Hi,

A very very short match move animation.



The compositing process is a little bit heavy as there is no alpha and mat shadows yet but it is doable with some tricks.

Short but good, i like the sound.

Cheers, mib

Thanks !

Well done. Good animation and matchmoving.

Thanks,

to be more precise, the model and textures are not from me.
The animation is a mocap.

What I did :
- character rigging
- mocap assignment and ajustments
- complete matchmove process
- spherical environnent hdr creation (to fit with my living room video shooting).
- render with octane (several passes for shadows...) / compositing

Wow I have messed with composting using octane and AE, but with not so hot results. Would you mind explaining a little more how you achieved shadow and were able to isolate the robot to effectively? I have tried doing multiple passes and using an luma mattes but there always seems to be a thin edge around what it was I was trying to isolate.

Great job!

Hi,

Sure,
I used a trick seen on this forum. I can't remenber were it was and from who (sorry) but the thing is a little like you already done I think.

For alpha :
use a pure white diffuse material for the ground.
Use a pure Black diffuse material for the object.
ajust your lighting, background image and imager so that the background become pure white.
Then you will have a black and white image (with soft transition for the shadow) usable in photoshop or after-effect as a mask.

Then render your scene with the object, ground and background normaly and compose it with your mask.

If your edges are not perfects (little bit of white for exemple), let's tweak your mask (compress borders for exemple) in photoshop/after-effects.

Yes very good composoting, some guide lines of what kind of passes you rendered, AE hints and any other advices would be a great help.

@HMK

Passes are explained just on top of your post : )

AE compositing :
-vector mask to separate the foreground (sofa and wall) of the video shooting.
-put your black and white sequence (alpha) layer on top of your colored sequence layer and apply "luminance de silhouette" (you'll have to translate because my AE is french) on your alpha sequence as layer style. ( The result is the equivalent of photoshop's fusion mask ).

WOW! very well done.
