Title: motion blur birds eye exterior
Post by: jjduncs on 2014-05-29, 11:01:55

First go with Motion blur in Corona.

The project is my urban furniture assignment for uni.

Render took about 30 minutes at pretty high res.

Grass made by me and scattered with Forest. Trees are ever motion 58.

There are a few fireflies around the seated man, does anyone know a way to minimise these?

Possible causes of fireflies:

- The guy has absolutely white shirt (RGB 255)

- The bench has too strong bump map

- You touched Max sample intensity parameter

- Reflection of sun disc

I've Been getting them on objects with really low bump. Bench has 0.1 bump and concrete even lower.
Will check mans shirt to see. I think it's a light grey fabric map.

Haven't touched MSI.

Scene lit by daylight HDRi. I copied the HDRi and made it much less contrasted and Low brightness for reflection override so not sure if that would be the issue.
