Shaders reflections changes ?

[YouGroove]

I updated my project and the last changes made the PBR style shader only reflect in a side of the models with a strange reflection.

[Josh]

When decals were added I had to switch the material flags and specular values in the gbuffer.

[YouGroove]

I find that LE3 official shader "diffuse+normal+specular+env" just don't produce no environment effect at all.

[macklebee]

Its because the default shader calculates the cubemap colors combined with the specular texture but then never does anything with that variable ('emissions'). Another thing to consider is that the texture slot for the cubemap is texture 5. Also, keep in mind that there is no default env shader for animated models.

I put one on texture 5 slot , but nothing happens.

I was seeking some reflective material effect for static models not animated.

 

LE3 is not able to have buidling windows reflective like this simple shader ?

How can we do ?

[Josh]

The cubemap goes on texture slot 5, and if you change the last line of the pixel shader to this, it will appear:

fragData2 = vec4(emission.rgb,specular);

 

It just doesn't get used in the default demos, so this got missed. Adding the fixed shader now...

[YouGroove]

I changed the last line, still the effect is very strange ad the reflections depends on the camera height or movement it makes on part reflective and another part not reflective.

 

Is there something specific i missed ?

Edit: Josh I think calculation for reflective cubemap is wrong.

 

line 63 and 64 :

 

 //reflectdir.y *= -1.0; //no need
cubecoord = reflect(cubecoord,reflectdir); //reflect cubecoord by reflectdir not the other way around

[YouGroove]

I applied your changes Shadmar, but the reflection is still depending on camera position

Also is the reflection half mixed with diffuse map or can we control in some way how much it reflects ?

[shadmar]

That looks like smoothing problems. What happens if you recalc normals using 35 or 50 degree angle.

[YouGroove]

I recalculated, but they still look bad and moving the camera the reflections still changes reflections.

[YouGroove]

Another problem using a simple texture and normal map it makes artifacts depending on camera distance.

 

I am not a shader coder, i will just wait for some tested working version.

[shadmar]

They are reflections, they are suppose to reflect environment when you move the camera.

Show me a video and your shader.

[YouGroove]

It is a problem with camera coordinates projection, ad we expect reflection on the whole surface.

 

Just do like me and copy and change some developper material to test it.

[YouGroove]

line 63 and 64 :

 

//reflectdir.y *= -1.0; //no need

cubecoord = reflect(cubecoord,reflectdir); //reflect cubecoord by reflectdir not the other way around

 

 

 

It works, thank you for your help Shadmar.

Some usefull modification to tweak models reflection power in the editor :

 

Change this line of code in LE3 Environment shader to be able to control the level of reflection using the specular material adjustable value.

 

vec4 emission = texture(texture5,cubecoord) * texture(texture2,ex_texcoords0) * materialcolorspecular ;
