Question: How to create bump (normal or displace maps) as in 3dMax ?

[verb]

Ok, friends, I’m gonna slightly mad
Could somebody please help me with displacement (or normap mapping) ? I want to bump some tool like in 3D max without using texture, just material and bump - > it is leather. But then, maybe, I want to paint on it too. Zbrush did not work only with displacement - > only when Texture is ON.

…after 5 minutes …

I think I found the way through using button ApplyDispMap (first of all I made some disp.map from leather texture and imported it in Zbrush), but ! - after applying DispMap (to fix it for then to off texture, cause displacement don’t work without it as I mentioned erlier) the displace, unfortunately, tiles as 1 on 1). !! One more problem ) Please help !

Just from looking at your screen shots it looks like your final model may not have enough polys to support all of the detail in your extremely detailed displacement map. How many polys does your cube have? maybe try sub dividing it a few more times and trying it again.

Thank you for the reply, --E-- !
Yeah… I’m repeat all procedure once again and now my cube has about 2 kk polygons. PLs, see screen below.
One question troubles me: Do I do this procedure wright ? Because I think of it by myself. Is the idea of bump in Zbrush is wright ? (I want to do my works only in Zbrush) - I like it because of its creative approach and instruments not like in 3DS Max - as programme of vertex and polygons :p).

I think what you are looking for is to turn Disp On, set the intesnity to something like .1 and leave mode turned off. that will basically make your alpha a “bump” map inside of zbrush.

Not exactly what I mean. You see - your bump is tiled as 1x1. I wanna fix it, e.g. 5x5, and then paint on it by RGB.

On this moment I didnt fid the solution about the bumping on the tool in Zbrush. But in the process of sculpting I find some strange Zbrush behavior.
Please see it:

First of all I have a map on my tool (it is wood).
Once I open my tool and saw this !!!

How was it made - I DONT KNOW !!! But it is that I want to do aware. You see - only one button is ON - Textrure. But instead of texture - u can see the BUMP !!!

When this button is OFF - there is nothing!

Several times I clicked the button ON-OFF and after it texture is ON but no more bump.

I think, this is amazing !

SOMEBODY, please help me to understand how bump (whith UVs) is working !

It looks like what you did was you loaded the “bumpviewermaterial” with this material on you don’t need to have an alpha loaded as a displacement/bump map. You can just use your texture as a bump. I kind of doubt that this is the desired effect that you are looking for though because you HAVE to use the bumpviewermaterial to get this outcome.

Anyway, to change your tilling on your UV’s to be 5x5 instead of 1x1 just got to “Tool > UV > Hrepeart and Vrepeat” and change those numbers from 1 x 1 to 5 x 5.

and you will get 5 times tiling on your UV’s.

Many thanks!
But could I fix this bump in Zbrush as geometry deformation ?

[eblondin]

Yeah…

1. Convert your texture into an alpha “Texture > Make Alpha”. This will be your displacement map that you will use to deform your geometry.
2. Load the newly created alpha in the tool’s displacement slot. “Tool > Displacement map”
3. Load any texture you want into your tool’s texture slot. “Tool > Texture map”, you have to have something loaded here, it can be a blank texture if you want.
4. Make sure “Tool > Displacement Map > Disp On” is turned on.
5. Turn on “Mode” under “Tool > Displacement Map > Mode”. With Mode on, you will actually be displacing your geometry, with mode off your alpha will be acting just be a bump map.
6. Set the Intensity to something around “.1” (depending on the scale of your tool) under “Tool > Displacement Map > Intensity”. This will act as a preview of what your displacement will be like after you hit “Apply DisMap”.
7. Make sure your tool has enough polys to support the type of deformation that you are trying to replicate via the alpha map (See your first post in this thread).
8. Hit “Apply DispMap” under “Tool > Displacement Map > Apply DispMap”

That should deform your geometry via your alpha.

–E--

It is really great, thank you ! But, unfortunately, we return to my 1st post. There is no TILING to this bump. After “Mode” and Apply -> tiling goes to the 1st tile level small_orange_diamondsmall_orange_diamond. What do you think about ?

Ok, I found another way, but dont know is it wright:

1. Convert your texture into an alpha “Texture > Make Alpha”. This will be your displacement map that you will use to deform your geometry.1.1. Modify your Alpha in Alpha palette: TILE, AlphaAdjust etc.
   1.2. Push the button “Make Modified Alpha” and you’ll see new “baked” Alpha texture with your settings. It will have automatically named (sry for my EN).
2. Load the newly created alpha in the tool’s displacement slot. “Tool > Displacement map”
3. Load any texture you want into your tool’s texture slot. “Tool > Texture map”, you have to have something loaded here, it can be a blank texture if you want.
4. Make sure “Tool > Displacement Map > Disp On” is turned on.
5. Turn on “Mode” under “Tool > Displacement Map > Mode”. With Mode on, you will actually be displacing your geometry, with mode off your alpha will be acting just be a bump map.
6. Set the Intensity to something around “.1” (depending on the scale of your tool) under “Tool > Displacement Map > Intensity”. This will act as a preview of what your displacement will be like after you hit “Apply DisMap”.
7. Make sure your tool has enough polys to support the type of deformation that you are trying to replicate via the alpha map (See your first post in this thread).
8. Hit “Apply DispMap” under “Tool > Displacement Map > Apply DispMap”

Interesting, that seems like a bug to me, when you adjust the UV’s under “Tool > UV Map > Hrpeat and Vrepeat” it should hold all the way through to “Apply DisMap” but it doesn’t.

Your method does appear to work though, manually tiling the Alpha texture instead of the tiling the UVs. good job!

Yes, it have to be bug. And it is our joint work, –E-- ! Thank you!
