Need HELP - Will PAY!

Community
#1

Ok guys … here is the deal …

I have been at this for two days straight and am missing something small I am sure, but I am up against a deadline and need help getting my models into Max for my VRay renders using displacement, normals, textures, etc.

I have some general questions about the workflow and am willing to pay for your time via phone conversation (can pay with Credit Card, PayPal or send a Check).

If you are seriously interested, speak understandable English and can host or receive a call in the US or Canada let me know and I will get in touch with contact info.

I am sure I can figure this out eventually since I used to use ZBrush for this very thing years ago, but I am rusty, technology has changed, up against a hard deadline and quite simply could use the help.

I estimate the call would take 15 - 30 minutes and I am happy to pay for the call and your time.

Can’t help unfortunately, Maya kid.

But have been where you are and will keep
my fingers crossed for you.

Best of luck, don’t give up.

Edit: not to cheat someone out of money but why don’t you
outline the problem generally. Talented and generous people
hang out here.
Maybe one small suggestion will unravel the thread.

They will undoubably move your thread to the bottom anyway.
Ask there.

Or even wilder, ask support at Pixologic, if it pertains to Zbrush
and another program, they are also very helpful.

I have Maya on order since I am in the process of migrating back to Macintosh after 6 years of nightmares with windows … but it will be months before I am up to speed and will likely always use Max since it was my foundation and I am comfortable with it.

I have built a basic max scene with my test model exported back out of ZBrush and will forward that to whoever gets in touch with me. Also will forward them the ZTool as well so they can walk me through the proper way to do the Displacement map for Max/VRay.

Hi hosch,

Can you post some more details about the issues you’re having difficulty with?

Then we can tell how tough (advanced) of a problem it it.

Regards,
Eric

Zbrush displacement for max2008

screw this up, type the above into search.

Sure:

The main issue is that my tests using a basic noise map (pure black and white) from max works perfectly. Works with negative as well as positive displacement on the model, but when I export the displacement from ZBrush it is in grayscale and effects the entire model since Max uses black/white to displace. This may not sound like a big deal on a sphere, but on a detailed model such as the human heart with small veins sticking off of it it just does not work properly with my current settings at least.

Been though that one already - either I am a rock (entirely possible:) or it is just not working for me for some other reason.

#9

Did you try and use the map as a tiff.
Forgot how to do this,but in Photoshop convert the black and white
image.
Maya used to have problems with displacement maps that
were not tiff.

Forget money in the title,invitation to a waste of time.
Every nut and his cousin will be there.
Try this,formulate the question and put it into troubleshooting.
Trust me, some of the greatest people in the business come here
and sooner or later have hit problems such as yours.
Call or email direct Pixologic.
I would bet next weeks check that you are not the first to
have this problem

#11

Sorry I can’t help hosch.

The only time I rendered displacement maps in Max it took so long to render I gave up.

I use ZBrush generated normal maps and a little higher resolution model rather than bother with displacement maps.

#12

Exporting Displacement Maps To Max From Zbrush 3.1

copy and paste the above into search, it discusses file type.

#13

You might be right - I have only done this one other time - about 4 years ago and got a student to call me that really knew his stuff and it paid off for us both.

I have my entire workflow down for this project other then the Displacement from ZB to 3ds/VRay.

I am a week behind because of computer issues and a bit desperate so willing to put up with a couple of wastes of time if I can weed through to get someone that really can walk me through the proper flow - should be a short call if they know their stuff /shrug.

#14

Terribly sorry could not be of help…
Fingers crossed…

#15

Wow that looked like a promising thread until I noticed that every single link to instructions or walk through posts were broken :(.

#16

Could you post a screenshot with the result that you are getting so we can troubleshot the problem ?

In the vray displacement modifier try to put the Shift value of -(Amount/2) so you will get negative displacement

#17

If they were there, someone besides you has/had the problem.

Ps. Know a little of what you are going through.
A few years ago I wanted to create displacement maps
in Maya.
For three long days and night worked my ass off, no good.
Got to be a compulsive thing, me vs it.
Begged on a thread for help, like a drowning man.
Then a great guy named Scott Spencer ( now world famous author:D )
helped me.
Was doing a lot wrong, not flipping image, not converting.
For months after did one every day so would not forget.
Now, no need to use, forgot again…

#18

Sure will do - I have tried pos and neg values and have had unsatisfactory results each time - still convinced it is <— user error though, LoL.

Give me a few moments and it will be posted.

#19

I’ve attached an example file on how to render the displacement in vray and what seetings to use in zbrush.

Hope it works.

#20

just a basic image of the model in low poly form that I am importing to max - just a basic low poly heart
