ModelRenderable with ChromaKey

[caiocs]

Hello,

I used to use the SceneForm 1.15.0 and works fine with the example chromakeyvideo. They used a video_screen.obj and a material.mat, this generate a .sfb file and with that I could create a Model to show my video with chroma.

The .sfb file doesn't work any more with the SceneForm 1.16.0+. Any one has any sample how put the chromakeyvideo example to works on the the 1.18.0+?

Here is the example how I used to load a ModelRenderable to insert my video with chroma, how can I do the same thing with a glb model and a external material to use the parameters inside this material (chroma)?
ModelRenderable .builder() .setSource(this, Uri.parse("video_screen.sfb")) .build() .thenAccept(modelRenderable -> { modelRenderable.getMaterial().setExternalTexture("videoTexture", texture); modelRenderable.getMaterial().setFloat4("keyColor", new Color(0.1843f, 1f, 0.098f)); modelRenderable.getMaterial().setBoolean("disableChromaKey", !isChroma); renderable = modelRenderable; });

If you can wait a little, since there are some others requests on it. I'll soon put a sample.
If not, you can make it like this :

• Convert the plane model obj to glb or create new one using blender or build it programmatically with ‘VertexBuffer‘
• Generate the .filamat from the .mat file using Filament Tool
• Load glb model and apply the external texture from your MediaPlayer
• Share your code and files here ;-)

HI @ThomasGorisse,

How can I set the parameters from my material if I'm changing the whole material like a external texture... today my external texture it's where I put my media player.
ModelRenderable .builder() .setSource(this, Uri.parse("video_screen.sfb")) .build() .thenAccept(modelRenderable -> { modelRenderable.getMaterial().setExternalTexture("videoTexture", texture); modelRenderable.getMaterial().setFloat4("keyColor", new Color(0.1843f, 1f, 0.098f)); modelRenderable.getMaterial().setBoolean("disableChromaKey", !isChroma); renderable = modelRenderable; });
The file video_screen.sfb it's the object that I use to play the video, the material that I have has the parameters: videoTexture (Used to play the video), keyColor (The color of the chroma) and disableChromaKey (Used to disable chroma when it's not needed).

I tried to convert the video_screen.obj to video_screen.glb, but how can I load a material file inside the ModelRenderable to be able to set the parameters videoTexture, keyColor and disableChromaKey?

The 1.18.8 release solves some Material issues and brings a Video Texture sample
Release 1.18.8 - Video Texture + SceneView Background

I'm getting this error when trying to get the version 1.18.8:

Thanks for the report.
It looks like an error in the last commit. I'll fix it quick.

[ThomasGorisse]

@caiocs I pushed an update.
Can you try again removing after cleaning the gradle cache ?

[caiocs]

Got a new error:

'Could not resolve all artifacts for configuration ':app:debugRuntimeClasspath'.

Could not find com.github.ThomasGorisse.sceneform-android-sdk:sceneform:-SNAPSHOT.
Searched in the following locations:

I already disabled the offline mode from Gradle.

I downloaded the code on git hub and imported to my project and everything works fine. The problem it's to try import direct from git hub or JCenter.

[ThomasGorisse]

The problem comes from jitpack old cached versions.
Now that the 1.18.8 is out, you can just use the jCenter artifact by removing the maven { url 'https://jitpack.io' } lines
And using this dependency :

dependencies {
     implementation("com.gorisse.thomas.sceneform:sceneform:1.18.8")
}

Hi @ThomasGorisse ,

I did that and doesn't work. I was at the bintray page and find the the url 'https://dl.bintray.com/thomasgorisse/maven/' on the top right of your page, putted this in my build.gradle and works.

maven { url 'https://dl.bintray.com/thomasgorisse/maven' }

if I put only jcenter the app cannot found the project.

[ThomasGorisse]

Fixed with mavenCentral() : 2494f6e
