TGEA 1.8.1 ISSUE - Grey boxes around bitmaps

#1 Pictures would be great regardless. Pictures of the issue and the bitmap outside of Torque would be even more awesome :).

#2 I've got both as PNGs so you can have a pixel-for-pixel diference. Hope this helps! If you need anything else, please let me know.

Here is the screen shot:


And here is the original graphic:

#3 Hmmmm... There are transparent parts to the original graphic. You might be better off downloading these...

#4 I'm having trouble reproducing this. Here's what I'm doing:

1) I have downloaded the texture and placed it in GameExamples/Stronghold/scriptsAndAssets/client/ui
2) I have changed the bitmap used for the MainMenuGui (set in mainMenuGui.gui) to "hudfill"
3) I have added the following block as a child of MainMenuGui

new GuiBitmapCtrl() {
      bitmap = "./TGEA181GreyOrig";
      visible = "1";
      position = "250 250";
      extent = "450 180";
   };

Having done this, I'm not seeing the issue. Could you post the GUI definition you're using when you see this issue and, if you have time, try the steps above yourself?

#5 Hi Alex.

I put screenshots and explanation on the same issue here : www.garagegames.com/community/blogs/view/16325/2#comment-110583

The grey lines doesn't appear the first time you launch the app. You have to go to the 3D environment once (where all is visually OK) and then back to your menu, where grey lines starts to appear.

#6 Unfortunately that isn't triggering the issue for me either. I'll try the actual 1.8.1 download instead of my svn checkout. There shouldn't be any difference, but...

#7 Seems like texture wrapping is turned on and your texture top row (which is opaque) is wrapping into the bottom (transparent) by half a texel.

This looks like a classical render state leak... but shouldn't GFX2 eliminate those?

#8 This is probably useless but I remember a similar issue in *TGE* running OGL on windows.

#9 @Manoel: You are indeed correct, wrapping is enabled. And it's not a leak. GFXDrawUtil defaults to wrapping. I still can't repro the issue, but you could try changing

GFX->getDrawUtil()->drawBitmapStretch(mTextureObject, rect, GFXBitmapFlip_None, GFXTextureFilterLinear);

in guiBitmapCtrl.cpp (~line 161) to

GFX->getDrawUtil()->drawBitmapStretch(mTextureObject, rect, GFXBitmapFlip_None, GFXTextureFilterLinear, false);

#10 Hey guys, I hate to bump a thread, but I'm going to be doing a pass on TGEA bugs soon and since I can't repro the issue myself it would be extremely useful to know if the fix I gave above works.

#11 I'll test this tonight and let you know. Later!

#12 TADA! Sure enough, Alex, it did work. I put it into the GuiBitmapCtrl and it fixed my problem. I'm still seeing it in a custom GUI class of mine, but at least I know I can look at the GuiBitmapCtrl to see what I might be doing differently from it.

Thanks!

#13 Sorry Alex, but it doesn't work for me.

As soon as I go in 3D mode (past my 2D welcome screen), I get these grey lines when I switch to fullScreen mode, even with the ", false" added at the end of the command.
