Material Bloom ?

[ParaToxic]

Hello ,I have a question about a picture and its shader.I played a game and saw (in other games too,but here it looks very nice) that the edges of a model which are directed to the sun have a kind of bloom.

Pic:

 

The problem is,that leadwerks bloom can't work only for a few models in a scene,for example weapons and in the picture the material isn't very fair,so it wouldn't work ,because you need fair materials to bet a shine effect.

 

 

I mean something like that(scroll down for pics) : http://www.ogre3d.or...wiki/Faking+HDR

 

Have somebody made a shader with specular bloom??

When not can somebody tell me how to make that(only the idea)

 

Thanks

Leadwerks already put lighting result in the bloom buffer, and use them in the bloom shader.

But tbh the bloom shader itself is not good.

That Ogre example looks really effective!

LordHippo: Where do you see the lightreult in the bloombuffer?

 

The point is to make a specularbloom shader only for the given material ,because it wouldn't look very nice when all the other objects ,like terrain glows

 

 

First try :

Looks good. I might give a try at porting the OGRE example.

[ParaToxic]

Good luck ,I try it too ,because the example is very nice

One question.As this effect has (I think 8) passes I have to save the stages in buffers/textures.But how to do that?

 

Maybe:

SetBuffer(RTBloom);

SetShader(Pass1);
BindTexture(GetColorBuffer(gbuffer),0);
//Now I want to get the output of the shader,because the shader have a 2D sampler for input and now I need the output written in the //RTBloom buffer
DrawTexture(GetColorBuffer(gbuffer)....); //???? maybe so?
SetShader(NULL);

 

 

So I made it as explained at the top.

But in the last shader I have to put the normnal rendered colorbuffer and the other 4 buffers(blured).So I bind the buffers with BindTexture to the shader ,but now I have to call DrawImage() ,but I have 5 buffers......how to do that?????

Now I made a shader which make specular areas glowing with bloom.Iam going to write a new bloom shader an upload the specular bloom and the new bloom shader.

In the pictures the specular is everywhere,so I don't use a specularmap,as you see,because the hands have specular.

That looks pretty good! And you're right, that definitely gets rid of the cheesy look bloom usually has.
