Hello all and hope your weekend is off to a great start.

Listen I was wondering if someone could help me with a problem?

I have a prop someone made for me and I would like to give it a marror like reflection yet still keep the same basic colors it already has.

I have done a search in the Tutorials forum and found the following tut, but for some reason when I apply it does not work for me. http://www.renderosity.com/mod/tutorial/index.php?tutorial_id=202&page=5

Please look at the background prop on the attached and let me know if any of you can tell me how I might give it a very stron reflection yet keep the same basic colors.

Thanks much

Steel

do you mean on the colored bars or do you mean the floor?

 

You need to make sure that when you render, the raytrace box is checked in your render settings, theres no reason why using that node shouldnt work. ;)

Thanks for replying so quickly Lzy.   Im talking bout the colored bar's.

Oh the picture will be a dedication to Amy Winehouse

You can see were I got the idea for the background set here

Yeah, I liked her, such a shame....

its a good picture :)

You node it correct? You have a reflecting value?

 

BTW, nice Image. I love Amy W.too . Sad she passed away so young :(

Screencap of the material room will help.

render with raytrace on and at least 2 tot 3  Raytrace bounces The node should look like this

Ok Guys Ive tried everything but no go; it still does not reflect.

Also once while looking at a mat or something I saw a node that made it {the mat}very Glossy.

Im thinking if I cant get it to reflect maybe a high gloss might work.

Do any of you know how I might find that node and use it?

Thanks again

Steel


vilters ( ) posted Sat, 03 December 2011 at 1:54 PM

add a screengrab of your shader setup in the mat room
and a screengrab of your render settings..

Pictures can only be 200k

Is that a render you are showing above?
I see no shadows either???

Tip, put ambient on the floor.
Such a floor begs for ambient....

Yes vilters thats a picture of the render I added when first posting this thread.

Im sorry but my knowledge of Posers inner workings is still somewhat limited so not sure what you mean when you say  "Tip, put ambient on the floor. Such a floor begs for ambient".

Can you please explain what you mean???

Thanks


vilters ( ) posted Sat, 03 December 2011 at 2:22 PM

For your floor:
You have an image plugged in diffuse_color right?
Remove the image from the diffuse_color but connect it to ambient_color
And set ambient_value to 1.000, and render.
You can go up in ambient, try 5 or 10.

Still, why are there no shadows anywhere?

But then again what are your render settings?
You sure you render with Raytrace ON?

Reflection is one of those nodes that are not visible in preview.

Give me a few and will send a screen shot of Render Settings and advanced Materail Room settings.

Also the flow is just a basic Poser Glass setting from the materails room.   I turned down the transparancy setting and thats it.


hborre ( ) posted Sat, 03 December 2011 at 2:43 PM

I am beginning to think that the floor has a reflection node with an image map attached.  None of the reflections match the props/characters standing on it.  Also, as vilters mentioned, raytracing should be on for the render settings and visible in raytrace active on all objects in the scene.  For reflections to be successful, you need something in the scene to reflect, like a skydome or surrounding room.

Again, screencaps of material room and render settings will tell alot.

In the example 2 identical laptops (click to enlarge) The left has the screen texture in diffuse_Color

The right one has the same screen texture in ambient_color, (set to white) and ambient_value set at 2

The right laptop is now emitting light as lamps under your floor would also do.

Ok guys dont know if this helps or not but here is a screen print of my settings in the materail room for the background prop


hborre ( ) posted Sat, 03 December 2011 at 7:30 PM

bTW, which Poser version are you using?


Anthanasius ( ) posted Sat, 03 December 2011 at 7:32 PM

ouch ça ça fait mal !!!!!!

Remove the reflect node from the reflexion value.

