Thanks Spheric for answering all of my questions!  I really appreciate it.  One more question for you:

How do I make a floor reflect the objects that are on it?  I’m working on a scene with a checkered floor and a chair.  When I render it, the floor has no reflections regardless of what I set the reflection value to in DS.  I’d like to have the floor reflect the chair as if it was just polished. smile

Thanks again!

P.S.  What do you think of my “Andrea on glowing cube” render from above?

For the floor to reflect, you can turn up glossiness, specular strength, and reflection strength.
Or you can Do Luxus - LuxRender Materials, choose glossy and make sure you adjust roughness very low.  Try 0.001 for U and V or something like that.


In regards to your image, I am pretty braindead when it comes to art so it may not mean much coming from me, but I am impressed.

I thought I would share a render.

I was envious of all the LuxRender images I saw in the Reality ads so I had bought Reality but never really got going with it. Truthfully I never gave it any time to learn.

I then snagged Luxus on sale, as I was still jealous of the lux renders. Can never have too many options.
I found Luxus to be very intuitve and simple to learn, with still enough controls deeper in to gain improvements when it came time to learn.

My first renders were ‘ok’, with my only real complaints being that I struggled getting skin to look decent. I tried mucking around with the Luxus surface setting to no real avail. One day I will sit and try to understand Slosh’s methods, but I am not up to that yet. Still more of a pre-canned surface sort of person.

This is a very quick and simple figure study, but to me looks pretty realistic.

The figure is GND4 Athletic, by Blackhearted.
I added the Dimension Theory Interjection shader
Used the Luxus Sun light, didnt even have to adjust it
and rendered in LuxRender vi Luxux plugin.

Very little twiddling to get it done. Hardest part was getting the clothing to fit as the GND4 body is not included in adjustment morphs in the Beach wear clothing set.

Set DOF in the DAZ Camera

I use the Kodachrome 25 profile, I like the deep vibrant colors it gives and have had the best luck with it doing decent skin tones without having to mess around with the surface settings.

Hey Guys,

I got some issues with the auto-convertion of Hair into LuxRender. Maybe some of you could help. You can reach the thread under http://www.daz3d.com/forums/viewthread/24871/

Kind regards, Nico

Just a quick one, glass table top is glass2 with volume and absorption (Crystal IOR), table legs are metal2 with a chromium freshnel .NK file. The pillows and blanket are LUX velvet.
Modelled in DAZ 4.6, rendered in Luxrender 1.3dev using LUXUS.

Hope you like it.

I usually cheat for reflective surfaces and mix in a little mirror material with the glossy. That way the reflections have far better definition in my opinion. That’s the method I used on my shower image for the tiles, since even reducing the roughness to zero wasn’t giving the best effect.

Wow, thanks for the tip!  I managed to get my reflective floor by lightening up the LuxRender Glossy Specular color.

Spheric, thanks for the compliment.  It does mean a lot!

My displacement maps aren’t showing up.  What’s the trick to it?

Did you remember to check off the box for “Copy Studio Parameters” which will carry over the maps?

The displacement maps are being written to the .lxs file, but no displacement is apparent in the render. If I export the same scene with Reality, the displacement is there.

If I convert to a glossy material, and tick the use DS settings box, the map doesn’t carry forward.

Here’s the material from Luxus using ‘autoconvert’:

#Material: plane.Default

Texture "diffuse_color" "color" "constant"
 "color value" 
[0.04777575 0 0]

Texture 
"disp_value" "float" "imagemap"
 "float vscale" 
[-1]
 
"string filename" ["D:/Textures/Tests/checker.jpg"]

Texture 
"disp_texture0" "float" "subtract"
 "float tex1" 
[1]
 
"float tex2" [-1]

Texture 
"disp_texture1" "float" "scale"
 "texture tex1" 
["disp_texture0"]
 
"texture tex2" ["disp_value"]

Texture 
"disp_texture2" "float" "add"
 "texture tex1" 
["disp_texture1"]
 
"float tex2" [-1]

Texture 
"disp_texture3" "float" "scale"
 "texture tex1" 
["disp_texture2"]
 
"float tex2" [0.01]

MakeNamedMaterial 
"material0"
 "string type" 
["glossy"]
 
"texture Kd" ["diffuse_color"]
 
"color Ks" [0.009685717 0.009685717 0.009685717]
 
"float uroughness" [0.8]
 
"float vroughness" [0.8]

NamedMaterial 
"material0" 


Here’s the ‘converted’ material:

#Material: plane.Default

MakeNamedMaterial "material0"
 "color Kd" 
[0.04777575 0 0]
 
"color Ks" [0.02201299 0.02201299 0.02201299]

"float vroughness" [0.1]
 
"color Ka" [0.2195197 0.2195197 0.2195197]
 
"float d" [0]
 
"bool multibounce" ["false"]
 
"string type" ["glossy"]

NamedMaterial

For displacement to work correctly you’ll need some level of subdivision on less polygon intensive objects. You can set this in Luxus and either use micro-displacement or loop. Micro-displacement subdivides and displaces objects during the render, so they take up less memory but it can cause longer render times. Loop subdivision displaces objects before rendering, so they can take up a lot more memory, but it will speed up renders. If you require a high degree of subdivision, it’s recommended you choose micro-displacement.

Thanks HoF, that’s exactly what I needed to know.

(The manual was not very helpful on this point.)

Kodachrome 25 - I have thousands of Kodachrome 25 slides. It was my favorite film, and still is my favorite profile in Lux. I wish there was a Kodachrome 25 setting on my digital SLR! ;-)

That looks really good, rhale.  What hair is that?  Love the messy look.  Very realistic!
