change the texture!

[Gilmer]

I have a model, which will begin to load with this material:

 

texture0="cardif.dds"
texture1="cardot.dds"
texture6="reflect.dds"

cullface=0

shader="abstract::mesh_cube_reflection_bump_difuse_specular.vert","abstract::mesh_cube_reflection_bump_difuse_specular.frag"
shadowshader="abstract::mesh_shadow.vert",""

 

 

But I want the script in this model, in the update it, pass the image of the a texture, which was taken from the buffer(GetColorBuffer()) to the "texture6=...", because this textures will always changing, like a reflect, so i would like to change in the shader too, and show this change. The my question is, what are the commands necessary for this? I tried a lot of commands to set materials, shaders, textures....but so far i not getting results..

 

Edit: i need use, some like the BindTexture()??

[Gilmer]

Josh,

 

You would have some example to change the layer of the texture of shader that already this in execution?

 

 

Regards

[Gilmer]

Somebody could help me?

 

I am needing really to know as it modifies the texture of a layer of shader, but in execution

 

I have date to finish the project

 

Thanks all

Hi Gilmer.

The code should look something like this:

 

Entity myEntity("abstract::myEntity.gmf");
Mesh myMesh=myMesh.FindChild("myMesh");
Material myMat=myEntity.GetSurface(1).GetMaterial();

Texture tex;
tex=buffer.GetColor();
myMat.SetTexture(tex);

 

This is how I did it. Hope it will help.

Hello Arbuz, thanks for feedback, i did something, and really worked. But not yet completed, i noticed the followin: when i create a texture to skybox and cubemap, by the photoshop using the NVidia dds, i need set to "cubemap" instead of "2D Texture". But if a create in the leadwerks, get the buffers to use as texture, it does not work, because it dont is set for "cubemap". Have someway to i create this texture in memory, being that i want use to cubemap, and not to comum texture?! Im using a shader to fit the texture in the model, as cubemap. This is the code witch im using in the script:

 

require("scripts/framewerk")
require("scripts/class")
require("Scripts/constants/engine_const")
require("Scripts/LinkedList")
require("Scripts/filesystem")
require("Scripts/math/math")

local class=CreateClass(...)

fw=GetGlobalObject("framewerk")

--CONST
drawscreen=0 --desenhar na tela?

function class:CreateObject(model)
local object=self.super:CreateObject(model)

chave=0


cameracube = CreateCamera()
CameraClearMode(cameracube,1+2)
cameracube:SetPosition(model:GetPosition())
cameracube:Hide()
rotcam = cameracube:GetRotation()

maincamera = fw.main.camera

-- buffers
mainbuffer = CurrentBuffer()
buffercam = CreateBuffer(GraphicsWidth(),GraphicsHeight(),1+2+4)
buffertex = CreateBuffer(256*6,256,1+2+4)
bufferprint = CreateBuffer(256*6,256,BUFFER_COLOR)

colorbuffer2=CreateTexture(256*6,256,2+4)
TextureFilter(colorbuffer2,1)


entity=FindChild(model,"cube")
surf=GetSurface(entity,1)
mat=GetSurfaceMaterial(surf)
shader=GetMaterialShader(mat)

texreflect=LoadTexture("abstract::reflect.dds")
texreflect2=LoadTexture("abstract::reflect2.dds")
texxadrez=LoadTexture("abstract::reflect_xadrez.dds")
texxadrez2=LoadTexture("abstract::reflect_xadrez.dds")

and this is the shader:

The functionality to combine 6 textures into a cubemap at runtime might be here:

http://www.leadwerks.com/wiki/index.php?title=Buffers#SetColorBuffer

haven't tried it yet though.

[Gilmer]

Thanks Masterxilo, but where should I put it in code? And for example, as each side of the texture is 256x256, so the texture would have a whole 256*6x256, right? The texture is that i create have to have this size or should i put it as 256x256, so that it will add a side by side?

[Gilmer]

anyone??
