Dissolve Effect

#61

Hello Bobo,
I’ve been testing and testing several movements of the particles.
Yesterday I pass it to high res. From 1 in random in cube to 10.
It took me almost one hour to render one frame but it was my surprise when I came to see that The difference between high & low res isn’t that significant.
I can only assume it’s because of the lack of depth?

Hey Vitor that looks pretty cool :slight_smile:

Thanks, really appreciate.

Hello Bobo,
I have just a doubt for you.
I’m testing agian this Dissolve Fx and dedided to do waht you told me here:

Instead of just rendering, you can switch Krakatoa to “Save Particles To File Sequence” once again and dump all the force-influenced particles, their Velocities, Colors, Density etc. to a new PRT sequence. This will allow you to load the resulting simulation in a PRT Loader and apply post-processing of any channels via KCMs, play with the Density multiplier, tweak the Motion Blur settings, reduce the particle count if needed, cull portions of the particles, even DEFORM the particles with deformation modifiers etc. and it should take a couple of seconds to load and render ANY frame because PRTs are history-independent snapshots of the particles (you can jump to frame 100 without pre-calulating 99 frames each time).

Don’t I still need to do this:

Since there is no lighting in the scene and we want the particles to appear self-illuminated, Turn on “>Use Emission” in the “Main Controls” rollout of Krakatoa; In the “Global Render Values” rollout, click the Create New Global Override Set - a new helper object will be created in the scene and a Krakatoa Channels Modifier will be added to it automatically.

I’m asking cause I try to do this and got some strange results.
Cheers

Define “strange” :slight_smile:

You will be able to override the Emission later at any time.
The saving to PRT simply bakes most of the time consuming portion of the PFlow system and trades off time for disk space. It will eat up a lot of disk, but will let you iterate faster.
Of course, you can save the Emission channel and then the self-illumination will also become part of the baked particles.

STRANGE because some parts of the particles were gone.
I’ve decided to add the Emission and MXSFloat to the save channels.
I think this is the correct thing to do, right BoBo?

An render example:
Why is this happening.
What I’m doing wrong? Do I need to had anything extra?
Cheers

I’ll recreate the process to see whats wrong…

I’m feeling very embarrassed at the moment and quite stupid.
The problem was related with the camera.
I didn’t created any so I was using the top view.
I was going crazy trying to find the solution for this and then I rendered from the perspective view and everything turned to be alright.

I did what you told me too Bobo and activated the use emission.
Now I’ll had some effects.
I’ll post my results.
Thanks

Don’t feel stupid, Krakatoa has some limitations when it comes to clipping planes of ortho views.
We don’t recommend rendering from non-perspective views, but it is not very obvious from the documentation (not that anyone reads it ;))

Btw, good job on the thesis, I skimmed over the surface (mostly looking at the illustrations).
Congratulations on the Master degree!

I usually print all the Help of the softwares I use.
I’m also reading Krakatoa, probably miss that part but It’s really true.
I always read the help.

Thank you about the Master Thesis, I’ve lost my appendix don’t know where they are, it will take some time again to put them online.
The Master Thesis is more a reunion of information, related with Fluid simulation.
I think I did a good job in recollecting the basic information for anyone to understand how to create a simulation.

Now it’s time to work and finish the showreel.
My next step is to start learning python.,
I have to learn how to program.
