View Full Version : quick cumbustion question

04 April 2004, 06:46 AM
Hello every one,
i have a question about z-deph in combustion:
Let's say that i'm rendering a small animation with 3dsmax. I don't whant to render the deph of field in 3dsmax because of the increased render time and also cause a wrong dof will ruine all the footage. In stead I whant to add dof in combustion so i'll render z-deph pass also. The problem is that z-deph is not calculated corectly because i use an other render system and has some serious artifacts... now, i what to do the following:
render standart picture with all the effects and than, render only the z-deph map with scanline render.
And the question was:
Can i tell combustion what file tu use as a z-deph? And if not, is that possible in After Effects? More precise, can i use an other image to calcultate the z-deph in combustion? what about after effects

I also saved the image in .rpf and .rla formats but both use the incorrect z-deph image as they were renderd with the other render.
Thank you for your time.

AFAIK you cannot tell combustion which file to use as zdepth, however if you can render a "zdepth" pass as a sequence recognizable by combustion (tga for example) in which its only the greyscale image of your scene then you can use it as a source for a compound blur. I do this all the time from Maya using a simple shader network applied to everything in my scene. I believe the same applies for after effects.
