Title: gently worn exterior latex paint
Post by: Paul Springer on 2017-07-22, 04:09:05

Im going for exterior latex paint on composite (non-wood/non-rot) board and batten, semi-gloss, slightly worn material, so no wood grain.  New construction so not trying to age the material to harsh.

Used Sigers for the metal roofing.

Comment critique please welcome on this and overall other.

Thanks in advance!

(Original Serenbe Farms House, GA, USA as inspiration) personal project

I guess you nailed it. I like the lighting and its mood !
Maybe a few clouds in the sky ? (But depends on the style/ look your after...)

This is PG1714 clear sky, i agree needs some sky interest in this case.

Question, Do you have any trick for alpha masking tops of trees, esp when leaf transparency ( sky replace in PS).   Seems like a lot of residual fog/ blurred/light areas around tree tops to deal with.   Contrast adj of the mask gets it worse.

If you're looking for interesting Skydomes, I can recommend the VizPark Skydome Collection.

I think I understand the problem, so you get a white frame around the leafs of the trees, which is caused by the alpha of the rendering ?

Okay, are your leaf-alpha-maps semi-transparent ?
if they are, try to dither them, if not try to shrink the mask in PS and see if this helps...

In which Image-Format do you save your renders ?

After studying, DOF and any leaves opacity creates havoc on the alpha layer, had to go in and do a good manual mask for the sky swap.

Not done it in Corona, but guessing it will be the same as with VRay.. if you render with black background it stops the haloing around the trees for replacing the sky
