I am trying to test out the Krakatoa/Frost combination but I’m having an odd problem.
I can convert an object to PRT and thus to Frost (to create a ‘particulate’ looking mesh, otherwise I could go straight to Frost) and then convert that back to PRT to render in Krakatoa (as per the tutorial you guys posted). The PRT is not showing up with anything in the viewport, but it is generating particles when I hit render. However nothing is rendering. My last settings produced 39 million particles, but nada renders.
It’s a very crude setup, but it will render okay with current settings if I just render the initial PRT so I’m pretty sure it’s just something up with Frost/Krakatoa but I cannot figure it out. Are there any obvious stumbling blocks that might cause this?
I posted the scene file (Max 2012) if anyone has a chance to look at it and tell me what I’m doing wrong?
The only obvious thing I see is that your PRT Volume001 is offset and out of the camera view. Its Transforms must be aligned to the source object for the two to appear in the same world space. The simplest way to achieve this is to click the [>] button in the PRT Volume next to the source name, navigate down the menu to “Inherit Source Object Settings” and pick “Align PRT Volume To Source Object”. Then you should see (and render) the PRT Volume particles.
There is also the “In World Space” checkbox in the “Source” rollout, but it has an update bug in the latest builds, so I would suggest using the above approach.
