BB01.dds texture question

Post by **Adonis VII** » Thu Aug 06, 2015 4:49 am

The billboard texture textures\architecture\urban\BB01.dds is odd. In viewers or UV mapping in Nifskope its mostly black with patchs of what seems like foam. However when a model is actually rendered in NIfskope or in game, its as expected:

Why is this? I'd like to make a LOD for these billboards, but the end result is just the texture as seem in the UV Mapping window and not the normal render.

Well,

[collapsed title=What it looks like you're seeing in nifskope is the alpha channel applied to the diffuse.][/collapsed]

[collapsed title=Like this:][/collapsed]

Not sure why nifskope would be blending the two textures together in the viewer.

So using the unedited texture (obviously I would reduce its size drastically, but just for testing didn't edit), the LOD mesh generates the billboard and[collapsed title=Renders correctly in Nifskope] [/collapsed] [collapsed title=Doesn't render correctly ingame] [/collapsed]

Why might that be that both the Nifskope UV windows and the in game LOD render both bug out?

Are the triangles on the LOD mesh facing the right way?

Did you look at the alpha channel for the atlas texture (or, idk how you're doing this LOD generation stuff) to see if it has 100% transparency?

Yep, it seems the alpha channel in the atlas texture is is making it transparent. However, I still can't seem fix this with GIMP as removing the alpha channel just gives white in the regions where it was transparent. This isn't an issue with bb05 or bb08.

Go to channels, deselect Red, Green and Blue, then paint over and it should bring the opacity up.

Actually... invert the alpha channel and see how that looks.

Got it working, thanks for the advice: [collapsed title=Billboard LOD] [/collapsed]

Even billboard LOD Adonis? Wow... this is going to be awesome, thank you for all the work that's going into your LOD overhaul.

Well billboards are another low hanging fruit. Texture is only 128x256, and the front face is 2 polys. NV already has some LOD for them, but its only for the metal beam and supports, not the actual artwork. So why not.

EDIT: Make that 128x64.
