Interesting, I was wondering how to get/set the vector length, good practical exercises for the "to space" conversion ops. Thanks

Still really digging on the Holy Grail of pFlow

A small note about that - although it does not affect that specific example much, it would make more sense to switch the FromView operator to "Vector" mode since it operates on a vector and not on a point. When applying the transformation in Vector mode, the translation part of the matrix is set to [0,0,0]. So for most other variations of that example (e.g. the slanted strokes case I showed a Quicktime of), you would have to use Vector mode of the transform operator.

I think I understand, so this would get you an actual direction to use, is that correct?

We want the vector [0,0,-1] to be taken from View Space into World Space. In the process, we don't want to translate it, just rotate it so it points along the camera. If you want to use the vector [1,1,0] to define a 45 degrees vector in the image plane and then want to shift particles in world space so that they still coincide with the image plane no matter where the camera is, you MUST switch the FromView to "Vector" mode, otherwise the value will depend on where the camera position is relatively to the origin and the vector will not be parallel to the image plane.

In the video example, due to the placement of the PRT Volume and the viewer, using Point mode instead of Vector did not mate a big difference to the [0,0,-1] vector, but it is indeed a mistake. I am just too lazy to rerecord the whole thing, so I might just add a bubble and explain it on screen in the current video...

Bobo,you are good man!Thanks for your YouTube videos!
So unluckyly ,i can't open the website!Could i consult you some question?

When i want to save sequences to render by Krakatoa,it shows error:
3ds max attempted to crash,but the Krakaoa GUI caught the exception.
I only render one Frame at one time.It was why ?
By the way,how to render shadow channel that the particles on the geometry by Krakatoa.For example,the shadow that the particles on the ground,and the ground is matte.

Thanks a lot!

Thanks so much Bobo for adding Closed Captions/Subtitles -- you made the Krakatoa videos accessible for Deaf artists including myself. I can now follow without any hassles.

It wasn't a conscious decision, but now I am glad I took the time.

The story went like this: Google has this module that tries to auto-generate CC through speech recognition. The result was the most amusing text you would ever see - funnier than translating an English text into Chinese and back into English via an online translator. It had so much political nonsense including words like "taliban" and "chaney" I simply could not leave it like that. I could not figure out how to effectively disable that "feature" so I decided to download their time code file and rewrite it all by hand to make it reflect what I was saying. I really hope Google is using the submitted files to "teach" the speech recognition system new vocabulary...

On top of that, I have a terrible accent and assumed many people might wonder what I was saying...

I still have to process the last two tutorials (Toon shading), but now that I know somebody depends on the CC, I will do it gladly!

Cheers!

Let's start with version numbers - what version of Max, Windows and Krakatoa are you using? Are you running a commercial, evaluation or some other version of Krakatoa? Are you running in 64 bit? What are you saving - Particle Flow, TP, PRT Volume particles or something else? Any additional info would be useful.

The error you see is caused by a Max crash similar to "Unknown System Exception" in MAXScript - something went wrong somewhere deep in Max and it is unclear what it is. The code around the Render/Save button of Krakatoa catches that and shows the message you saw. If you would have pressed the regular "teapot" icon in the Max toolbar, I suspect Max would have just crashed to desktop.

I don't know why it is crashing though, Krakatoa is very stable for me and I have never really seen that message in my daily practice. There must be something wrong with your Max installation or scene, but I don't know what it is. There is never a good reason for Krakatoa to crash, so it is not expected.

Please provide more info.

Thanks so much for your particular help! I use in windowsXp 32 bit,and it is the particle flow emittered from the motion bip.When i rendered in a new scene,it was not error.I think it was my scene is wrong. I only redo it !
Thank you,Bobo! It is my project.

The error you saw was most probably caused by memory fragmentation. Windows 32 bit provides only a limited amount of memory to 3ds Max (as you know, default is only 2GB). This memory can get used up in chunks which can cause a memory allocation to fail depending on how long Max has been running. Thus, in some cases simply restarting Max and reloading the scene could solve this issue. So it is a fundamental problem with 32 bit computing.

In general, we do NOT recommend using 32 bit Windows since Krakatoa is one of the most memory-demanding applications out there. You should be prepared to see a lot of these errors when you push the particle counts higher...

Oh,so it was!Hehe,my computer‘s configuration is low ,only 1.5G.
Thanks,Bobo!Wish you have good night! ^_^
