sorry for my bad english, it is not my mother tongue.i just finish a car render project last week,and i got a lot motion blur issues during the production. so,here is a little tip for all c4d users,if you get the same issues, this tip may help you.
problem screenshot
- SPIN WHEELS doesn't display in the live viewer
- sometimes,live viewer give you the right motion blur preview
- But,when you hit rende to picture viewer,you animation look like this,the car floating on the air,or the wheels fade into the car mesh.
solutions
1.for not heavy animation project
keep the wheels object rotate itself,do not drive by a null ojbect or other parent object.
in this case,the car simulation make the car body mesh move forward,and the car body mesh drive the wheels null objects to rotate the tires and wheels.simply just keep the wheels group keyframes andremove all of your other keyframes if you have baked you simulation,and move the floor plane backward to get the same animation.
- A good exsample of motion blur rendering
-------------------------------------------------------------------------------------------------------------------------
- For a complex car animation,the motion blur always get errors in default set up.
if you car animation is more complex, you can't use this method.
2.ultimate solution for best motion blur quality
i find a solution in maya octane board.it seems the c4d and other 3d program can not give octane plugin enough data to calculate the motion blur correctly.i feel so luck that the solution in maya form also works in c4d,maybe other 3d program also.
so here is how i solve this issue.
- First,change your project setting and render setting.give the frame rate 10 times then your project set up. ex. my old setting is 25fps,give it up to 250 frames per second.
- use octane live viewer to export orbx files to standalone program.
- change the frame rate back to 25fps,and select your render target set up render method or samples etc.
- there we go.the perfect motionblur effect.
After all,use Octane standalone to render your project.done!
hope this tip will help you.