Set the reflexion node to the defaut values, quality 0.2 softness 0 raybias 0.8.

hborre ( ) posted Sat, 03 December 2011 at 8:29 PM

I am running a quick render right now which is actually taking much longer than anticipated based loosely on your post.  I don't like the numbers on the reflection node either, so I would suggest resetting those value back to default as Anthanasius recommends.  I have also added some modifications to the material which can serve as a starting point.


hborre ( ) posted Sat, 03 December 2011 at 8:47 PM

file_475860.jpg

Hopefully this is what you are striving to achieve.  This is basic Andy2 placed under a skydome with one infinity white light set to raytrace shadows.  No IDL was applied to the render, raytrace bounces set to 2 just to save time. 


hborre ( ) posted Sat, 03 December 2011 at 8:48 PM

file_475861.jpg

This is your material room setup except I changed some things to enhance the effect.

file_475862.jpg

Now, this next image shows the changes that should be incorporated as a starting point to refine the technique.  Note, the diffuse_value is set low to increase reflectivity.  If your desire is to make the material more opaque then increase this value.  I would not recommend pulling it to 100%; that will stall your render time. 

Take the default values for the reflect node, don't modify until you understand exactly what the changes will do.  Also, drop the reflect_value connection, no advantage there. 

Add some sort of specular node to enhance the specular response to your lights. 

Do use raytracing in your lighting and render settings.  I noticed default lights in you screencap, are these lights set to depthmapping or raytracing?  That makes a difference.

Also, do have something to reflect!  Without a background to reflect, your render will either show blackened areas or no reflection at all.

Hey hborre That is exactly what I want, only I was hopeing it would reflect the musicians and equipmet and stuff in front of it.

I will try adding sky dom and see if that wiill give it something to reflect.

also here is screen print of advance materails room when when trying your set up


Steeleyes101 ( ) posted Sat, 03 December 2011 at 9:10 PM

Oh Im useing poser 8 have not installed P9 yet


hborre ( ) posted Sat, 03 December 2011 at 9:15 PM

Just disconnect the Reflection_value node and delete it.  Also reduce the Diffuse_value to something else other than 1.  That determines your opacity of your material.


Steeleyes101 ( ) posted Sat, 03 December 2011 at 9:25 PM

Ok give me a few to try and fully figure out and understand your directions.

Im sorry for taking so long to figure this out but what Im trying to do is something totaly new to me.

Thanks in advanced for all the help and time you are putting into this :)


hborre ( ) posted Sat, 03 December 2011 at 9:50 PM

file_475864.jpg

Here is another render with no skydome involved.  One-sided square place behind Andy, one infinite light, white, to the side.  Intensity set to 75%.  Shadows=60%, shadow blur radius=2, raytrace.  Light angle crucial because of the reflective surface of the square.


hborre ( ) posted Sat, 03 December 2011 at 9:51 PM

file_475865.jpg

Here is the Material Room set up of the square.

There should not be two reflect nodes. That's Reflect * Reflect = Reflect squared. I know you don't understand the math, but you should listen and understand this - that will destroy the reflections. It is math nonsense, and it will produce nothing - it will appear to be not reflecting at all.

Once you get reflections you will find it is really not realistic without a Fresnel effect, but you're not getting anything at all. You don't need an environment or sky dome - won't help if you don't fix the shader.

Setting the color you want in the Diffuse channel is fine if you want a shiny colored dialectric (non-metal) material.

If you want it to look metallic, don't use diffuse at all. Set Diffuse_Value = 0 and put the color you want in the Reflection_Color.

And, again, for serious realism you want to take the Fresnel effect into account. Like this.

Here is a demonstration of the difference between diffuse color and reflection color.

This is all the same color green, but the emphasis goes from diffuse color to reflection color, left to right.

Once again thanks guys for all the help

Now that's progress.


Steeleyes101 ( ) posted Tue, 06 December 2011 at 6:23 PM

Thanks hborre   Now my problem is to keep that simple natural pastel look.   Im thinking the sky dome color might be part of the problem as far as the reflection color, or maybe Im thinking add some textures, but I was really hopeing to keep the same feel as the set in the vid http://www.youtube.com/watch?v=UXAOjgVpQWU  which is where I got the idea for the backgroun; any ideas?


hborre ( ) posted Tue, 06 December 2011 at 7:03 PM

Skydome can influence the color of your prop reflections.  I would try both, or darken the skydome enough so as not to be noticed.
