¿How do I fix this Disaster?

Yes, I know that there are reversed faces. But look, these "ghost lights"...

I made it under Kerkythea, perhaps I should ask this in Kerkythea forums. I believe that there are not "holes" in the model... I don't know what to do

Gaieus · 22 Dec 2007, 10:57

What lights did you apply at all?
(in Kerky, back faces cannot get any material except for thin glass)

pichuneke · 22 Dec 2007, 11:15

I didnt' modify anything in kerkythea, I am a newbie with that program.

So it's an isue with kerkythea, Am I right?

Respect to orient/reversed faces, I suposse I must modify every single surface and give it a texture. I'll do it when I finish.

Gaieus · 22 Dec 2007, 11:16

Better earlier than later I think. The more you have the more you'll need to reverse!

pichuneke · 22 Dec 2007, 11:25

I am examining it, and I see that al the component has a texture, not "A face, a texture". Or something like that.

Must I begin to define every single face?

Gaieus · 22 Dec 2007, 11:29

Go to monochrome rendering mode to see whether you have front or back faces.
If they are components, even better; enter a component's context, select all the back faces and reverse them. All other instances will change along. Now use the material (again, on the front face) to paint it.

It does not matter whether you apply a material / texture on a back face; back faces are not good either way.

I oriented the faces in the inma cavea, (the blue area) and the problem persists:

I suposse it's a problem of materials in Kerkythea... I don't know

Pichu...
which render preset are u using??? try to use Photonmap medium + aa 0.3 preset.
lower presets can cause light leaks like the ones u showed here...
also try using the path tracing progressive preset if ur using just the physical sky.. takes longer time to render though.. i would suggest it only for the final images.

pichuneke · 22 Dec 2007, 15:31

My settings:

jenujacob · 22 Dec 2007, 15:46

i assume u havnt made any changes in the materials???
i guess u better post this in the KT forum....

pichuneke · 22 Dec 2007, 15:54

Yes, I didn't make any changes to materials. I have no idea about this

I am looking for a solution in Google. As my english and knowledge are limited, I didn't know that the key word was "light leak". If I can't find anything, I will post my problem in Kerkythea Forums.

pichuneke · 23 Dec 2007, 15:26

Now I know that is a bug, but is not my fault. The light leaks appear under Photon Map mode, not with the others.

The images below show you what I say, under different presets.

PHOTON MAP FINE + AA 0.3

PHOTON MAP FINE + CAUSTICS + AA 0.3

RAY TRACING HIGH + AA 0.3

PATH TRACING HIGH + AA 0.3

After doing a quick test, Metropolis Light Transport seems to work well, too.

So now I am not nervous, and I know that I can continue with my work. I was doing it well.

I have tried to start a chorintian capital, that's what I have done untill now:

I used a photo of a capital (Gaeius, you know what I am talking about ).

I drew the figure over a photograph, and then I did something like a tutorial I can't find now, I used intersections to make it. And then I adjusted it manually.

The size now is 147 kb, but the photo is 55 ,kb. I believe I can use 500 kb for the entire capital.

pichuneke · 4 Jan 2008, 10:06

This is the actual situation of the capital:

about 230 kb

pichuneke · 5 Jan 2008, 16:53

About 290 kb:

pichuneke · 7 Jan 2008, 00:26

A render of the capital. It is almost finished, I have to work on some details yet.

The size is 371 kb at the moment

Gaieus · 7 Jan 2008, 01:43

And you were asking for tutorials on this!

Great job, really (just keep in mind to put these on a hidden layer while modelling).

pichuneke · 7 Jan 2008, 10:17

Well...

"Do or do not. There is not "try""

Gaieus · 7 Jan 2008, 10:57

I've put together a couple of types of the Ionic order (more or less complete) but haven't been able to create "easy-to-follow" tutorials from them yet.
They require external plugins (ruby scripts).

pichuneke · 7 Jan 2008, 11:06

Ionic Order is easier than corinthian, so I am not afraid now

If you are interested, when I finish the capitals I upload them here as an attachement.

I believe that today I will finish the corinthian column. And then I will have for my first time the known problem of "I want to replace this old component for this new one in the same geometrical position". I believe that is a classic...

Edit: the exact Ionic capital I need is "Italic Ionic". A friend of mine (the other model I told you) is looking for information about it.
