I'm having this problem when I put in an object from the object window to the render window. After I put it in there, it shows it as a giant white exclamation mark.(Kind of like the yellow and gray ones in game, but all white.) This object is a door that I made. I took an IC door and changed the texture to my texture that I made. (the texture appears and works correctly in NifSkope) I put it in the CS by making a new door object and choosing the new .nif I had made. I gave it a name and sounds and all that jazz. But it doesn't work when I add it into the render window. It just shows up as a giant white exclamation mark. I've successfully put custom items that I've made in the game before with no problems. So what does this mean? I've never seen this before.

PS: I'm a bit of a beginner to modding and I hope I gave enough detail as to the situation.

Edit: All the textures and .nifs are in the right spots so it should be able to find them.

Have you placed the .nif in your meshes folder? (Same for the texture. (edit= for the textures folder of course.))

Yes, I double-checked and then triple-checked for that.

Hm, maybe CS has a permission issue? Are you using vista/7? Try running CS with admin privileges. It's unlikable but worth a try so you know it's that or not.
Otherwise upload it at some place so others can take a look at it (4shared/rapidshare/megupload). The texture would suffice to get a door, but the nif file with it could provide an answer to your problem .
That way we can blame the os instead of the file :laugh:. To me it looks that it either loss some data in the file or CS is having trouble at it own.

Okay, I figured out that the white exclamation is the ol' yellow and blue one, which means missing mesh. (It was white because I had the brighten lights option flicked on.) So I figured that the path was too complex to my mesh, so I moved it up a few branches and now it can find it, but now it can't find the texture(I think). Its all pink now in the CS. I moved the texture up a few branches within the folders and double-checked that it had the correct naming to match the .nif, but it still shows up pink...

So...you did assign the texture (placed in the textures folder) at the nif? http://cs.elderscrolls.com/constwiki/index.php/How_To_Create_New_Re-Textured_Items Just to be sure , naming is irrelevant.. just useful.

Okay, I got it working. Apparently, in this situation, anywhere but \data\textures is too complex for the CS to find. I moved the mesh and the texture to the simplest place possible. (\data\textures) Now everything is working correctly and I have my door. All my other retexes are within many folders within the textures/meshes folders, and they all work fine.

The texture is assigned by the NIF file, not the CS, and it is relative to the DATA folder, I believe.

So, the path given in the nif has to be "textures\myarmor\myarmor.dds", not just "myarmor.dds" and absolutely not "C:\My Games\Bethesda Softworks\Oblivion\Data\Textures\myarmor\myarmor.dds".
