transform from ACEScg just never looked right, colours ended up too saturated.But I've cracked it for davinci resolve. Use EXR output:Houdini Settings:
Edit > OCIO Settings > ACEScg
(Setting this to acescct fucks up the viewport)Karma Render Settings
Image Output > AOVs > Component Level Output > Output Colorspace > ACEScctResolve Project Settings:
Pic-related + in the colour page, project nodes add an aces transform with the following settings:
- Input Transform: ACEScct - CSC
- Output Transform: sRGB
This will let you mess withe gamut compression and do post-srgb changesThis will exactly match what you see in houdini.

Does anyone have some good resources on how to shade and render pyro fire and smoke in solaris karma? I tried to make this shot but dont know how to make the fire at the end look like smoke instead of fire.

Does anyone know how the hell I can get points scattered as a volume on a deforming mesh to not jump around like crazy and change their point numbers? Time shifts and rest nodes aren't doing shit. I just want to use this running character as a pyro source and have the points stick in one spot- so I can drive a certain degree of the smokes velocity using their normal direction

Does anyone else feel like they're perpetually at 70% with everything they try with this software? At this point I get the basic jist of how to do most of the things I think of, but then I either hit some wall that brings all of the experimentation that came before it to a complete halt, or I just get stuck with a shit version of the thing I was imagining, that's everything I was trying to make it be, except it looks like shit.

Started looking into it because this tutorial implied it is a viable alternative to Russian3dScanner/faceform for transferring ripped game model heads onto daz/other generic template human body models.

That feeling when you get over the houdini gatekeeping by reading the documentation, but you still keep maya and blender in the toolbelt because they just work better for a lot of things and your entire output is going into a game engine anyways because film and tv are both utterly and completely dead.

What am I missing with updating textures in Houdini? It takes some finagling to get certain updates to appear, and sometimes it's recreating the import node entirely to get something to show.
I see there's an "update textures" button in Render up top, but that does nothing largely.

I'm supposed to reproduce these as an exercice. I'm having trouble with two thing on these
> 1st pic
How did he manage to keep the top of the extruded regions flat and valley like? I tried using a mountain noise on a primitive group (selected randomly which also doesn't give the same effect) but it doesn't work, it's extruded on the normals of each primitives which creates a mess of overlapping geometries?
> 2nd pic
Also after the polyextrude, how did he manage to divide the geometry to have cube like formations instead of only have the surface primitive being extruded.Don't spoil it too much for me, clues and directions are enough.Sorry if I don't use the correct words of if I'm too vague.

Tell me something. I learned the basics of Houdini, I know how to use VEX, I know about groups and attributes and most of the important nodes for modeling.
But something doesn't click in my mind about which VEX functions or the procedure I need to implement to do something I have in my mind. I lack knowledge about most of the VEX functions + I guess the IQ to come up with a solution by myself.Is it really an IQ problem or an experience one? What do I do? Spam tutorials? Again...
how retarded of an idea is it to jump into houdini with no prior artistic skills or knowledge of 3d or programming?
even at animation universities it seems to take them 5 years to develop the skillset required, and they do this stuff several hours a day.

fun little tip:
if you put a 3@transform matrix on your rbd geo before it goes into the sim, the solver will actually update the attribute for you
came in really handy for instancing back geo onto emitted objects where the emission source was not static
from several million polys down to a single packed geo instanced a few thousand times

I need some help on the following if anyone might have some ideas:
I'm trying to implement a procedural city tool. The catch is that I try to automate/procedural(ize if that even exists as a word) as much as I can for the following features (so far)
- A terrain generator
- An urban area generator
- Street/lots generatorMy issue is connecting the terrain to the urban area tool, as well as the urban area tool to the streets layout tool (tools = HDA's obviously).
My problem is how much control I lose over my streets layout. I'd like to have some verticality and explore in real time the changes I'll make whenever I feel like it.
So how can I do that?
I thought of either
- Just manage a ton of curves (pain in the ass)
- Feed it an image as an input (much looking like pic related) and create the curves from that (less of a pain in the ass but longer times to edit)But since I'm a total amateur, I feel like there might be another way?

I was hoping some Anons here could clarify because Google isn't helping much. But from what I understand, Houdini mostly uses the CPU for simulations, but can use the GPU for some as well. What kinds of simulations are faster and practical on a GPU compared to a CPU? Like yeah, CPU will always be more accurate, but if I can dramatically reduce the time spent simulating I'll take the minor hit to accuracy.

Question for you guys. I'm trying to access vertex groups created in Blender (and exported as an .abc) in Houdini. A quick google search said I should be able to find the vertex groups I created in Blender in any group drop-down menu in Houdini, but they're not there. I created this super basic statue with a vertex group on Suzanne's head (the monkey head), but as you can see in the group drop-down menu, the vertex group (which I named MonkeyHead in Blender) is not there.How can I access my vertex groups made in Blender in Houdini?
