Hey everyone!
This should be really basics but i just cannot make krakatoa run properly… it keeeps showing a black screen not even alpha channer. I read all the docs forums etc but thing is…:
Im running krakatoa 1.5 with 3ds max 2010
Change the renderer and set it to krakatoa
Set the materials render to scanline.
Activated the object tipes at the krakatoa main controll rollout.
Nothing works i really wish if somebody could help me out here. I recently installed it but i can’t use it. No information about this subject whatsoever.
What kind of particle source objects are you trying to render?
There is a Log file you can open from the Preferences rollout that will show you the number of particles Krakatoa received - if it is 0, nothing was found.
Also, after rendering, you can either right-click the PCache button or open the Channels rollout to read the number of particles and memory usage to see if any particles were actually loaded.
Try this:
Start a new scene
Create a Teapot
Go to Krakatoa category of the Create Geometry tab in the Command Panel, create a PRT Volume object and pick the Teapot to make particles from it
Create a Spot Light illuminating the Teapot particles
Assign Krakatoa as renderer with default settings
Hit Render - you should see RGB and Alpha of the particles you created
Thank you so much for this. It does render but does not show anything besides the particles. Does it only renders its particle system? I also set a teapot but didn’t show up onto the scene after render it. Anyways i’ll follow all the tutorials to see it all!!
Why does the materials has to be set to scanline?? It has a krakatoa meterial option but it does not show the spheres in the material editor (I saw your previous explanation about it).
It was my bad i was trying to render stuff like geometry but without any particle system in it.
I’ll make go through all the tutorials in order to gain more experience in it!
As explained somewhere in the tutorials, Krakatoa is a PARTICLE renderer. It does not render geometry at all, except for matte objects to cut out where an object would be. The particle rendering is then composited with the Scanline or VRay or mental ray rendering in a post-processing application or, if you don’t have one, in Video Post. We could make Krakatoa render geometry surfaces, but we decided there are enough solutions out there to do that and we are concentrating on rendering particles as fast as possible, with the least amount of memory possible.
When the Material Editor is set to Scanline, you should see the sample spheres as usual. When it is set to Krakatoa, the spheres used to show each vertex as particle, but that was broken later when we changed the lighting model. It might get fixed some day…
Please read everything you can find on the documentation page (esp. tutorials) and on CGTalk. Krakatoa is not just a renderer, it is an extension to various particle workflows that has been used successfully in heavy visual effects production (Avatar, G.I.Joe, Superman Returns). Applied right it can produce quite stunning results…
I’ll start the tutorials and go through all the way. I was actually doing the “Krakatoa Rocks” text tutorial but there is something that i just could not solve at all. There’s an option called “Scale Density using Material Opacity” i think it was a button on previouses versions of krakatoa but there is no more. Is it checked by default?
Yes, we decided that it should be on by default - if you don’t want to scale by material opacity, just set the material opacity to 100%
That tutorial is from earlier days.
Also I should mention that the Krakatoa Geometry Test operator in PFlow is disabled in Evaluation mode in v1.5.0 and higher.
