Re: deformation motion blur blacks out cluster materials

How do you deal with shadows sampling and texture sampling ? I can't
find a way to remove aliasing problem when I use rasterized mode.

If I use a big collect rate the problem is still there and the render
time are huge. I must use the default scanline on some shots where
rapid motion did the job far better in the past with 4.2 ( a lot of
geometry ). Since mr 3.4/rasterizer mode, even geometry details are
faster to render in normal mode.. I use something like 1-3 with a
threshold of 0.001, and the render farm is so happy !

No, it works in some situations... but you have to be very aware of the limitations (which isn't very well documented I heard). Like, problems with clusters, problems with 2ndary or primary rays turned off somewhere in the pass, reflection, refraction and so on. We have been using RSMB for FxTree (very fast) or AFX and XSI MB (sans Rasterizer, for rotating things and so on) a lot lately and it works quite fine.

 

Stu spends most of his days rendering Lambert spheres... I guess thats why it works out for him. ;-)

It woks for you ? I'm interested as it looks completely broken to me. You use 5.01 or 5.(secret) ?

Hey! The Rasterizer is my friend!

 

Okay, so I had to sell my sole to the devil and sacrifice a few chickens….but it works for me!

"isnt there a known bug in 5 with objects randomly disappearing with motion blur?"

 

Do you have the Rasterizer (a.k.a The Root of all Evil) on?

isnt there a known bug in 5 with objects randomly disappearing with motion blur?

Nope, geometry definitely not intersecting and renders fine now that I've re-jigged the textures to avoid cluster materials.  Reckon I'll CAB the dodgy scene to Softimage.  (expensive fare – ho! ho!)

 

I'll bear in mind the close faces thing, Kim.  Thanks guys : )

are you rendering both front and back faces? possibly the back faces are coming through and obscuring the front.

 

close together faces, apart from giving problems with depth sorting, can hammer render times I've found in the past.

Hi folks,

 

I'm animating pages of a book (using IK chains) and so need to check 'Deformation Motion blur".  Only trouble is that the cluster material on the B side of the pages goes black - huh ?!?!  

 

I can workaround this by making a texture for A and B sides in one image and redoing texture projections, but wondered if anyone else has found this? is there a fix?  Or is it just another case of avoid cluster materials at all costs!

 

Cheers,

 Olly xxx
