Is it possible to use this technique with reelsmart motion blur in fusion (or AE or Combusiton)?

Can we use it at all in fusion?

Only *.mt from the mental ray renderer... Javier Mansilla Hi German,

I think that not is possible to generate a *.rpf output inside xsi, maybe i”m wrong? Only *.mt from the mental ray renderer…

It adds the possibility of adding motion blur to a RPF file rendered in 3DS MAX, XSI or other 3D application. You can download a free demo from http://www.rpfmotionblur.com Also, a free RPF Viewer application; useful for fast viewing rpf in win xp http://www.rpfviewer.com Thanks a lot, hope you like it German Heller 3Dar Inc. http://www.3dar.com Hi people -

You should take the maximum of the maxima, as in my previous reply. 2. Do not use realsmart, in realsmart mode the conversion from motion to rgb is different. 3. That''s just a possibility that I prefer. I don''t love overrides, and this way you have just a single instance of the shader. Besides, I also wanted to show a different, and I think more elegant, way to render passes. As mentioned, linking a shader to the lens and exploiting the State nodes allows you to easily export other kinds of passes. Stefano 1.

I''ve notice that the max displace value, changes every frame, so i don''t know witch one to choose for the entire animation. 2)Using your tecnique, should i choose :ReelSmart or SmmothKit in the lamaison plugin ? Beacause if i choose ReelSmart and I render with a value like "1" it renders all with bands of color, not gradient, with a complete wasted vector motion blur. If i choose SmoothKit, it work well also with "1"; rendering with Smookit works the same then in compositing in AE with Reelsmart Plugin ? 3)I can''t understand why do you use this "lens" tree, and not an ovverride pass on the objs ? Can you explain it to me ? Thx for your replys ! Simone ;) Hi Stefano, i have a couple ( maybe three :D ) of question.

1)How do you “check the maximim Max Displace animation wise ” ? I”ve notice that the max displace value, changes every frame, so i don”t know witch one to choose for the entire animation.

2)Using your tecnique, should i choose :ReelSmart or SmmothKit in the lamaison plugin ? Beacause if i choose ReelSmart and I render with a value like “1″ it renders all with bands of color, not gradient, with a complete wasted vector motion blur. If i choose SmoothKit, it work well also with “1″; rendering with Smookit works the same then in compositing in AE with Reelsmart Plugin ?

3)I can”t understand why do you use this “lens” tree, and not an ovverride pass on the objs ? Can you explain it to me ?

Thx for your replys !

Simone ;)

I prefer my way, because I don''t have to care for normalizing at all.

for Erin > from La Maison’’s website >>

A simple way to retrieve a good estimation of this value is to activate the logging of MentalRay Progress Reports (in the logged message tab of render options) and render an image showing the maximum objects motion speed

You will get the following information when the rendering ends, either in the message bar or in the logged messages part of the Script Editor:

“INFO : “PHEN 0.2 info : [lm_2DMV] >> Max Displace -> 29 pixels”

Note the ”Max Displace” value and set the shader ”Normalize” parameter accordingly.

thanks for the article Stefano
