Hello,Kostas Mavrommatis student from greece,new to z-brush.Trouble rendering with softimage|xsi,just cant get the detail from z-brush when rendering displacement in xsi,any tips please?
Hello!My name is Kostas Mavromatis,student from greece,new to z-brush,terrific thread rray,would you have an xsi rendertree detailed example?i just seem to do something wrong!!!thanx in advance
Hi Everyone. This was a quickish test done with the new Rio version of Brazil RS for Max 6. Having problems with the hair and high frequency detail in the flesh although I canât tell so far if people are using bumps for that. Sorry the pic isnât a bit bigger but those are the limitations of the demo.
If anyone is still reading this thread and wants to see an extreme close up then reply and Iâll upload one with all the stats etc.

Import obj file. As one previous Houdini user pointed out, the file extension must be in lower case so rename it from OBJ to obj.
Scale the model down to about 1/100th of itâs original size to avoid shadow bias problems.
Apply the shader and set the model to âRender As Subdivison Surfacesâ in the object render parameters. You can also set the displace boound and turn up the shading quality if desired.

I opend the texture file in Photoshop - under image i used Auto contrast to bring the value to black and white
change the mode to RGB and save as to a new texture file
now you have the option to flip it or do it in maya , I just done it in maya
Maya
import the Obj
Rotate it 90 on the X
in the hyper shader apply a new texture and use the displacment mamp that you just created (the RGB one MR will give an error if you use the orginal one)
in the color balance of the texture file I used the following
Alpha gain 1.670
Alpha offset -0.865
As for the object
get the Att Editor and under displacment map
turn of feature displacment
and under tesselation make it 4
i took it a littel bet further and used SSS shader and htats what i got

Iâm a new member and Iâve been watching the results that Zbrush produces with displacement maps , Iâve tried to download your head sample , but the second it finishes , it immediately opens dreamweaver with text nonsense, do you know what can I do ? so I can experiment with your object and lightwave on a mac.
Thank you.
Is this THread a dead-born child?
Where are reactions from the threadstarter about this nice thread?
Or is there a Plugin out with the 3D-App export ??
Hi, administrator: Do you know how can I download your head files? I downloaded a zip file but the result is that dreamweaver opens it immediately and displays only the code text⌠Iâm using a mac and explorer, and pretend to test your models along with the displacement maps in lightwave 7.O, so Do you know how can I convert this files , or is there another link to download them.
Thank You
Hello Ruy,
The problem is that when you installed Dreamweaver, you allowed it to change the setting for zip files so that Dreamweaver opens them instead of WinZip or Stuffit. The particular steps that you need to do at this point are different depending upon whether youâre a PC or Mac user.
If youâre a PC user, right-click on the link and choose âSave Target Asâ. Then specify a location for the file to be saved to. After it has downloaded, go to that location and right-click on it. Choose the âOpen Withâ option and âChoose Program.â In the list that pops up, youâll be able to find WinZip (if you have WinZip installed). Select that, and also check the box to always use this program. From then on, this problem will be solved.
If youâre a Mac user, you should click and hold on the link, then choose âDownload Link to Diskâ from the dialogue. Then you can open it using Stuffit Expander.
Hi guys, I just learnt about the wonders of Displacement and Normal mapping from the Unreal Engine 3 demos. So Iâm thrilled to learn ZBrush might be able to give me these effects shoould I ever start an Unreal 3 Mod. I also have Poser 5 and I want to eventually sell poser stuff online, so I thought Iâd strat there.
Hereâs my Poser 5 renderâŚ
Here are the settings I used in PoserâŚ
Now I tweaked the map in Photoshop - inverted its colour, flipped it vertically and upped the contrast to about 75%. Hope this gives a good starting point for other Poser artists trying to make this work.
I donât like the guyâs ears in my render⌠And thereâs just a smidge of banding creeping in on his shoulder. Canât wait to see how this looks with a texture as well as displacement.
Thank you ,I was able to download the model and the 16 bit map.
Now the question , I flipped verticaly the image in photoshop and saved it as a 16 bit grayscale tif , but lightwave canât open the new file from photoshop , any suggestions? I also convert it to rgb and had no results, I used it as a bmp but the displacement only makes the image bigger or smallerâŚ

Sorry ,know very little of Lightwave, but those posts explained a lot to me.
I rendered both with Max native displace and V ray .With V Ray , had to
convert to Edit Poly and used extremely low Amount and Shift values(less than 0,3. Well, Max dispacement is maybe less acurate ,didn´t try with 4x Meshsmooth, however.Surprise to me is Default Scanline renderer and display
combination rocks.The fastest.
But had to struglle to get Vray better results.
Regards

This image is the frustrating result. Had to smooth it in lightwave modeler and apply the shadows as a texture. Lightwaveâs manual on displacement textures only covers half a page from a total of a thousand pages all over the book , and even in that case it doesnât has a tutorial on how to use it accurately . Iâve revied the lightwave posts and tried them all.
Sorry , maybe I need an upgrade or something .

you need 7.5 I think. You also need to down load a plugin that is free from a third party forget the
name but it works were the built in one seems to fail. go to flay.com and do a search
for a displacement plugin or go to the newtek forum and do a search. I know personally it works as I
have done four different model displacements with zbrush into lightwave 7.5c-d and 8 mac. You need
to convert the 16 bit gray scale to 8 bit gray scale to use it on the mac. You loose some detail but
usually its not bad.
hope this helps

Why do you need to convert it to 8 bit on the Mac? Is that a LW specific thing?
actually lightwave doesnât handle 16bit grey scale tiffs but someone has written a plugin so it imports
them for the pc. the code is available but no one has made a mac version. so there is a way, it
just hasnât had anyone to make it available on the mac. but natively the answer is no, it doesnât support
them on the pc or the mac. I am not sure it uses the extra data anyway. Lightwave is a little behind
in this regard. It does work well though, donât get me wrong. I wouldnât have bought zbrush without
testing it in lightwave first.

Hello strongarm,
Please check out this thread: http://www.zbrushcentral.com/zbc/showthread.php?p=173134#post173134 It contains a complete tutorial for getting great results in LightWave using the Lynx plugin.
FYI: This thread is also linked to from the FAQ>Other Apps>LightWave section here at ZBC. There is more info there for you, as well.
Thanks for the info but again its a pc only lightwave plugin. If your on a mac and lightwave
you have to convert to 8bit grey scale to get displacement maps to work. I wish it wasnât that way but until some
one compiles the 16bit tiff loader for the mac its only for the pc. they come in as garballed garabage
and donât work unless you convert them before hand. Until the mac version of zbrush 2 is released
witch is suppose to be now, you really didnât need this plugin but its becoming very important. I can
get by with 8bit for now. It works well enough but this is important info for mac people upgrading.
thanks again for posting the links as I had forgotten were I had picked them up.

Is the source code available?, and do you need a LW dev kit to compile it?
[edit]
I checked it out. It looks like more work than itâs worth. There is no source code for the âloaderâ if thatâs what it is. But there is the libtiff library which I have used a few times.
Hi all can anyone tell me the settings for max6 final render plugin?

or I have to do something in the render window options Thans all for the help:lol:
