In 3ds Max how can flickering be avoided in animations with generated starfields?
show user profile  dcace
I'm trying to create a starfield for an animation and it appears to flicker when viewed. The starfield is a material with a Composite for the Diffuse and the layers use Cellular to generate the effect. Even with just one layer of Cellular the animation flickers. I've set an Instance of the material as the Environment Map instead of using a Skydome.

Here are screenshots of the material editor:

Here is a sample of the animation: (Will need to download to view)

I'm using 3ds Max 2014. I'm new to 3D modelling/animation so please let me know if I need to provide more information. Any help would be greatly appreciated.

personally I would do all that in post, but you want to increase your sampling, which will increase your render times.

Sorry what does that mean?
Do I need to change from the default Renderer to the NVIDIA mental ray renderer to be able to effect the 'Samples per Pixel'?

You could try to enable super sampling, but it's been so long since I used I'm not too sure.

To be honest, yes you are better off switching to Mental Ray. It's more up to date, can produce better images, is easier to find information and tutorials on and is in many ways much simpler to get to grips with.

i've done this type of thing, but it has work best for me without creating the stars in Max.

for example, i've created the stars as an image in Photoshop and plugged it into a shape as a diffuse

it's usually helped me reduce flicker without cranking up the samples

change the speckle reduction from normal to High or Very High in the render window.
Its helped me in the past, but its not a total fix. barely changes the render times (at least at 1280x720)...
