your lighting is fabulous. Can you tell us more about that?

oh.... and are you using zyl UV or σφαιρικός UV

;D

important is to be taken up the photos light-neutrally.
a phototexture is simpler to provide than painted an even.
that secreteat is the combination of effectively geometry
and light-neutrally repainted phototextures with PS.

that means which I remove in PS the light information from phototexture
and make bump and other maps from photo.(spec,diff,etc.pp)
then you can redefine into LW the "situation of light/lightsituation".

you can either a determine situation in the texture paint or however over that light up in lightwave regulate.

UV zyl is UV cyl ...LOL thus "ZYLindrisch in german" and "CYLindrical in english"

sorry

Could you elaborate on how you remove light information with PhotoShop?
If you have a link to a tutorial - that would be great.


really terrific stuff. :D

rene, are you doing that with the usual lab/lightness channel work in photoshop or is there a trick to do so directly in LW image editor? btw. very nice composition...

greg, there is a really nice set of tips to do so here:

http://leigh.cgcommunity.com/tutorials.htm

look inside the last PDF.

she wrote also a very good book "lightwave 8 texturing"... - recommendable!

@all...sorry the following is in german..

@marcus

Das wirklich wichtigste ist Texturdaten zu erzeugen die sehr gleichmässige Lichtinformationen beinhalten.Sprich das abzufotografierende Objekt
sollte vor dem fotografieren möglichst so vorbereitet werden das nur
"diffuse" Lichtinformationen während des Photografierens einfallen.
Beispiel>
Jedes Objekt hat auch in der Natur Oberflächeneigenschaften.
Diese Eigenschaften wie z.b.bei Früchten welche in den meisten Fällen
eine leicht reflektierende Patina haben bewirken das diese Oberfläche
die Lichtquelle mit welcher Sie beleutet werden bündeln und somit ein
Highlight hinterlassen (Sonne,Spotlicht etc.pp erzeugen z.b.solche HotSpots
an gesammeltem Licht auf einem Objekt)
Um dies zu vermeiden (denn gerade das musst Du hinterher um die Texture Lichtneutral zu bekommen in z.b PS entfernen )
sollte jedes Objekt einem von allen Seiten möglichst gleichmässigem Licht
ausgesetzt werden.
Die beste Situation für eine Lichtneutrale Texture ist z.b.ein bewölkter Himmel oder eine gleichwertig simulierte Studiosituation.(so wie es Photografen halt auch machen wenn sie ein objekt ausleuchten)
Es werden nur "indirekte" Lichtinformationen die "breit gestreut" sind auf das Objekt abgefeuert.Somit ist eine Lichtsituation beim abfotografieren des Objektes gegeben die keine direkt sichtbaren linearen Lichtquellen auf dem
Objekt hinterlässt.
Manchmal entstehen bei diesem Prozess jedoch "Artefakte" also Du findest
trotz bester Bemühungen beim abfotografieren & beleuchten unter oben genannten Parametern immer noch Lichtinformationen in dem Photo der von Dir gewünschtenTexture.
In diesem Falle versuche ich mit den Werkzeugen von PS diese Lichtinformationen (z.b.highlights,) rauszupainten bzw. besser gesagt zu
löschen.DAbei gibt es verschiedene Wege welche aber jedesmal anders sein
können je nach beschafffenheit des Objektes.Daher kann ich jedenfalls
bis dato den "Prozess" nicht in Form eines z.b.Tutorials katalogisieren.
Es hängt also vieles schon davon ab unter welchen Lichtbedingungen
Du das Objekt oder Parts davon abfotografierst.
Ich hoffe das war halbwegs >erhellend<.

rene, thanx for the info... for our non-german speaking readers i may VERY freely and synthetically translate:

the important thing is to create textures containing possibly 'regular' lighting information. to do so there are several ways and no 'trick' for all situations. the task is to eliminate the typical specular/ highlights on the surfaces of objects in your texture.
in the case you are taking photos with a camera, use diffuse light where possible. outdoors, take the photos when the sky is covered, in studio use diffusors.
the remaining artifacts on your photos or textures have to be removed in photoshop with different kind of procedures (see tutorials in my own previous post)...

hope this helps :)

Thanks to you both. great links too.

safarifx - your stuff is terrific. There is a "Best of LW" book being compiled.
You should submit some of your stuff to be included.

Looking forward to seeing your next render.
