how to correct tree leaf glowing edges?

hello CGP... i have here an image that needs a cure... my problem here is actually yung tree edges.. notice that the edges of the tree leaves are somewhat glowing due to the sun intensity.. is there a way to correct this? ignore nyo nalang yung blue background.. sinadya ko para mas makita nyo yung problem. PNG yung perspective image.. di ko tuloy malagyan ng blue sky kasi lumilitaw yung leaf edges na maputi.. sana matulungan nyo ako regarding this problem.. thanks in advance and Godbless.

sir pansin ko lang ano po yung puti na nasa rigth ng image na kasama yung mga trees.kasi na encounter ko na yan yun ang nagbibigay ng liwanag kasi sa trees mo.sana makatulong

check mo yang kay erick galing ng tutorial nyan...

Usually hindi ganyan ang background kung ganyan kalakas ang ilaw mo sa tunay na buhay. Kaya kung blue sky ang ilalagay mo, mapapansin mo na parang mali.

Hindi ko pa nasolve ang problem na yan, pero may trick akong ginagawa dyan. Usually nilalagay ko yun may mga ganyang glow sa area ng clouds para magblend. Kung gusto ko naman blue sky, medyo sa upper portion lang ako naglalagay, yung lower naka almost white na, para magkaimpression na malayo para may depth ang sky.

Kung hindi naman importanting gawing blue ang sky. Gawin mo nalang ang ginagawa ko. Wala naman difference.

yes master bok.. hndi talaga blue sky ang bagay sa jan. gusto ko lang matutunan macontrol yung glowing edges ng leaves kasi madalas kong problem yan master... thanks sa tip master bokkins..

sa lahat ba ng trees na ginagamit mo ganyan? cguro may reflection yung dahon,

thanks zdesign..

That happened when you are saving it in .png format (where you were be able to customize the backgound image such as the sky).

The white color is more apparent in small & thin shape objects such as leaf that located directly with background.

Noticed the foreground vegetation doesn't have that much reflection as compared those in the background. The reason is that the objects in the foreground are calculated or being sampled with their nearby objects.

You can examine your image when imported to photoshop, the outline or edges of the rendered image is white all over with the background.
That's because only the foreground image is sampled without the background (especially when save to PNG).

Try to render it again with your chosen background image ang save it to .tiff or .jpg. You will notice that the white color will be minimize (except for object's reflection) that's beacuse it was sampled along with the BG.

The best solution is to render it with your pre-selected BG in max or in photoshop choose a gradient sky map where the horizon is almost white color as master bokkins told earlier to complement with the white outline of your rendered image.

Another way is to erase the white outline in photoshop but im not recommeding it. Good Luck!

My hunch is that you have the opacity maps in the refraction slot and the white lines may be the refracted bg or maybe the pngs aren't premultiplied.

Nevertheless, I can only offer a good solution once I see the max file and the corresponding textures used in the trees.

my take on this is to match the color of the glow instead and not the other way around. if you notice sa mga realistic renders dito, halos white na ang sky.

hope you dont mind, i did a little experiment. following neil/bokkins' suggestion

its ok celes... actually my final output turns out to be like this.. reason why i posted the problem is what if i darkened the sky although i know blue sky doesnt fit in this scene. just want to gather solution how to control those glowing edges if ever kailanganin ko in my future renderings.. thanks for giving time and effort for this topic celes..

thaks alot master v.. i'll try to post the set-up and teh leaves setting

my version

hehehehehehehe.. thanks sir onel.... stand-by everyone for the sir onel's post... may solution na siya....

What was the solution?

sir v naka flash yung file e.. andun yung link kay render master above..

master v. referring to the solution itself and not the link. WHAT is the solution?
As for render master he give his indirect solution by using another program.

I cannot download executable files, our network dumps them to the bin.

This is exactly what I would like to stress - without knowing the actual cause of the problem then there is no way to cure it.

If tsukoy still got the scene files, please upload them including the textures and I'll try to find a solution.

- what ive done there is just a temporary solution, its just a way kapag wala na talagang choice. i just assume na rendered na ang project, naka .png format na and need ps composition para lagyan ng background.

anyway pdf format here: http://hotfile.com/dl/72257879/b9854e3/glowingedges.pdf.html

this is an interesting thread. and i found this in many areas and usually photoshop is an alternative. all the brains are here working together and i hope tsukoy will no mind sharing his docs to Mr. V (evn by pm) so we could see a possible solution. watch mode " i dont have solution in rendering, but very interested in correcting refracting halos.

you can also defringe tools in photoshop here.
