Animation grass flikering

[AndresAhumada]

Hi Guys


Need some help here.
I have flickering on a grass yard. White splotches.

Its a simple camera move. like flythrow.
And animated trees whit wind.

Cheers

did you check "subpixel mapping" in ColorMapping section?
Let´s see a sample...

Humm i dont click that!

You probably can't have irradiance map with moving geometry. So either calculate the gi with trees off (not visible to gi) or use brute force / light cache.

Its BF+LC

Its very strange situation. Look the settings.

[Morbid Angel]

Yeah so your retrace is pretty high, and 1000 samples is pretty low for such detailed scene like this one. Lastly flythrough I believe assumes nothing is moving.

Try single frame instead, 2000 samples and rertrace at 1 or 2.

The trees are in moving. Very slow wind.


Only the trees.

it does not matter how fast they are moving. Moving means offseting samples, throwing them around the scene if you will.

hi Andres, first...looks realy nice what you made!
After seeing your video, the subpixel theme isn´t the point, better let it Off.
Ok, I´m no MaxMan but as I can see in your render settings...
...Use cam path is on - cool!
...but than you set the Mode to Fly-trough! and there is no LC prerendered image inside the loader! (or is it not vis here!?)
When you set the render to "cam path", did you saved the result of that calculation? - which you´ve to do.
Then you set the mode to "from file" and load the cam-path result back here.
When you didn´t do that it´s no wonder to see the heavy GI flicker.
Good luck

hi,
also bottom left it looks like grass geometry is flashing on and off.
are you rendering across a network. can the machines see the shared assets ?
good luck

Hey, thank you all for your comments. They had been very usefulll.
The problem was that i forgot the "save LC"... oops 😛.

Now its fixed.
