Transparent PNG texture problem

Troubleshooting graphics
1

I’m brand new to jMonkey, so it is a little frustrating finding lots of documentation about problems I’m running into but then finding out these answers don’t apply to jme3 or aren’t implemented yet.



I’m trying to create a simple texture out of a PNG that has transparency, but the final texture is all messed up where it should be transparent. Any ideas what I’m doing wrong?

[java]

Material mat1 = new Material(assetManager, “Common/MatDefs/Misc/SimpleTextured.j3md”);

mat1.setTexture(“m_ColorMap”, assetManager.loadTexture(“Models/warriorgirl300pxtall.png”));

geom1.setQueueBucket(Bucket.Transparent);

geom1.setMaterial(mat1);



geom1.setLocalTranslation(0, 0.5f, 0);

geom1.setLocalScale(0.5f);

rootNode.attachChild(geom1);

[/java]



Any help would be much appreciated.

Try this:



[java]

Material mat1 = new Material(assetManager, “Common/MatDefs/Misc/SimpleTextured.j3md”);

mat1.setTexture(“m_ColorMap”, assetManager.loadTexture(“Models/warriorgirl300pxtall.png”));

mat1.getAdditionalRenderState().setBlendMode(BlendMode.Alpha);

geom1.setQueueBucket(Bucket.Transparent);

geom1.setMaterial(mat1);



geom1.setLocalTranslation(0, 0.5f, 0);

geom1.setLocalScale(0.5f);

rootNode.attachChild(geom1);

[/java]



I think all you’re missing is the Blendmode set to Alpha.



Cheers!

That did the trick, thanks so much!



Out of curiosity, is this stuff documented somewhere and I’m just not seeing it? All the stuff on transparent textures I could find seemed to be outdated for jme3.
