Newbie question regarding first basical age

[Lontahv]

Feel free to post some pictures. FCAL's are sort of defunked.

Okay, I´ll upload the screenshots I´ve gathered here, showing my progression:

This was one of my first visits to my age. As you can see, I had only added materials with simple colors to begin with. This was when I had problems with the light.

Woohoo, lighting! The hints you gave me worked great

First basic textures added. I was really happy it worked without big problems... (or at least I thought )

Improved textures - I was instantly happy with the wall textures (and I still am.) What I didn´t notice, was that one of the walls had a texture, which was 90 degrees turned (for what reason, I still dont understand.) I solved it, thanks for the hint!

This was the second copy of the column I had added unintentionally. You can see the flickering, distorted textures on it (I found out quit quickly, what caused the problem and deleted the second column.)

This is the first picture of my handmade "lamp", just a simple UV-sphere with white, bright material.
Now the lighting comes from an actual lightsource, instead out of nothing.
I know, it´s nothing special

Changed the floor texture. The blueish tone was to... well, blueish
You can see the one texture on the column (the right part of the column), which still isnt right... again, the problem eludes me, I dont understand, why it is looking wrong.

on all the walls the pattern is repeated 3 times horizontally.
That single "pillar" wall is textured vertically.
Select the wrong textured pilar faces in a 3 d view window.
unwrap them.
go to uv window
select a to select all the faces in there .
press r to rotate
rotate 90 degrees
that will do it.

( i am afraid you did not uv texture the wall at all, after a second look i think it is orco textured, when i am right then you have to change in the map input tab the input from orco to uv and unwrap the complete walls , because the partly visible wall on the right is also textured in the wrong direction.I)

I´ve added a doorway and a corridor adjacent to my room.

on all the walls the pattern is repeated 3 times horizontally.
That single "pillar" wall is textured vertically.
Select the wrong textured pilar faces in a 3 d view window.
unwrap them.
go to uv window
select a to select all the faces in there .

I just checked the age in Blender and linked in.
It´s okay for me, that the texture is repeated horizontally, so that´s a feature, not a bug


I tried to rotate the pillars face, as you suggested, and this is, what it looks now: (I also moved it away from the walls, so I can get around it and see all the pillars textures)

I double checked all walls - everyone of them is UV-mapped and the map input is set to UV everywhere.

And youre right too about the partly visible wall on the right, it IS textured in the wrong direction...


Now, how can this be? What did I do wrong to cause the textures to be set in the wrong direction? (90 or 180 degrees rotated?)
Is there any setting I can prevent this to happen with?


Ive also big problems with the textures in my corridor - they are completely over-stretched. The walls all are UV-mapped.

The strange thing: you can see the only texture, that is okay, on the second image... EVERY single wall has exactly the same settings!

Am I just plain dumb? What mistake did i make?

Every wall has the same settings , but the walls are different in size.
so you have to size all the uv's in the uv window in relation to the size of the walls
the walls which are streched to much have to be streched in the uv window in x direction, then the pattern will be repeated more in the x direction.
Texture's on the pilars are compressed to much ( repeated to often in x direction), so you have to resize (make smaller) in uv window.
select the concerning faces, unwrap, and scale in uv window.

Am I just plain dumb?

no , you are not, then you would not ask.
Its a matter of experience the whole UV mapping is confusing in the beginning.
If your scene is small , set your 3d view window in texture mode while uv mapping, then you will see what happens when you rescale in the UV window
May be you want to use this testmap first, when the test map is correct on the walls, replace the testmap for the real texture without changing the uv map.

Thank you for this insight on texturing - I´ve struggled with it a lot, and progress is slow.

I´ve revisited my age today, and found out that the axis of the coordinates (x, y, z) in my corridor where a total mess. Blender shows the global axis, local axis etc. - and they NEVER fit with what I tried to set up in the material-buttons. ( you know, the part, where you can specifiy, how often a texture repeats in the x, y and z direction).

So I deleted the whole mess that was a corridor, and started a simpler, smaller one - this time by doing the same thing as with my first room, making a cube, flipping normals, seperating the walls from each other, adding UV-maps, materials und textures - and - heureka! it works!

Teached me not to use one cube per wall - if I rotate the cubes, this seems to ruin the axis.

This is the latest picture of my little age. The new corridor is now perfect, like magic
The pillar still isn´t totally right, but I´ll leave it alone for now and work on it later on.



One thing puzzles me though: Blender should show me my textures in textured mode, right?
But when I switch into that mode, all textures are simply white.
And in the UV-windows, I see no texture, just the vertices and faces I´ve selected.

Ok, so in UV-window there is a drop down for selecting texture. It's visible here (texture "Marble-2001-2002" is selected).
Since You don't see texture, in UV Window instead of selected texture name You will se ony grey button which will open dropdown for selecting texture.

Once You selected texture, You should see it in UV Window and in 3D view. But You should know that its more of a preview. Using described technice You will be able to preview any texture on mesh but only actuall material will apply.
There is also another thing: You can preview only one texture a time (so if I got material with couple of layers with diffrent textures in the 3D view only one a time can be show), but in URU all layers of material will be show.

[dendwaler]

In the Uv window you also have to open the according texture.
you can do that with the arrow up symbol if you already loaded the image when assigning a material.

and they NEVER fit with what I tried to set up in the material-buttons. ( you know, the part, where you can specifiy, how often a texture repeats in the x, y and z direction).

This text gives me the impression you did not use UV texturing at all. You probably only checked the UV button to let it be accepted in Plasma, but in fact are still using Orco as long as you did not overwrite them by unwrapping all the faces! (only Orco has a z direction, UV is 2 dimentional)
Settings must be as in example below.After that go to 3d view window, set window in textured mode, tab to edit mode , press a to select all. press "U" key and choose an unwrap method.
The input scaling is only used when you want a second layer, using the same UV map, but with another pattern repeating in relation to the used scaling in the UV map from the first layer.
This is more advanced and requires some experience.

Try first to do some basic examples i wrote in this thread:
http://forum.guildofwriters.com/viewtopic.php?f=7&t=4032&start=0

edit: I added some text a few hours later.

[Rabenschwinge]

Aaah, I didn´t know you have to select the textures in the UV-window again... I thought they had to show up when the material and texture(s) are set!

I looked into my file again, and I seem to have done things right with UV-mapping, there ARE UV-maps for each of my objects, and there are materials and textures applied.


Do I understand you correctly, that the "sizeX", "sizeY", "sizeZ" - settings I should only use, if I use more than one texture?

*me bangs head against table*

Well, that explains a lot of my problems

I will look into the thread you linked to, and try to understand the examples there, thank you!
