zbrush 3.1 normal map

[AlkoholikDub]

so when i export model from 3dmax ...do i need to choose quads or tris export..?

[conkerzzz]

This flipping-map-in-photoshop thing has spread like a disease, every other tutorial does this totally unnecessary step. There is a flip button in ZBrush and you can flip it in Max, Jeez :p

I get the same thing as bommalomma2. Doesn't seem like kh24mo prepared this cube a lot before making the normal map.

I love you, thanks for posting this.

[simonthesoccerer]

i thank you so much - i searched for hours and didn't find whats wrong with my normal, till i saw this vid and noticed that i have to flip the map in ps.... thanks!

[Bommalomma2]

WTF am I doing wrong???

Every time I press "create normal map" I just end up with a transparent texture!

Please help! Anyone!

Your UVs are screwed. You probably dont have any at all. to fix up your UVs, first you have to export the simple mesh out of zbrush as an obj file, edit the UVs in another program (such as 3dS Max) and import it into zbrush again to do detail. THEN you can create a normal map to be used in your other program (like 3ds max)

[toastingbread]

im having the same problem, is there any way of sort out the UVs in zbrush?

[u3190]

yes, but if your using the model for games, it will look crap, but oh well for 3DS max it doesn't.

go to Texture -> "Enable UV" if you don't have any UV's. Then click on "AUVTiles" whilst at the lowest subdivision level. then you can do all your normal map crap. If you have any questions just ask.

@u3190

What the fuck are UVs?

[u3190]

@MagnusRulerHardt

Why are you trying to make a normal map when you don't know what UV's are?

Do some research, or find a tutorial.

[MagnusRulerHardt]

@u3190

I don't need to know what UVs are either to make a normal map. I just need to click a few buttons, some "morph"... "remember"... stuff, increase and decrease polycount and I have it.

[MagnusRulerHardt]

@u3190

I know what UVs are. No idea how to map the UVs though.

"Do some research" is fucking annoying, do you know that?

[u3190]

@MagnusRulerHardt

I do realise that it's annoying when people tell you to "do some research" but no one is going to babysit you through a lecture on what UV's are. Sorry but unless you go to uni or buy a tutorial no one is going to help you. I've been modeling for 4 years by my self and I've only just grasped the basic modeling workflow in the past few months. Save yourself some time and download a digital tutors zbrush tutorial from filestube.

[MagnusRulerHardt]

@u3190

I never expected anyone to "babysit me through a lecture on what UVs are". If I really didn't have any clue at all (I was having difficulties because nothing was working out for me) about UVs, "a map of where the texture appears on the model" or something similar would be enough. No babysitting or lecture.

[RDRLRA]

@MagnusRulerHardt Don't worry that guy's obviously a retard. It took me four months to learn, and for the past four days i've been understanding the moddeling workflow.

[MagnusRulerHardt]

@RDRLRA

It took you four months? You spent four months learning this? What I couldn't do after one or two times watching this video, you can do in four months? Congratulations.

[zico81]

must be down to your UVs.

[PSPmaster321]

Nice one. Except. Do I need to lower the reolution on my model to make the normal map??

[Algae998]

yes, youll need to drop down to your lowest sub-d level to generate the normal map.

[u3190]

you need to be on the lowest or a reasonably low Subdiv level. Zbrush then creates the normal map from the highest Subdiv level.

[PSPmaster321]

Ok thanks guys.

I had figured it out =]

[zico81]

yea because the normal map will act in accordance to the number of polygons on the model.

[Blahhhhhhhhh]

I've previously been making my normal maps in max.I got a character I already made a while back that I made normals for in max works fine. But I've been trying to make the normals in ZB and the normals look great but I've found that when I export the map and bring it in to max the renders show certain parts of the model inversed say hands look darker than the rest of the arm. when I make normals in max the normals have an extra alpha in them but these do not. Got any ideas?
