New interior and problems

[ebad]

Hi all!

This is my new interior and is in progress...

I made the curtain but i dont like that! I think the material has some problems.

I used a standard with opacity of ~ 80.

May you help me to find a good solution?

[blade911]

hey there

 

nice work my friend.

im sortof a begineer so cant comment much. but ur background seems a bit too flat.

 

maybe u cud give the curtains a bend to make it better?

 

alrite then

 

cheers

In this one i limited the windows and used IES Sun.

May any one show me some bluePrints of sofas on the web please?

[richmondlu]

i would stick with the first one.

On the curtians i would fold them a bit and then up the irredesance a bit to give them a little glow from the sun here is a quick test for you.

[ebad]

Thank your dear Sir!

But my curtain has folds just like yours..Sorry i didnt understand "Up the 'irredesance'."!! Can you help about the material please?

[NOOXY]

like the first image but i would change the background..dosn't seem to match the scene...IMO:cool:

Sorry man,

I am a Maya user dont know what you use? Specular, irredesance, incancesance?

Let me know i will try to help out,

been a while on max but will try to help.

Go with the first. Some modeling improvements on the curtains would help, but I believe this may be a perfect opportunity to play with the new Vray 2-sided material. You can give it your desired opacity in the refraction while giving it a slight translucent effect. Give it a shot an let us know.

[ebad]

Thanks

you mean i use a refracting mat exempt of the low opacity one?

Whit a Two sided Vray material?

 

sure i'l test it.

But now i made a new one:

[Tim Saunders]

Ya, with vray materials you adjust the transparency amount by changing the refraction amount by adjusting how white or black the colored box is. Totally black is fully opaque, pure white is fully transparent. I just figured sinse you are using the new v-ray, you should take advantage of it. The new spot3d help files outline how to use the new materials, but that 2-sidded material would be perfect for those curtains if you decide you want them back in your scene.

[ebad]

Thanks a lot Dear Tim!

I'll check it sure! and submit it here as soon as possible and looking forward to see your feedbacks.

[ebad]

By the way...

Can any one help me to understand these new color mapping types:

Intensity exponential

HSV Exponential

And

Exponential

I used Exponential in all off these works.

May some body help about usages please?

It seems like you are missing this great resource: http://www.spot3d.com/vray/help/150R1/

Funny, I had a long discussion in the office about the fact that Vray discribes opacity as refraction. Why? opacity isnt refraction, refraction is the distortion of light ie IOR. Had me confused for a long time

It's an easy misunderstanding, but my last comments on the subject are that refraction is more about how light passes through surfaces than the distortion of light. The amount of "distortion of light" has to do with the IOR. Two separate values there (even though the IOR adjustment is controlled within the refraction parameters). So it actually makes sense that a material that is more transparent would have more light pass through it, thus adjusting your refraction amount. Sorry ebad for the slight diversion.

[ebad]

Thank you dear Tim Saunders.

I welcome to your nice and gr8 ideas.

Hi again ! Before continue about the curtain i've made a new render with LWF method.

Gamma correction for color mapping and IRR and Light cache...

I'm new in LWF and dont like this picture at all...

[ebad]

Here i tested a new scene...

I put a curtain here with this material but there was problems in curtain and all scene was noisy.. I didnt save any one :(.

Standard material:

opacity: ~ 50

Reflection : Vray map (Reflect -Reflect on back side checked) = 30

and one time with Vray material:

Refraction value : 50

Index of Refraction : 1.0

But i faced with the same result.

Lets see.. My light sources are behind of the curtain.Is there any problem with lights.Do you like i make a render with this tragedy?

What do you see about these pictures with no curtain?

THX.

[ebad]

Hey i made it...

I dont know what was the problem i just deleted the windows glass.

My window's glass was some things like the Vray curtain material i described below.

One question remains to be answered:

What could be the glass material? I like have some reflection of room on the window's glass.

Thanks a lot for your attention.

 

The Standard material for curtain in the left side:

Diffuse color : full white.

Spec level : 30

Glossiness : 10

soften : 0.5

Opacity : 60

Vray map with no 'reflect on back side' checked, assigned to the reflection slut arround 25.

The VRay material for the curtain in right side:

Diffuse color : Full white.

Reflection color value:15

Refl.glossiness : 0.6

subdives : 3

Refract color value:171

Index of refract : 1.0

No Translucent checked.

Ward Shader.

[Tim Saunders]

Coming along ebad. Strange stuff about your glass. Can't you just make it not cast shadows and still get reflections? I've got to jump bak on the curtains though. Doesn't your version of vray feature a vray 2 sided material? If so, try it out. It's not just a vray material, it's specific for stuff like this.

[ebad]

Yea..I've it,but what should i use as front and back stuff? Are'nt they some thing like mine?

About the glass;

You mean,turn off cast shadowing in glass properties (Rendering Control part)?

I'm testing...

THX.

[ebad]

I'm Heared your advises;

Used the VRay2Sided material for the curtains in the first picture.

No back material.

One vray mtl for front material with default settings and double sided turned off.

The translucency remains 0.5

The render time increased (About double).

By the way,About the window's glass I used a standard material with low opacity and vray map for reflection slut and cast shadowing turned off for glass object.

The result looks better but i'm not sure.

May you keep on your helps please?

Thx

[ebad]

Any more comments?

[Tim Saunders]

Yeah, I think your getting it. I like the second one better. That very subtle reflectin helps. There may be just a little bit too much translucency going on with the curtain, but that looks much better than before. I'm not sure how walls are made in Iran, but I have never seen walls that bumpy. Also the camera angle is really high. It's probably best if you place the camera about eye level, not level with the fan. Good work.

[ebad]

Thanks dear Tim.

Be sure about walls they are not nowhere and i've edited it.

But just one important point:

I feel this kind of material has no good relation with light cache..

The progress time for it increased about 55 min with the same settings when the last one with out curtain was arround 10 - 15 min.

Also the IRR progress increased arround 2 times.

Totally ~3 hours for progress before rendering (1400 * 1050)

I'l attach the new render once it finished.

Thx.
