Hi everyone,

I am trying to add a bump map to a mesh, but so far the modified nifs always crash the game (as well as the construction set).

Here is a link of a screenshot which I took while I was working in NifSkope:

Can anyone tell from this image what I am doing wrong?

The postbox1_n texture is an embossed version of the base texture added using the 'Add Bump Map' function.

Another question: the NiTextureEffect texture is a lens flare. Is this the right kind of image to use for this kind of purpose?

Many thanks in advance,

Swiveller

Thank you for the reply. I am aware of your thread, yet I am afraid that it does not answer my question. Basing myself on the structure of one of the nif files in the Art of War Museum mod, I believed that my nif file contained all of the necessary features. Yet obviously I am doing something wrong as the file crashes my game.

I do hope that someone with more knowledge of how bumpmapping in Morrowind works can take a look at my screenshot.

Have you been able to figure out how precisely to get bump maps to work, Guitarjoe91?

Unfortunately, you nif shows not much (no block details and shifted windows).
I assume that 0 NiNode is a scene root node ? usually NiTextureEffect node is parented to another NiNode: see Bjam's tutorials for adding texture effects in NifScope.

You can look at one of my weapons on PES.

Do you mean that more information is available, A1x2e3l, or do you mean that such details should be added? I have only a basic understanding of the nif file structure.

I have not yet been able to find Bjam's tutorials. Could you please post a link?

Many thanks in advance!

EDIT - I got it to work! Acting on A1x2e3l's suggestion, as well as a comparison of my file with Dragon Lance's Nerevar's Blade, I created a new NiNode subsidiary to Ninode 0, and moved all of the data already present there. The nif now functions properly; no more crashes and the bump map displays as intended.

Problem solved! See the edit of the previous post.

I intend to write a brief tutorial for others facing similar difficulties; will probably post in on PES once finished.

It needs to be part of your environmental map to work. Other wise you'll have a bump but it will never really bump in game... You'll just think it does.

Light should reflect off a bump map for it to work.

Could you explain what you mean when you say that it needs to be part of the environmental map? That I should use the embossed texture both under the NiTextureEffect entry and under the NiTexturingProperty entry?

Several years ago Bjam has pioneered writing NifScope tutorials for adding NiTextureEffect (reflection) on this (for creatures) and on NifTools (other game objects) forums. NiTextureEffect addition is a crucial step for applying MW bump maps. I have converted these tutorials in pdfs:

Environment map texture file and bump map texture file are two different textures.

Thank you! I am downloading the file now.

You can do that. but all you'll get is a fake bump. More at just added looking depth. Like Connery does. You need to look up environmental maps at nifs forum. Then attach it to that as a bump...Or a normal map as it 's only looking for a value.


Environmental maps is the term the industry uses for reflective maps and so on. The bump or normal needs to be attached to the reflective/environmental map.
