Krakatoa 1.6.0 Rendering Introduction Videos

#15

the first two tutorials for krakatoa that I totally understand :slight_smile:

Bobo, I’m wingless from the wall of commands that opens in the krak UI…
running the risk of looking like Homer Simpson, I hope one day come a more digestible UI for noob users :wink:

#16

I admit that it LOOKS scary, but it isn’t really.
Version 1.6.0 removed half of the rollouts in the Krakatoa floater, and once you live past the initial shock, it becomes very logical. It IS possible to create an alternative UI for newbies (the whole UI is scripted), but then you wouldn’t be able to use some features, or you would be slower navigating around (a large number of the controls in 1.6.0 are for navigating to other places - the top row of buttons and the last 3 rows at the bottom of the Main Controls).

I will try to provide an alternative UI some day, just for fun… :slight_smile:

#17

yes, a 3 buttons UI would be nice :slight_smile:
however, you are right…more working with it and more digestible is the interface … but you still think of a “dry” IU…:wink:

#18

There is a “Krakatoa Toolbar” category in the Customize UI dialog that provides most options as MacroScripts. You can add those you think you need to a toolbar and use them instead of the Main GUI. But the things you will be able to do with Krakatoa will be very limited that way.

We are not adding buttons for the fun of it, but because with great power comes great … flexibility. :slight_smile:

I just posted Part 1 of a Krakatoa NPR demo:

It discusses shading of particles using MagmaFlow including Lambert shading and simple Toon shading without the creation of actual scene lights.

#20

You are the best Bobo.
Huge thanks.
Cheers

#21

That’s hardcore! I always wondered how this shading works but was lazy to find out :slight_smile: Thanks Bobo :bounce:

#22

Thanks that was very enlightening :slight_smile: this is a great series you have going on very educational, as always.

#23

Here are some results produced during the preparations for Part 2 of the NPR video.
Try to figure out how to do these before I post the tutorial…

Hmmmm, how long till you post them :slight_smile:

#25

Typically I produce videos over the weekend.

#26

Absolutely fantastic.
Cheers

#27

Great info. You should definitely put this up on the blog.

#28

krakatoon…vs pencil+ :slight_smile:

#29

Haven’t been able to replicate them but some thoughts :slight_smile: :

The ink looks nice very solid, thinking just a real close variant to the original tut, with the gradient something like 0-10 black 11-100 white?

The four pencil stroke looks like your messing with four steps of motion blur

LOL no idea with the pencil, something with a cellular shader?

The charcoal is hard to tell, a falloff in density?

The smear strokes look like your pushing along a vector.

#30

I just posted Part 2 of the NPR tutorial.

It shows only the Ink (same as Part 1 just without the Paint) and one of the many possible pencil styles based on shifting particles along a velocity vector perpendicular to both the camera view axis and the normal, which happens to be the tangent of the outline…

Johnny’s guesses were pretty close to the actual techniques used… Good job!

#31

Sorry, it is available.
Thank you Bobo.
Cheers

#32

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 :wink:

#33

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.

#34

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