Hi Ats, But I really don't understand why the noise bitmap is working on PC, but not on Android. It's just white. Could you try adding a BitmapExpression containing "Pixel.A = 1" to your NoiseBitmap? So, like this: ZZDC<?xml version="1.0" encoding="iso-8859-1" ?> <Bitma...

Hi Ats, I was looking at your phong shader, and while it's really showing the use of Specular and Emission colors, it doesn't show up on ES2/GL3. Right, as mentioned .. it's a shader for legacy OpenGL so it doesn't work ( properly ) with ES2/GL3. I'm going to start over again, and searching for exam...

Hi Ats, Let's say, the phong one. That phong shader is written for legacy OpenGL ( GLBase = compatible ). I suspect you changed the "gl_ModelViewProjectionMatrix" part in the fragment shader, but that's not nearly enough to convert it to a modern shader ( GLBase = GL3/ES2 ). Anyway, here's...

Hi Ats, What would be the logic to update the light shader, so the cube doesn't rotate with his shadows stuck on it? What light shader are you referring to? I looked at all the examples you posted in this thread but i can't find a light shader. I've read many explanations, but since GLES2 is aging f...

Hi Ats, And another weird thing is happening: when you press SPACEBAR to display the text, alpha shader cease to work. I'd really like to understand why... :? It's because you're enabling blending once in your App.OnLoaded and then RenderText overrides the OpenGL blend state and doesn't restore it p...

Hi guys, why the alpha transparency shader is working on App.OnRender, but not in Model.Onrender? You mean when previewing SphereModel? Transparency does actually work, but it's not very "pronounced" due to the background color and your alpha value. https://i.imgur.com/MiBPm8A.png I can us...

Hi Ats, Oh. So MeshSphere can't do that, but rounded MeshCube can. You can still use MeshSphere if you want .. you just need to add a MeshExpression where you assign the texture coordinates yourself. Here's a simple example: <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplicat...

Hi Ats, But putting it to ModelDefined doesn't light up the sphere. It's still black in preview, and white in release. No texture. As mentioned, that's because MeshSphere doesn't generate any texture coordinates, so the bottom-left pixel ( texCoord 0,0 ) of your texture ends up being used for the en...

Hi Ats, The first should display the same texture as the ground, but it is black instead. You can't use "Generated" TexCoords ( which uses glTexGen ) in OpenGL ES, you have to use "ModelDefined". However, a MeshSphere doesn't generate texture coordinates for the mesh ( not sure w...

Hej Ville, Kjells suggestion sound ok, and it may not even be needed to save/restore the blend state at all. It depends on where it is used. Saving & restoring the blend state in RenderText.Execute isn't needed no, but since you haven't implemented attribute masking in fakePushAttrib it happens ...

Hi guys, Here's the result on the old Galaxy SII (2011) That looks correct :) I just tested on 2 Android devices myself and had similar results; it worked properly on one of them and i had the same issue as Ats on the other. @Ville - Maybe it would be easiest to ditch the glGet calls in fakePushAttr...

:| Alright, seems like glGet(GL_BLEND) simply returns the opposite of what the current blend state actually is. So it returns FALSE when blending is enabled and TRUE when blending is disabled. This could be a Android OpenGL driver issue rather than a ZGE issue ( not 100% sure though ). I'll try to t...

:| Dang-it, didn't know / forgot(?) that Transparency=BlackColor results in white pixels ( instead of black ) on Android. White-on-white text is a little hard to read you know .. please try the same project with a silver Dina font instead of white: <?xml version="1.0" encoding="iso-88...

Hi Ats, Can you try this project on your Android device? <?xml version="1.0" encoding="iso-8859-1" ?> <ZApplication Name="App" Caption="ZGameEditor application" ClearColor="0 0.502 1 1" FileVersion="2"> <OnLoaded> <ZExternalLibrary ModuleNa...
