Any comments on Gigabyte 4090? I can't find any comparisons for different brands when it comes to rendering.

Thanks. I'll check Noctua coolers and buy two sticks of 64GB RAM.

Hi everyone I am planning to build a new PC with following parts. Processor - AMD Ryzen 9 7950X Desktop Processor 100-100000514WOF Motherboard - MSI MAG X570 Tomahawk WiFi AMD ATX Gaming Mothearboard with 4 RAM Slots GPU - Gigabyte GeForce RTX 4090 WindForce 24GB GDDR6X Graphics Card GV-N4090WF3-24GD RAM - 32x2 Ripjaws 3200MHz i.e. 64GB total Storage - Western Digital SN850 500GB, PCIe Gen 4 SSD 7000MB/s R, 4100MB/s W WD Power supply - EVGA GQ 1000W Gold PSU I would like to know which CPU cooler would be best and budget friendly. I want to do VFX and motion graphics work in Houdini and Cinema4D on this PC. I intend to do FLIP, Pyro sims a lot. Please also share your comments on the other parts that I have listed. I want to do this long term investment for at least 5 years.

In order to delete the cache files in bgeo.sc format, I have to manually go to the folder in file explorer and then delete all the files there. Is there a direct way in Houdini that allows me to clear those files directly from node tree? I'm using 19.5.435 on Windows 10.

What is the difference between a vector and a 3 floats vector?

Thanks a lot @Atom and @Librarian for sharing the files. A small request. Can you also please share the links of the tutorials so that they can be followed along ?

Thanks a lot. The VEX code did it. Altering the roughness wasn't doing anything. Can you please explain what exactly is happening in your code? The normal is getting multiplied by a random number, which is very small. How come the velocity is not getting affected? For example, let's say I multiple 8 by 0.1, I get 0.8. So I will immediately see the difference. But using your code, I don't see much difference. Why?

I am doing a particle simulation. How to solve this banding issue ? banding issue.hip

Thanks a ton! It worked!

Done. Still blank.

Still not happening. I did the referencing like this. Please share a screenshot and steps of how to do it. dop smoke import question.hip

I am trying to import a pyro simulation in a sop network using dop import node but unable to do so. What should I do? dop smoke import question.hip

I am trying to do pyro advection of a volume. I am following this tutorial. https://www.youtube.com/watch?v=8VrbBE-XnXA The chapter 4a begins at 28min:58 sec. At 47min:37 sec, Steven changes bindings for turbulence from 'temperature' to 'density' and he is able to achieve advection of the volume immediately after that. However, when I do the same and I press the play button, my volume just disappears over time. It seems as if the binding for 'density' is not getting activated at my end for some unknown reason. Moreover, unlike Steven, my pyro solver is not creating attributes of vel and pressure. I tried the same steps in a new pyro solver but still I am failing. Screenshot from Steven's tutorial. What I experience. What should I do? volume advection issue_knipping.hip

Superb! Thanks a lot Ziyad!

This!!! This is so weird! I wonder why they made it read-only attribute. Thanks a lot! Do you know of any example where attrib vop is used to run over primitives directly? That will help me a lot in trying to understand why is there an option for 'primitive' in the drop down menu for 'run over' in attrib vop.
