Hi,
I prefer to open another post rather than using that of another guy.
I was just looking to do a simple transparency effect with the specular.
I tried all shaders none can do it, a little help please.
Nicolas

Yes, I know that's what I do.
I already doing this, the problem is that with the framework, I can't operate properly. I'll try to post tonight from home.

I also have the same problem, I can not get transparency with specular.
Also how to run the refraction shader with the framework ?
And again, why there is a *0.5 in the shininess mesh.frag reducing by half the intensity of the specular
shininess=clamp(shininess,0,1)*0.5;
Let us choose the intensity of specular through a variable

Hi,
Is it possible to retreive or set the properties of an material on runtime without read or write on the .mat file ?
I would like to retreive or set :
* Depthmask
* colormask
* alphatest
* etc ...
Similarly we can load or create a material, but if we want to save it we must write The function to do it?
thank
Nicolaas

Thank a lot macklebee, every thing is working now !
I can explain why I have some bug in my test, I set a setting like this SetFarDOFRange(200,500) (too large to be seen with my scene), I created a new camera and I saw my DOF.
Necessarily when I have my skybox, I used the camera of the framework (which is normal), but the range of DOF was too large to be seen.
Now we know that with a camera set up in parallel to those of the framework we see the DOF even if it is out of range.

I don't say it doesn't work, I say I can't make a skybox and DOF work with the Framework.
It's either one or the other, look at my screen capture.
Ditto for the HDR, if there is a skybox that doesn't work anymore, if I remove the skybox there is a visible difference between HDR and not HDR ... look at my screen capture
May be, there is a little bug with the framework, or can you post a complete exemple of DOF + SKYBOX in blitzmax made with the framework
Nicolas

Thank but The textures aren'tmine, but come from Filax of Blitz3Dfr
I am testing in the editor, and it's even more strange, I have the DOF and the skybox, but no HDR ...

Hi,
Yes, me again
, I'm looking at every feature of my new 3D engine But Like my other post, may be a bug or not :
HDR => OK
DOF => OK Only if I create a new camera, I don't use the camera who come from the framework
HDR + DOF => OK Only if I create a new camera, I don't use the camera who come from the framework
skybox only => OK Only if I use the camera who come from FrameWork
HDR + skybox => not ok, I don't see the HDR
HDR + DOF + skybox => not ok, because I must use a new camera to see the DOF and with a new camera I don't see the skybox
If someone have a complete exemple it will be good
My scene with out HDR
HDR set to TRUE
HDR set to TRUE + Skybox => :-( non HDR
DOF set to TRUE + Skybox with a new camera => I dont't see my sky
DOF set to TRUE + Skybox with framework camera=> I dont't the DOF

Thank a lot, it's working fine now

Hi
I can't seem to render the sky with the framework, I do not know what I wrong. After I tried to do it with the editor, and when I load my scene, the sky does not appear either but I see it on the editor
My code source :
SuperStrict Framework leadwerks.engine Import "Framework\framework.bmx" AppTitle:String = "skybox" RegisterAbstractPath(CurrentDir()) 'Create a Graphics window Graphics(1024, 768) RegisterAbstractPath(CurrentDir()) 'Create a new Framework object. Global fw:TFramework = TFramework.Create() If Not fw RuntimeError "Failed to initialize engine." Global Camera:TCamera = fw.main.camera SetSkybox(LoadMaterial("abstract::FullskiesBlueClear0016_2_L.mat")) Global Light:tLight=CreateDirectionalLight() Local camrotation:TVec3 = Vec3(0) Local mx:Float Local my:Float Local move:Float Local strafe:Float Repeat mx=Curve(MouseX()-GraphicsWidth()/2,mx,6) my=Curve(MouseY()-GraphicsHeight()/2,my,6) MoveMouse GraphicsWidth() / 2, GraphicsHeight() / 2 'Add the mouse movement to the camera rotation camrotation.x=camrotation.x+my/10 camrotation.y=camrotation.y-mx/10 move=Curve((KeyDown(KEY_Z) Or KeyDown(KEY_UP)) - (KeyDown(KEY_S) Or KeyDown(KEY_DOWN)),move,20) strafe=Curve((KeyDown(KEY_D) Or KeyDown(KEY_RIGHT)) - (KeyDown(KEY_Q) Or KeyDown(KEY_LEFT)),strafe,20) MoveEntity Camera,Vec3(strafe/5,0,move/5) RotateEntity Camera,camrotation If KeyHit(KEY_ESCAPE) Exit If AppTerminate() Exit UpdateAppTime() UpdateWorld(AppSpeed()) fw.Update() fw.Render() Flip(0) Forever fw.renderer.gbuffer = Null End -
I just try the raod.mat, but if I add mesh_shadow.vert on Shadow Vertex it's Ok, may be it's the map ...

