I'm quite sure you have not set the buffer_api to +rgba.. read well the posts.
you'll have interpolated images then use at least 0,1 as sampling to get nice results also for the buffers. the difference in sampling someone reported is a thing you should fix in post.. framebuffers in general have this kind of problems. don't blame too much the tools.
and last thing I also get some random crash, but it happens for all the operations that require maya to read/write from/to external files, we get the same kind of crashes also with lightmaps and for example miss_fast_skin. mayatomentalray sucks !!

Could someone please explain that?

What is a buffer_api (google: 0 results, CG-Talk: 0 results (except this thread ) ?

Thanks,

Quote: Could someone please explain that? What is a buffer_api ...

buffer_api is actually nothing. I removed it from the pack. please floze remove also your links.
it was a 'legal' way to implement from maya extra options for mentalray. but it is in any
way stable. it does not only crash the scene sometimes but it really brings instability to the
whole maya apz. randomly
why this? I donno. maya doesn't crash for the buffer_api itself. the problem I see is that she
cannot handle the buffers enabled in that way, she crashes most of the times on internal
operations like adding the temp buffers or while removing them, these activity is not
controlled by the ctrl_buffers.dll. I have to say that geometry api implementation
is not supported by the mayatomr plugin. buffer_api works perfectly on xsi and standalone
and for what it does there's no one point in getting that instability to maya.

you're back to 8 stable framebuffers.
( dw it from the first page )

ciao
francesca

Actually francesca's files work fine. They're in gzip format though, I recommend getting a new winrar version - however, it really should work!

ok thank you,

back to the old question:
how do i get the anti-aliasing / interpolation working?

Hmm... as soon as my primary buffer exceeds the value of 0.008 the sampling works perfectly. Is there an explanation to this? Or is it just some mr voodoo?

edit: However, it doesnt seems to be antialiased against the 'background'?

by enabling the buffer.range from the buffer_write you'll get interpolation by default.
you can ctrl this in the mentalray verbosity as I posted early.

RC 0.2 info : option: image type interpolate
RC 0.2 info : 0 rgba yes
RC 0.2 info : 12 rgb yes
RC 0.2 info : 13 rgba yes

the 13th is the first valid user buffer on maya6.5 and it corresponds to your user1 channel.
you'll need also a decent sampling from the renderglobals.

occlusion.user1.0.iff


maskbck.user2.0.iff

the blur comes from the jpeg compression

Sorry if haven't checked for any places, but did you release these framebuffer shaders for xsi as well? I'd be very interested in those.
