A small problem with hair or leaves in this case.
I render the tree and the top comes in lighter then the rest of the tree.
How do I fix it?

Also I need to render this out as a image/decal with the background as transparency. What would be your approach?

Hey-cool tree! I don't see the top being any lighter...what do you mean? For an alpha channel, render to TGA format with alpha buffer ON...or try a PNG file, I haven't used PNG yet tho but I know it supports alpha/transparency.

Thanks for the info.




Sorry for the late response. I had a long scene almost done rendering. Just to find out it needed to be at night time.

I found out this seems to be an old problem. To do with the “render lines” and “hair system”.

I found if you put a small patch above it, it renders fine.

An excellent reason to render with light buffers to EXR format. Then you can just change the lighting in A:M Composite to look like it's night.
I think I remember hearing that all lights must have values other than 0,0,0 or 255,255,255 in order to be able to change the colors in AM Composite.

Reminds me of a time an irate art-director who sent me out at noon for some house pictures, he needed a.s.a.p. I had them developed 1 hr, scanned them as this was 'pre-digital camera' days, and sent them to him. A couple minutes later I get a call and he's furious... 'I wanted night pictures!"

I have to keep that in mind. But in this case it may not have help. Since I had the light on and I needed to have it at night with moon light coming throw the windows.