Me again :-(
I have an Acces Violation with the new Material Editor when I click on Compile ...

ok thank, I will put the clamp.
It seems that there is more subtlety of this type, are there documents on aspet rendering of engine ?
Nicolas
-
After the update, I still don't understand why there's a clamp on:
shininess = clamp (shininess, 0.1) * 0.5;
It reduces the effect of brightness that doesn't make very good glossy effect.
A screenshot with the original mesh.frag
I removed the clamp
How can I do to accentuate the glossy effect ?
-
I going to tried it tonight, thank you
I had an idea to use flat normal map to a plastic effect (with specular), but I thought it was binding, and especially the shader Mesh_diffuse_specular exit in all shader.pak .
Maybe he should do the housework in sharder.pak.
I suspected that this was not normal that I should edit this file, but neither the effect of parallax, the specular or bumpmap not working before my change
thank you for the reactivated

Hi,
I am very angry, I just made the acquisition of leadwerk and for now I spend my time to debug mesh.frag file. LW based on shaders, but the basic shaders are not operational see missing. Before I negotiated resolution to look at the mesh.frag file I tried with another machine doesn't have a graphics card of the same constructor.I 'm not a pro-shader programmer, it's hard to understand and I don't think my changes is the best
My modifications :
* Change the parameters to operate the parallax (Les valeurs de constante étaient trop petites)
* Removed a clamp to have a specular with bumpmap (
* Write the total management of specular without bumpmap (LW_SPECUALR never dealt with outside of the tag LW_BUMPMAP)
* What else ?
It is not possible ! in the 2.32 package isn't the final sharder.PAK?
. I believed in what he described on the cover page:
Materials are the key to next-generation graphics. Choose from our library of effects include normal mapping, specular reflection, cube mapping, parallax occlusion mapping, and more.With Leadwerks, you no longer Have to choose Between Power and ease of use
hum hum....
Hoping sincerely that it is an error during the release of package 2.3 / 2.31 and 2.32. And a version of mesh.frag managing all the fabulous and the basic shader will soon be available. Maybe that olders users have kept a correct version of shader.pak, but for the new entrant is rather discouraging

It's working fine, but as for the parallax effect I modified the file mesh.frag and put in comment the line who clamp the shininess effect
shininess=clamp(shininess,0,1)*0.5;
Since everything is working properly, and the parameters of specular reflection and gloss
I tried on two different PC with one ATI and NVIDIA before to decide to do changes.
Is it normal that I have changed the file mesh.frag on two occasions to have a normal behavior?
I have only version 2.32

Hi,
After parallax & normal mapping, I'm trying to get an glossy effect as plastic.
What is the shader I must use ?
thank
Nicolas
-
It's working find now, I changed the default values LW_POMMAP.
I better understand the general functioning of the management of shaders in LW, There isn't one effect but several normal map effect, after it depends if I want the default specular or via specular texture ...
thank
Nicolas
-
If I understood everything, the parallax effect uses the alpha channel of the diffuse image to cause deep. And you changed the shader core for use in a 3rd replacement textures alpha channel
In a same thing, the normalmapping doesn't work to, I tried some object in the editor like tree, road ... I haven't any normalmapping effect. If I use the tree texture or road texture with Unity or TV3D I have a godd normal mapping effect !
Help, everything works fine with the 2.3 except the effects of bump, normal and parallax

Hi,
I'm new with leadwerk, I come from the Blitz3D & Truevision3D.
I have a little problem, I can not get a correct normal mapping or parallax effect .. also with the materialseditor or edidtor or by programming.
My video card drivers are up to date ...
Unable to reproduce the parallax effect that can be seen on http://www.leadwerks.com/files/Tutorials/CPP/Materials_And_Shaders.pdf, or the results I had with other texture in TV3D.
Specular refection and gloss parameters have no effect on any texture ...
Screenshot from pdf

thank a lot

Hi !
I watch the evolution of leadwerk engine from the first version, and I wonder if the version 2.3 documentation is up to the performance characteristics?
Because looking at the wiki, I can not find the new features related to the 2.3
Sorry for my english

thank, I'll try it tonight.
If I use the framework I must do :
