Known Issue: ZMapper not using bump maps in calculation.

ZBrush Usage Questions
#1

I have followed the tutorial by Precis of Normal Map Workflow to make my normal map including a bump map in zmapper(zb3.1).After the calculation,I couldn’t found the bump’s effect at the result and it is said “Bump mapping not activated” showed as the picture underneath.what’s wrong with it,thx for any help very much.:+1:

I am investigating this for you.

#3

Thx for your response,aurick.
Waiting for your good news! :slight_smile:

yeah it does that with me too, generated a disp map from tool>displacement activated bump map by altering intensity and depressing mode, then go into zmapper and and try and create normal map but still says bump mapping not activated even though it is definitely there in the alpha palette.

This worked in ZB2 maybe theres a different way of activating a bump map

#5

Still no answer on this? has anyone else had problems incorporating bump into their normal maps or is there an option that has been moved we are missing?

#6

Yeah zmapper seems to be in need of a update to get it back to how it was in zb2.

We need the rolling bump map into normal map fixed.

And the mesh with multiple uv regions not being able to create a normal map at all, fixed.

#7

ah a response :slight_smile: well glad i know now it wasnt something i was missing guess we have to wait till ZB 3.2 or will they fix this prob with just a plugin update?

#8

All I can say is that we are looking at what’s happening. I don’t know what form the solution will take, or its timing.

#9

I’m just having the same problem here as well. I’ve tried different things, but still can’t get my bump map incorporated into the normal map.

I can see everything fine with the bump map material. After the normal map is made with ZMapper, no bump map effects are added.

#10

Has anyone found a solution for this yet ? I’m running into the same problem.

:mad:

#11

Bump…

I would love to know when this will be fixed as well !

cheers

#12

We have confirmed the problem, so it is on the list of things that need to be handled. I don’t have any dates that I can give, though. Just be assured that it’s in the works.

#13

hello Aurick;

I m just in need of the bump into normal map function of the zmapper, in one of the project I’m working on.

If the solution of the problem to the zmapper is not coming soon, could you ,please, give us some other way to achieveing this effect?
kind of a small tutorial… or pointing us into an alternative?

Thanks very much in advance

Emmanuel

A work around is discussed in this thread. Hope this helps…MG

#15

that isnt a workaround that just shows u how to generate a bump from the displacement not integrate the bump into the normal map which has been the problem…but there are apps for converting bump/displacement maps into normal maps like the nvidia photoshop plugin and that free crazybump prog which is pretty handy

#16

second to ‘CrazyBump’ for integration atm… or forever.

Hi guys

Did Zmapper for Z3.1 got a fix.

I am still unable to roll bump map detail in to normal map.

Don’t need any work arounds, but want Zmapper to work as
it does in Z2.

Thanks

waiting for a reply
Is aurix there,

#18

No, the feature is not yet available.

#19

hey, first sorry if i revive an old thread with already a solution.

i just started using zbrush and got the “bump mapping not activated” and “cavity shading not activated” errors. this is about the best of topics i could found about the errors.

so just asking if this is solved by now or do i need to learn (which i will anyway) the displacement map work around suggested in this thread?

would be nice to get zmapper to work.

I’m on a pc using zbrush 3.1 for the bump, max3ds 2009 for the lowpoly modeling and applying the bump map.

any help much appreciated.

In 3.1 you don’t need that feature anymore.

How big is the map that you’re creating? If it’s 1024x1024, that’s about 1 million pixels. If it’s 2048x2048, that’s about 3-4 million usable pixels. If it’s 4096x4096, that’s about 10-12 million usable pixels.

The reason why the bump map capability was included with ZMapper was because ZBrush 2 couldn’t handle the polygon counts to match the pixel resolution of larger maps. But ZBrush 3 can.

Let’s say that your bump map is a 4K map. That’s equal to a 10-12 million poly model. If your model already has that many polys, you’re not going to get any more out of the normal map by using the bump map. It’s impossible.
