Title: Tiny green spots in render
Post by: 3dwannab on 2014-01-22, 23:33:06

Please see a test render, render set-up and sun settings. It's my 2nd try using corona and I love the simplicity of it. Problem I'm getting is the render has tiny little green spots (some circled in green - there are too many to circle!). Has anyone dealt with this problem before and know the cause?

FYI:
- Grass was created with a script found here: http://www.themantissa.net/blog/2014/1/20/grass-generator-v1 (see settings used attached).
- With the script it assign any number of ids up to 100! (I used 5) I then applied a multi-subobject material with 5 ids also with various different shade of green. No transluency or anything fancy. Just standard corona mat with different diffuses.
- Converted it to corona proxy.
- Used Cscatter to scatter it over a plane.

Please feel free to ask for more info if needed. Thanks.

See attached screens and .mat file. Also passes 7, 26 & 50. You can see the green dots fade away. I'm sure after 70+ passes they would be gone entirely. I will test that tomorrow and report.

yep, it is just normal random noise, nothing is wrong here
