Hello,

I have a .x model that I have stuck into my game and I got the transparent textures to work using this code:



The problem I am having is that when the plant is seen against the sky I get weird blue jaggies around the edges of the plant:



Is there any good way to fix this? The texture file is a .tga file, but I also tried converting it to bmp.

Thanks!
Matt

SET OBJECT TRANSPARENCY has lots of different flags other than 1

Help from Update 6 RC10 in case you have not upgraded;

Quote: "
0 - draw first no alpha
1 - draw first with alpha masking
2 and 3 - draw second which overlaps solid geometry
4 - draw second alpha test (only render beyond 0x000000CF alpha values)
5 - water line object (seperates depth sort automatically)
6 - combination of 3 and 4 (second phase render with alpha blend AND alpha test, used for fading LOD leaves)
"


Try each one until you find best one. 4 and 6 should be best options.

Ideally you should not use TGA but use PNG with multiple levels of alpha transparency.

Alternatively you can turn off smoothing on the texture and use a filter value of 1 in SET OBJECT command, tree will look blocky close up but it it sometimes more acceptable.

Boo!

Many thanks! I was using the built-in help so I did not see the additional flag info. Where can I find this new documentation? I have dbpro 5.9, I believe.

Currently there are only beta versions of new V6 update. Look at top of DBPro forum for RC10 - this is proposed to be almost the final version. There are only a few known bugs in it to do with collision on instanced objects, but if you don't use them you should be ok.

Final version of U6 is probably a good few weeks away as a completetly new help system is being introduced which makes things a lot clearer. Newsletter due next week is to show a sneek preivew of what they will look like.

Boo!

Thanks again

Just for posterity's sake, I found a value of 2 worked best using a png texture.
