Doom3 doesn't use bump mapping - the worlds are pure polygons with pixel textures... and trust me all of the effects take a hellofalot more coding ability to pull off than this whole forum could musta (sorry if anyone fells offended)

As for the bump mapping, is quite a skilled effect to pull off properly - especially real-time with multiple light sources.

If i were you i would put the thoughs of making advanced effects in the - once the game is complete todo list, and sit down and work on the actual FPS. Even though DBpro now makes it easier than ever to develop one, there is skill alot more coding that goes into them than you'd relise.

Just work on the basic, if in a few months time when there is a demo of your fps out and it plays well - then you can ask again and get a decent answer

Holy jumping mother of god NOOOO!!!...
Ahem I mean, I'll think about it

well you can't do it within bsp direct without making a DLL within C/C++ that can alter the render of the textures once projected onto the bsp world, which would require knowing the render setup within the DBpro DLL which handles the bsp...
Althought Lee would probably be willing to show an example of howto access it, then getting in an bump mapping of this nature would be very tricky and not recommended until DBpro is more stable itself!

However if you develop the world as a form of BSP which is rendered within DBpro itself - then to bump map a surface is quite a simple matter, yet the calculations are complex and very processor consuming

if you really want to achieve it then i'll see about writing up a small demo of bump mapping...
but please make sure you have the rest of the game done and this demo will only help for you to understand how bump mapping works not howto achieve it as a plugin for bsp!

yes please, write a small demo of bump maping in a bsp, we are a small group of people and we buyed dbpro for this feature and the new effects of shadows (vertex and pixels),

please, this effect is "indispensable" for the game that we are planing

Currently it is not possible to set bumpmapping to BSP Level.

alot of people here won't know how bump even works let alone howto help out... please be patient and you won't be disappointed!

i'm not sure how bump mapping can be a premium feature in a game though, it should be used to add realism - nothing else really.
