The help file doesn’t Seem to say anything about how to actually get many of the G-buffer options.
I selected the Object velocity option, enabled frame buffer.
I even tried turning on Motion Blur (someone said in one of the threads that velocity only worked if motion blur was on), although that would defeat the purpose, to see if that worked.
I always get the same results. It saves no file, and it is Black in the VrayFB.
Is no one else having this problem? I feel insane here.
After Effects comes with a free plugin called CC Vector Blur. I want to test it out to see if it’ll give me something similar to RSMB. I’ll put in a request for that software, but it sure would be nice to not have to deal with that. People can be real stingy first quarter.
seems there is a free MR shader for max6, but it doesnt work in later versions
for max7 this tip might help you to get motion vectors without resorting to combustion to split the rpf files http://www.revisionfx.com/generalfaqsMV3DSMax7.htm
If you go to the support.discreet forum for 3dsmax and search for velocity in the maxscript conference I think you will find a script that converts the vector information into an rgb image that can be used by RSMB.
unfortinantly its not as simple as just turning on velocity. This is due to velocity working with some other gbuffers;
to get correct velosity for rpf you need to enable the folowing:
velocity, render id, node id, coverege, subpixel weight. Then enabling correspondant gbuffers in rpf’s output will produce the correct motion information within rpf. You do not need motion blur turned on to get this effect.
the script I mentioned doesn’t require all those channels. in fact it will save the vector info as rgb for rsmb even as a tga sequence. I think the velocity vectors are generated whether you save them in a rpf or not.
