I thought that it was a color thing that nothing I do makes an object fade in or out with the software render. This is a basic test I wrote (several different attempts in there, none of which work):

import java.awt.*;
import java.awt.event.*;
import com.threed.jpct.*;

public class Transparency extends Frame implements WindowListener {
    private World theWorld;
    private FrameBuffer buffer;
    private Camera cam;

    private boolean keepGoing, turnRight, turnLeft;
    private com.threed.jpct.util.KeyMapper keyMapper;
    private Texture boxMap;
    private int transparency = 0;
    private FadeoutEffect effect;

    public Transparency() {
       this.setTitle("BR's");
       theWorld = new World();
       buffer = new FrameBuffer(1440, 900, FrameBuffer.SAMPLINGMODE_NORMAL);
       obj = com.threed.jpct.util.ExtendedPrimitives.createBox(new SimpleVector(2f, 2f, 2f));//Primitives.getCube(1f);
       TextureManager.getInstance().addTexture("boxMap", (boxMap=new Texture("BoxMap.png", true)));
       boxMap.setEffect((effect=new FadeoutEffect()));
       obj.setTexture("boxMap");
       obj.build();
       obj.setTransparencyMode(Object3D.TRANSPARENCY_MODE_DEFAULT);
       obj.setTransparency(transparency);
       Object3D backgroundPlane = Primitives.getPlane(1, 4f);
       backgroundPlane.build();
       backgroundPlane.translate(0f, -2f, 0f);
       theWorld.addObject(backgroundPlane);
       cam = theWorld.getCamera();
       cam.moveCamera(Camera.CAMERA_MOVEOUT, 8f);
       theWorld.addObject(obj);
       obj.setLighting( Object3D.LIGHTING_NO_LIGHTS );
       keyMapper = new com.threed.jpct.util.KeyMapper(this);

              keyReleased(keyState.getKeyCode());
           if (turnRight)
              obj.rotateY(-.01f);
           if (turnLeft)
              obj.rotateY(.01f);
           theWorld.renderScene(buffer);
           theWorld.draw(buffer);
           //theWorld.drawWireframe(buffer, Color.yellow);
           buffer.display(this.getGraphics());
           Thread.yield();
       }
       buffer.dispose();
       this.dispose();
       System.exit(0);
    }

    private void keyPressed(int keyCode) {
       if (keyCode == KeyEvent.VK_RIGHT)

           if (transparency < 255)
              fade = (float)((transparency+=8)/255f);
           effect.transparency = 255-transparency;
           obj.setTransparency(255-transparency);
           //boxMap.setAlpha(255-transparency);
           TextureManager.getInstance().replaceTexture("boxMap", boxMap);
           //obj.setAdditionalColor(intensity(boxColor, fade));
           //boxMap.applyEffect();
           Logger.log("Transparency: "+transparency, Logger.MESSAGE);
       }

No, it's working on full 24 bit color depth.

If I'm not mistaken, the software renderer works with 16 bits for color (and a third byte for transparency?). Is it trivial giving it all 24 bits (plus a byte for transparency). If so, would you?

It should work now.

I found the issue, but I can't fix it myself. I have to contact my provider.

I see. That's a bit strange...the forum has a database user configured which works for everything else for some strange reason not for the search. I'm not sure why that it, I'll have a look and try to find something.

Please try to search for a topic. It doesn't fail sometimes, it fails every time.

It's nothing that I'm doing at least. I can only imagine that it's the JIT-compiler kicking in. Older VMs had the option to compile everything at startup. I'm not sure if this option is still available on newer ones but if it is, it might be worth to try to see if it fixes the problem. It might not be a good option in the end, because it hugely increases startup time, but to track down the problem, it might help.

Never seen it and I got no error mail either. I had to upgrade the forum because of the old version being insecure and unspported. As long as it only happens every not and then, I guess we have to live with it.

I've tested it with Edge, just in case. Same: "Database error. Please try again. If you come back to this error screen, report the error to an administrator."
