One thing to note, at 37:28, I forgot to set the Volume source of velocity to a vector from scalar. It's important to change it to a vector for this to work correctly. With it set as scalar, it only fetches the x component of the vector ie. only our x velocity is copied in.

Very nice cheers. As an input since it was touched on at the beginning of the video. Facial interaction not a must, clear sound and visuals far more important unless you're demonstrating something with some neat camera work. I notice you zoomed in at 39:00 at the code for the aw, very helpful as I've frequently had to stop and press my face at the screen discerning blurred text! especially when I use fullscreen (what's really odd is if I use an apple tablet, crisp as you like, eh)

This tutorial is gold, thank you Moeen. Btw, that blackboard where you explain the different solving methods, where can you get it? Is it a downloadable app?

No problem, you're welcome! I used Krita for that. It's a free drawing app. I just threw a chalkboard texture on there for the background and chose a chalk type brush. I also have a drawing tablet that integrates with it. I hope that helps😁

as Always, its amazing how you can provide to us such quality content :D Also... I have Three questions: 1.Will you do videos about ragdoll solver? 2.What about WhiteWater SOP Solver which will be in Houdini 20? 3.Maybe not about fluids, but what "burn" attribute does in Pyro Solver? Every Field in Pyro is not much trouble for me besides burn. I really dont know what this is doing , why and how. as simple as possible :D Ty!
@felixxia3604
@felixxia3604 8 месяцев назад
Burn is needed for fire. If you dont need fire ( just smoke ) you dont need burn. Burn is a field, which is an attribute for pyro. Go get gnomon' pyro tut, lecturer is alasgar hasanov. That is a good one and still quite up to date workflow wise

once again, you have provided such a wonderfuly comprehensive and cool tutorial!! Thank you so much man. One question, when i use the file cache, even after caching the simulation runs very slow. Am i caching improperly? Or is my PC simply too slow? for refference im on an intel i7 and rtx 3070 ti, 32 gb of ram. thanks again!
@NineBetween
@NineBetween 8 месяцев назад
No problem, you're welcome! So, firstly, ensure that the file cache node is set to "load from disk". There's a checkbox that you can tick to make sure it is loading from disk. Additionally, it is dependent on the speed of the drive that you're loading from. If it's an HDD, it will load slower. If it's an SSD or an NVME, it will load faster. Your PC specs seem more than sufficient, so just make sure that you are loading from disk. Let me know if you're still having that problem👍

I couldnt find the video where he explains why he lower the particle scale inside the volume rasterize, is there a reason why he goes to 0.05 or in wich video he explains it ¿?
@12miikee
@12miikee 8 месяцев назад
I love your tutorials, the way you explain things is so good and easy to understand really :D
@NineBetween
@NineBetween 8 месяцев назад
Thank you! I appreciate the kind words. In the two volumes videos I explain how it works. I'll go over it quickly here so you don't have to go find it: The particle scale is set to a default value of 1. This means that each particle is treated as a sphere with a diameter of 1 unit. This causes massive volumes because each point is effectively a large sphere. The value should reflect the size of each particle. 0.05 is just a decent value for the scale of our scene, but it's okay to go higher or lower. Additionally, if the points being rasterized have a pscale value, then Houdini multiplies the pscale value by the particle scale value. eg. if a particle has a pscale of 0.1 and the particle scale is 2, then the resultant scale will be (0.1*2) or 0.2. I hope that helps!

Shouldn't you be doing your dopnet on the object level and not the geometry level?
@NineBetween
@NineBetween 4 месяца назад
Hey, there's no significant difference. In fact, the newer workflows encourage SOP level solving. By doing it at the SOP level, it removes a layer of separation in some way. It allows data to more easily flow from the dopnet into the rest of the network. Again, it isn't a major difference, but if you prefer separating your dopnet out to the object level, you can. I hope that helps😁
