FG Interpolation Method (I always need to use it now)

Hi All,

A new problem i've just encountered with Final Father....
All of a sudden, everytime i render i get large white circles and bright areas within my render.

Nothing has changed with my rendering techniques, my lighting or the sizes of the render. nothing.

If i untick the "final gather" option in the render setup box no white circles etc are to be seen. but as soon as final gather is used they show back up again.
the only way to get around this at the moment is for me to tick the "Use Radius Interpolation Method" which gives great results but they take forever to render.
please please let there be a hero out there who knows of this problem! haha.. i'm at my wits end trying to figure it out!

i'm using 3d max design 2009.

Thank you.

Welcome on board Petekillboy,
you know the best way is to zip the max file or a portion of it and post it here. Someone will take a look and give you a suggestion.

Thank you,
i've attached an archive zip file of the model. however it's with every model i create so it's not just this model alone.
i've gone into older models and rendered them and they are fine!

let me know any comments.. thank you 🙂

i've figured it out!!!! and rewarded myself with two sugars in the coffee.
anyhow if anybody else gets this problem.. my solution is:

check your final gather map file you save it to! simple. the file i used was corrupt and would render it with the circles, bright lights, spots, "damp patches" etc..
as soon as i saved it to another file it's gone!
my life is saved 🙂

hope this helps anyone at some point 🙂

Yes, no problems here.
My first idea was that the FG map was corrupt; therefore I rendered the file without it (FG map) and got that image. (See Attachment) During the rendering I got the notification E-mail that you found the solution.

Hi,
thank you for the reply anyway, much appreciated.
this has never happened before in all the time I've used the FG Map so I was lucky to find the solution! it just so happened a previous model which worked, the map was saved to my local computer rather than the server, which gave me the inkling it was the FG Map.

Again thank you 🙂

It looks like photon mapping "issue". Can you show your caustics and GI settings in Global Illumination window?

Also, are you using mr Sky Portals outside your windows to get the Sunlight in?

Looks like you haven't created sky portals in windows. You definitely should do so.

This is what I get with the skyportals.... I've set them to 0.01, but they're still so bright... also the floor is grainy...and it should be a little bit shiny... I also made a render in the same file the only difference is, with that one I used another camera from another angle.., without all those weird spots... I also attached this render, so that you can see how the render should become... Hope you can help me, would be awesome:)

You should adjust exposure instead of lowering portals multiplier. Maybe try to set higher final gather noise filtering.

If you could remove all furniture from your scene and attach it here, i could look at it and try to figure where the problem is.

Many file types will not attach - simply Zip them (not alternatives like 7zip or winrar - just zip) then they will attach.

Max 2016 (SP1/EXT1)
Win7Pro x64 (SP1). i5-3570K @ 4.4GHz, 8Gb Ram, DX11.
nVidia GTX760 (2GB) (Driver 430.86).

Well, there isn't lights, render setups, materials in 3ds file. How i supposed to see where the problem is? You should export and attach max scene without textures.
