Great tutorial! If you’re using Fusion to composite, we developed a plugin to to do both your post DOF and Motion blur as one pass, so the end result is more accurate. You feed it both the velocity pass and the z-depth, and it calcualtes ONE blur value, rather than doing a blur, then another blur like this method.

(look for the Motion Depth Blur tool)
Again, it’s not the best solution (real 3D MB and DOF are better), but really who has the time and resources to wait for those kinds of renders all day
Great article! Thank you!
I’ve been using the same tools myself, but have been having problems with the velocity artifacts. The blur trick is pure genius, that’s exactly what I needed!
Great one man. I was wondering witch one Alex Roman used for that video and here is the answer…Lenscare! Result looks awesome!
Also useful tips for RSMB. I’m using that one for a long time but this is really interesting technique.
EXR looks cool but tell me does it records camera movement too like RPF or RLA?
Nice to see someone still uses 3ds max + loots of tutorials
Sweet!
All the best,

Yah, I “tried” to get prime focus to give us a deal on that tool, but they were stingy and were gonna charge us full rate. We are a fairly big Deadline customer (over 40 nodes), you’d think they’d throw that in for free. I agree though, real DOF and Mblur cannot be beat for quality. We actually used 3D DOF and Mblur on a recent job for Cartoon Network. Check it out here.
Glad to help any way I can!
Thanks for the comments! Sorry but EXR’s do not hold any camera animation info. But they do hold a ton more info than an RPF. If your trying to get camera info into After Effects, try Max2ae. That tool is amazing.
