Always happens to me. My guess is: lightsource position?... Perhaps the gurus could help...
Exterior yan master Erick ahhhh... Post mo ha...

sir maybe wala tlaga effect ung bump mo, bka kulang kc minsan ganun dn sakin panapanahon sobrang kulang ung amount... kc para sakin, parang walang bump ung mat nyo, ngmukha lng meron lahat ng front, orig picture lng tlga... ngaun pgdating sa side ngchange ung angle, kaya makikita mo na na wala tlagang bump...
di ako sure...hehehe

Two things :
1. Check the bump uvw mapping - make sure that the mapping ID is the same as the one in your diffuse.
2. Lighstsource position - bumps won't appear if you do not have specularity and a light hitting it directly, remember that bumps just alter the surface normal direction - there is no topography change.

naencounter ko din to. pansin ko lang, at a certain angle, nagfail na ang bumps. pansinin mo din ang floor mo.
pwedeng solutions are:
1. change angles.
2. displacement maps.
3. modeling.
4. explode and apply maps separately.
Alam ko meron pang solution dito. sana may makatulong. good luck erick.

One way to check no. 1 is to go to the bitmap slot of your bump map and hit the bitmap viewport visibility on. If you see your bump map displayed on the object properly then it's working.

Displace mo na kaya Master Erick?... I'm still stuck with the notion that the light source is the culprit. As I've mentioned palagi ko naeencounter yan di ko nga lang masyado pinapansin na; can't handle any more OCness else I'd be taken to the nearest mental institution...

1. try mo Map scaler kapag hinila mo yung object mo nagbabago X,Y,Z map niya.
2. Or vray displacement laruin mo lang amount and shift niya
hope mkatulong

nangyayari din po ito sakin,,,lalo na kung maliit yung mga bricks or stone na gagamitin mo, pagdating sa side, parang plain finish nalang siya,,di mo na marerecognize ang mga bricks,,,

mind to lessen the blur amount of your bitmap on bitmap coordinates, medyo i-enhance nya ang bitmap.... hope it helps

Here's the original file rendering
The bumps are actually working, this is noticable in the columns since it has no diffuse map, the patterns you see are actually the bumps. The details and bumps on the steps are not noticable because of the way max handles bitmap filtering. There are two solutions that I could think of to make them more prominent; one is to turn off Bitmap Filtering in the Globals parameters and simply let the antialiasing filters (Catmul-Rom as set up by Erick) do its work.
Here it is without Bitmap Filtering:
While it might not be perfect, you can now notice how the bumps on the angles frontal to the cameras look better than with Bitmap Filtering. This can be further improved by adding a bit of specularity. Like Standard mats, you will not see your bumps if you do not make them specular:
The problem lies not in the absence of bump mapping but by the extreme angle the camera was set. Remember that Max will try to filter the fine bump maps and diffuse maps that Erick was using. The task gets nastier the farther the details move away parallel to the camera. If you try to render the original file from a different view, I am sure that it will be visible. The second way to make them visible is of course thru displacement mapping.
Goodluck.
