And wy the droplets are static like glue

Nice work, but I'm wondering :  why are the calipers and brake discs not spinning ?

thanks Guys,

kahein yes thats true, when i get time im going to shoot water droplets on glass and film it on my 5D the comp it in/ use as an element. As the simming process wont achieve a realistic result in a short amount of time.

Faouez, yes well spotted, for that shot they werent. When i did a test with motion blur with the disk bake spinning it looked exactly same as not spinning (as the disk brake is a flat material). The render time was really high, so i stopped the rotation for that shot of the disk brake to speed up render time.

thanks guys for your great feedback :)

Dust particles seems too far away at some point and I would adding some glowing headlights. could add much meer depth and also because the rearlights are indeed active.

thanks fellazb, i did do a render with the main beam on the headlights, but it looked very distracting. So decided to turn it off.
Yes the rain mist look away from tyres will try fixing.

When i get some time im going to film with 5D some water droplets on glass and blow some air. Then comp that element in on the car bonnet to get realistic water droplets moving.

Cool look all in all. How Long does it render per Frame to get to this result? And what Kind of machine do you use?

Rendered at 1280x720 7min - 10min per frame, my machine is 32GB ram intel i7 3.4ghz 6cores 12threads not super powerful

Hey guys a personal project , wanted to capture natural camera feel.
Creating realistic camera shake (linked to car suspension) , lensing choice of lenses, composition (with camera chase car rig).
Rendered with 3D motion blur and depth of field in Corona. Render time was 7min - 10min per frame.
Spray was created in FumeFX and rendered in Vray with openVDB.

[Max] Feature Requests / motion blur shutter curve

« on: 2015-12-12, 18:05:12 »

hey guys,
really loving corona,
Just one thing i would really like is more realistic motion blur. which can be easily received.

Great if we can get a shutter curve for camera motion blur.

We carried out some testes to match motion blur from are Arri Alexa footage and couldn't get the motion blur to match accurately. (we matched the speed of the disk and set the shutter speed same as the camera)

we shot test footage like this:



However we did mange to get the motion blur to match accurately with in Arnold using the shutter curve and rolling shutter parameter and would love to see this in corona please.

Would love to map a curve like this to the camerashutter curve:

Arnold camera settings:


Renderman details on shutter curve more info
http://renderman.pixar.com/resources/current/RenderMan/cameramodel.html
http://renderman.pixar.com/view/motion-blur-and-depth-of-field

The reason why this is needed. Is the default motion blur shutter efficiency is too flat (no delay in shutter efficiency). This gives motion blur a very linear look. With having a ramp for camera shutter curve you can map the camera shutter to say Arri Alexa or any other camera. Making your render sequence match with your live action back plate more realistic.
We have esp noticed when rendering CG cars that the default motion blur not looking too great and lacking the feel of mapped shutter curve.
Please can you add this feature we are really loving corona.
cheers
