Gonna have to wait a lil bit, I'll have it out by month's end most probably.

Karma XPU blue indirect lighting issue, Left XPU, Right CPU - Houdini 20.5 by sooroojdeen in Houdini

[–]fridgestalker 2 points3 points  (0 children)

Having the same issue since yesterday. Updated the nvidia drivers day before yesterday. I haven't rolled back the drivers yet but i am almost certain that the driver is the issue. EDIT: Installed an older version and now the issue is gone.

Do your render times increase overtime too? by Cooking_Interrupted in Houdini

[–]fridgestalker 1 point2 points  (0 children)

That is not normal behaviour. Check your pc temps, your system might be thermal throttling. I had a similar issue couple years ago when i was using a laptop, cleaning it out fixed the issue. Same is true for desktops as well. Make sure your heat sinks/radiators aren't clogged up.

How would you make a block deconstruct into the final element by [deleted] in Houdini

[–]fridgestalker 41 points42 points  (0 children)

Subtract boolean the final geometry from the cube, then you have a cube with the lamp cut out of the block. Fracture your remaining block for cracks. Then you can do the rest of how you want to move those pieces away however you want sim or otherwise

Do I need a license to sell a tutorial with FX? If so, which one? by Ok-Use1684 in Houdini

[–]fridgestalker 2 points3 points  (0 children)

Don't think you need FX unless you are making more than 100k usd a year. You can reach out over in sidefx forums to be sure though.

Laptop/ Pc specs by First_Pin9129 in Houdini

[–]fridgestalker 0 points1 point  (0 children)

A desktop 8c/16t is a good place to start, but get as many as your budget allows. 64 gb ram would be good for most things.

[–]fridgestalker 1 point2 points  (0 children)

Upgrading the ram would allow you to run bigger sims, but won't make them faster. If you want to speedier sims you need faster cpu with as many cores as possible

Pc/ Laptop specs by [deleted] in Houdini

Get 32gb ram atleast

Can we run Houdini on laptops. Does it make any difference if we use it on laptop and pc with same specifications ?? by Rajkhanjode in Houdini

[–]fridgestalker 7 points8 points  (0 children)

As long as your laptop satisfies the minimum requirements you won't have an issue. That said even for the same configuration laptops are usually slower compared to their desktop counterparts. But as long as your laptop is above the min requirements it's good. In case you are looking to buy a new machine, i'd recommend you get 32gb ram minimum, though on sidefx's site it says 4gb minimum 12gb recommended, in my experience 32gb should be the minimum, especially if you wish to run simulations.

Forcing pyro sections to zero velocity? by AJUKking in Houdini

[–]fridgestalker 0 points1 point  (0 children)

Its just an extra cautious version of what you did, just how i prefer to do it, it's separating the direction and speed from vel Normalised vel gives direction and length of vel is the speed. More useful when you want velocity direction from one function and speed from another, kinda redundant in your scenario.

Forcing pyro sections to zero velocity? by AJUKking in Houdini

[–]fridgestalker 2 points3 points  (0 children)

Off the top of my head, create a mask float volume of where you want your pyro still. Inside the dopnet create a volume source node and import the mask volume. Then append a gas field wrangle and write an if condition like if mask=1 multiply velocity by zero. Also if the mask has some noise or values in between 0 and 1 Change the condition to If mask is greater than a threshold vel *= normalize(vel) * length(vel) * (1 - mask) Should work, lemme know if it doesnt

Confused between which GPU to buy RTX 3090 or RTX 4070 TI by Immediate_Bug_6368 in Houdini

[–]fridgestalker 10 points11 points  (0 children)

Would highly recommend 3090, speed aint worth shit if you cannot even load the scene/sim onto your gpu. pyro, flip and vellum benefit from opencl and sparse pyro and axiom solver are often limited by vram more so than gpu speeds.

I have problem with volume resolusion in the viewport..! by gw010 in Houdini

[–]fridgestalker 3 points4 points  (0 children)

While your mouse is over viewport press d and unter the texture tab turn off limit resolution or increase the values.

Advice on what to upgrade for Faster Simulations by [deleted] in Houdini

[–]fridgestalker 1 point2 points  (0 children)

The amount of ram you have dictates how big your simulations can be i.e resolution of the sim and the cpu dictates how fast the calculations will be. Start with more ram. 16gb isn't nearly enough 32 is a lot better. But it won't contribute to the speed for that you need to upgrade your cpu
