Particle advection/camera projection

Postby litote » Tue Aug 22, 2017 4:54 am

Hello,

In Bobo's webinars he shows a car being turned to dust. I have been able to achieve this effect with the C4D Krakatoa plugin using TFD and camera projection. Is camera projection also the method used in the Krakatoa for Maya plugin for this effect? Can someone tell me the steps, or better still, point me to a tutorial? I have no idea how to link up the camera projection with Krakatoa -- assuming that is the method used.

As a secondary question, I also tried using Maya's 2D container with Fluids-Add/Edit Contents-Paint Fluids Tool to convert an image to particles, but don't know if it is possible to use another emitter inside the container to further drive the particles, though I can use Field/Sovers like Turbulence. Anyone happen to know?

For the projection mapping effect in Krakatoa for Maya, I used a custom Magma setup to generate the sticky UV coordinates, and then mapped a texture using them. It is the last video on the KMY Magma Webinar page: http://www.thinkboxsoftware.com/krakato ... a-webinar/

I believe the actual flow was posted somewhere at some point, but I am on the road today, so I might be unable to find it immediately...

Thanks for your reply Borislav. I appreciated your series of webinars for Krakatoa for C4D. Now I am making the shift to Maya and learning the workflow all over again. I will definitely watch that Maya webinar.

Please post the flow or whatever further details that are available when you have time.

This disintegration effect is what I am aiming to reproduce in Maya -- I created it using Krakatoa with C4D/X-Particles/TFD (effect is at 1:28 in the reel) :

Poor Miley :lol:

I knew I had posted about this before, did a quick search and found this thread, which also contains the link to the sample scene with the Magma in it: https://forums.thinkboxsoftware.com/vie ... 4&t=11753&

Please read the thread, download the scene, and let me know if you have any further questions...

Thank you Borislav,

I will be read through the thread and dissect the project file and try to recreate this.

Much appreciated,
Greg
