Transparent rendering using raytracing.

I'm sure this has been asked over and over, so my apologies.

I'm familiar with using opacity/transparency masking w/ the micro-poly render. No problem. But for some reason I'm unable to come up with a way to get the same thing to work w/ raytracing. The leaf color images appear but is surrounded by the remainder oi the texture rectangle - the black square phenomenon.

Any hints would be greatly appreciated.

TIA -

It should work the same way, so I guess your opacity mask is not correct, or you didn't check the 'use alpha channel'. I always work with a tif with a black-white alpha channel, which works perfectly. I believe some use a transparent tif or png, but I don't know how that works (as opacity is off, or on - from 0.5 and higher).

I'll give it a shot. I'm a-thinkin' image bit depth may be an issue, too. And yeah, the appropriate checkboxes were checked. Back to the salt mines...

Thanks for the response. I'll let you know how it works out.
