*noob* multitexturing a complex building

Hello everyone ,

I am new to ofusion and just started with it. But not getting texturing that fine (specially multi object ,multitexturing). Any tuts for newbies about texturing .

PLease Help

Texturing and material tutorials will be posted later

What effect you need/want to do?

sir,

I have designed a building in 3dsmax having multiple rooms . Now I wants to mutitexture the building . So that I can see that with textute in Ofusion.

How to do that.

If you have worked with the tutorials, then you should understand the material system

Read the "Working with Materials" chapter of the User's Guide to earn what are the techniques, the passes and the textureUnits

Multitexture is different from Multi Material, so if you need to have different materials or textures for different parts of your object, you should use multi material with the Multi/Sub-Object material, then you can upgarde this multi material to ogre material and use the advanced options

Multitexture is for creating effects with multiple textures on the same geometry, blending or mixing textures over (i.e. lightmaps, grass/mud terrain), or environment maps

Multitexture is done by adding textureUnits in the pass material

Test by playing with the "Blend mode" setting of the TextureUnit (with several texture units in the same pass) and see how they work

If you have worked with the tutorials, then you should understand the material system


Where are these tutorials?
Do you mean these? :
http://www.ogre3d.org/wiki/index.php/DCC_Tutorials

I'm pretty new to orge/ofusion too and got alot of issues to get my models properly exported, but these tutorials doens't explain how to set up materials and how to export it.
I'm interested in "Working with Materials" and i would like to understand the workflow.
The ProManual at ofusion seems be locked for pro-users only? - as i can't open the chm.

I guess he meant the ofusion tutorials

"Evaluating to Ogre Materials" or "update to ogre material"
that's what i like to do, but i tried to open the ogre viewport in 3dsmax7 and it doesn't work.
Does the viewport only work in the pro version of the plugin?

If you´re evaluating a textured building and you´ve problems:

you probably did not set the "self ilumination" to white.

There is a script wich is supossed to work that sets all your submaterials "sel f ilumination" to white. As far as I´ve tested in serveral times, it does not work.

Is there a message when you activate the viewport or other hints that might help in defining what your issue is?

I tried a few ogre exporters lately, probably it messed up the ofusions plugin. I reinstalled ofusion and the viewport is working now.
But i haven't had a chance to test it yet, at least i can follow the tutorials now.
Thanks for the tipps

Maybe i had it to black, i think its default in material editor.
But you can copy/drag materials slots in 3dsmax easily, so you just have to set up 1 slot and drag it to the other, you just need to change the texture.

good luck and dont forget to show us your results

Multi sub object is working now, but i used a transparent texture. Now the engine doesn't render the textures behind transparent surfaces... it just renders the terrain behind transparent glas.
Can someone point me in the right direction?
It's shown in the ogre viewport, but not in game.

Review your material (pass) z buffer settings (depth write, read)

Here is an ingame screenshot. Below is the material file of the greenhouse (#3):

I also got a problem with normalmaps, if you still disposed to help with that, too.
The box with the normalmap (#2) is working in 3dsmax ogre viewport but it's shown different in game.
Here's the code for the box:
material aaa_test
{
technique
{
pass
{
ambient 0.588235 0.588235 0.588235 1
diffuse 0.588235 0.588235 0.588235 1

}

}

}

Would be great if you could take a look at the materials and point me to the issue(s).
ta

To enable alpha blending, you set the blend to "alpha" (Src Alpha, Inv Src Alpha)

Then you can control the transparency with the "Opacity" value

Disable z write (Depth write) to display the objects behind the transparent material

Why you have a different cull software and depth funcs?
