particles rendering

[svenip]

compose them

[empleh]

You have to composite the software and hardware render together using something like after effects. Or choose a particle type that you can software render.

thanks:)

if you want them 102% in software, do them using particle instancer

I know this is a really weird/stupid question but what does composing involve and what is it used for?

[playmesumch00ns]

compositing just means putting together two images. After effects and Premiere are good programs to do this for you if you've got clean alphas, but you can do it in Photoshop too. You just render out each element - i.e. your software-rendered scene and your hardware-rendered particles - seperately, and then put them back together again using the alpha channel information.

At it's simplest level this could mean putting your name on every frame of your animation, and at it's highest means getting a CG dinosaur to eat a live-action person

hhmmm is it possible to make an alpha background in Maya? 'cause I don't wanna delete all the frames' background :(

If your background was blank (default black), and you saved it in a format that supports alpha (ie .tiff, .tga etc), then you already have alpha channel info. But if you already had a background then chances are you don't have an alpha anymore.

Sounds like you have to do some re-rendering.

If your scene camera is animated, then just render out the camera animated and your background visible (hide your foreground objects). The do a second render job in the same scene with the foreground objects visible and your backgrounds hidden so you have a black background. Make sure you save your files as a type that supports an alpha channel. do this process for all of the elements you'd like to have compositing power over. This is referred to as rendering in layers. It can be very handy for tweaking and process more quickly then rendering out the entire scene everytime you make a small tweak to a specific element.

hehe I found my mistake. I saved in jpeg *slaps himself silly*
