How can I use render to texture with Ogre? (Solved)

[Hansel]

Hi

I'm triying to use render to texture with Ogre to add a "complete map" to my mesh. I'm doing it with 3dsMax 8.

I follow the next steps:


- First I build a simple scene (a cube over a plane) with a simple texture on it and then I add a ligth.





- Second I go to Rendering-> Render To Texture and I select in Render Settings "3dmax.scanline.radiosity.high", in Mapping Coordinates I turn the obtect channel to "1" and then I add a Complete Map Size = 2048. I push render button.







- After pushing the button this is the result in the viewport:





- And an Automatic Flaten UV is added to the scene.




But then I have the problem, because I don't know how to export it in Ogre. I try to add an UVW map with Vertex Color Channel turning on to let the texture coordinates as they was, I try to aply a new material in the scene using the complete_map.tga, I try to change the channels values and finally I try loading material directly in ogre with mesh->setMaterial, but unfortunatelly anything works


Anyone can help me? Thanks

I see that you are running MAX - why not go to the oFusion Forum and see what it can do for you?

There's even a complete tutorial about how to do what you are trying to do.

But I don't use ofusion, I use Ogre Exporter

[jacmoe]

So?
You can read the tutorial anyway?

Sorry, I thought It was only for using with ofusion Thanks

Even if you're not actively using oFusion, there's a lot of valuable MAX wisdom to gain from the oFusion community.

I've found this tutorial http://ofusion.inocentric.com/tutorial4.html but it doesn't show me how to export lightmaps and shadow maps in order to launch in Ogre, just how to use them to export with ofusion

I think MAX is creating those files for you, am I right?
If that's the case, just grab them and apply them to your mesh through a material script.

I try it before but then the problem is with the UVM map:




I add a simple UVW map with the vertex color channel selected to leave the Automatic Flaten UV as it was but when I launch the mesh using this script:

Code: Select all

- In C++ -> plane->setMaterialName("rendertotexture");


material rendertotexture
{
    technique
    {
        pass
        {
            ambient 0.588235 0.588235 0.588235
            diffuse 0.588235 0.588235 0.588235
            specular 0.9 0.9 0.9 0.0
            emissive 0.0 0.0 0.0
            texture_unit
            {
                texture plane1000x1000.tga
            }
        }
    }
}

I get the result you can see in the screen

I've solved it changing render to texture map channel to "1" again, exporting mesh only with the Automatic Flatten UV and finnally launching it manually with setmaterialname

Thanks for all, jacmoe
