[TEC] 3d modeller questions

[HELLISH1]

Since I have been getting alot of questions, as far as exporting/importing, mesh editing, and so forth, I decided to make this thread, to help answer questions. So let them rip!

I want to ask about UV-1 and UV-2 maps. but that's really it.

also, I'll be glad to help with answering questions! :up:

when a model is exported from a 3d program like 3ds, it creates a .obj and an mtl file which is a library.


the uv map is the map from which the program gets the coordinates of the various texture parts :


- uv1 is used in our game for the YourSub_T01.dds map = texture Map

- uv2 is used in our game for the YourSub_O01.dds map = Ambient Occlusion Map (computed shadows map since the game doesn't do real time shadows) it contains the texture in black and white in the Alpha channel of the image.

a model with only one uv map shows all black ingame



Normal map : YourSub_N01.dds is a map made out of the texture _T01 : it inverts the blue/green layers thus showing "bumps" in the texture, it is also called a bump map. only works for the hull ingame, not the tower ?

Not entirely true.
There is a setting in S3D that corrects the all black problem.
Remember that early imports from SH3 did not show up black but did have the texture.
I exchanged PM's with skwasjer tonite about this.
It's something none of us ever noticed!
:o

When viewing the UV map preview in S3D, there is a box above the UV Map preview
next to Texture sets/channels:
Change that to a 6 and the black problem goes away!
