got it, thanks!

Hmm one final question should do me for awhile.

How do I get my characters’ spec maps to show in a lux render?

EDIT

Ok and a second final question lol.

I just exported a clothed character to lux. His hair is textured in the render, but SOME of his clothes are blank white! others are textured.

I turned on “collect textures” but no dice.

I am assuming you mean after converting to a Lux material like glossy-translucent.  They should show just by putting them in the spec color channel, make sure you have a color no lower than mid gray (128,128,128) and not pure white.  Then, adjust the roughness to between .20 and .40 depending on how shiny you want the skin.  Also, if your bump map is too high, the spec will not show and it will look like sandpaper.

If you are just talking about auto-converted materials, then you usually have to lower the specular strength to about 25% (this is in the DAZ materials section)

No, im talking about skin maps on people. I dont see any of their spec showing up on their skin in the renders. Usually, in 3delight, id add a light with spec only on it but how do I handle this in lux?

notice his pants are textured but his jewelry is appearing white. Also, he should have a specular sheen on his body that isnt showing up

Check that the things ‘turning white’ do not have ‘procedural shaders’ applied to them in Daz Studio - pretty much anything beyond the in-built DAZ standard shaders and the various Uber* shaders will cause any of the non-3Delight render engines to ‘ignore’ them with the effect they tend to render as plain white and without texture.

nope, just plain old texture maps.

Have you used Luxus materials for the jewelry or leaving them as ‘auto-convert’ with the supplied Daz Studio materials?  If the former make sure you also check the ‘copy Daz materials’ box on the Luxus surface application dialog (and double check the diffuse, at least, has been copied across).  If not, check the glossiness and ambient settings.  What item are they, if I have them I’ll give them a try out.

Under Specular color on some materials you can apply a texture. Simply plug in the specular map there and you’ll get the desired effect. Though, note that even with specular maps you’ll want to tone down the specular, ideally no more than about a grey value of 64 all over. That’s because Lux deals in more realistic terms, and a very white area can give very unnatural results, since it controls the amount of light the object is reflecting.

Compatible materials include:

Carpaint
Cloth
Glossy
Glossy Translucent
Shiny Metal

Strange - can’t see the jewelry props/figures listed on that!  In any event I don’t have them so can’t help by trying them out, sorry.

oh wait, they just used them in the promo. As i recall I had to write to that artist and ask what product he used and then found it; I dont even remember which it was, sadly. At any rate, it seems odd they come out white instead of taking in their texture maps. Hmm

Im talking about skin on people. And, forgive me, but im so new to using lux -where is this specular color menu that Id be applying the texture?

If I ever get lots (it happens a lot!) about who made or what is a product and it’s not immediately obvious from the name I often check the path to the diffuse texture (by using the browse option in the surfaces tab).  That can often give a good idea of the product or who made it; doubtless there are better ways! smile

It’s a “bracelet” from the Giacomo for M4 character set.  It does not load with any textures applied, you have to add them through matpose files.  That said, even with textures applied, they render white in Lux unless you lower the specular color to a dark gray (about 64,64,64) as HeraldOfFire pointed out.
