Hi, I want to make some grass to use in my game.
I made a nice texture which is either alphamapped or a plain 24-bits texture with black in it for transparency.
Now if I load my object and I want to make it transparent with the SET OBJECT TRANSPARENCY and the SET IMAGE COLORKEY commands, nothing happens at all, my black texture is just black.
When I use my alphamapped texture on the object and use the SET OBJECT TRANSPARENCY it IS transparent but! some blue lines appear around my 'cut-out' texture.
Is there any way to get a proper transparent texture going?

On another note:
I used another texture for some other object, and I used colors varying from grey-black to black and I found that some parts of this texture were transparent using the SET OBJECT TRANSPARENCY command, however the parts that were transparent were not truly black.
Anyway, I copied parts of this texture onto my grass texture and surprisingly enough they didn't appear transparent anymore even though they were transparent before...
I need some help

are you using this object in an actual scene or just rending with the standard DB blue background?

Also you should upload the image so we can test on our own objects or at least post a screenie of how bad the blue lines are....

one thing to watch for with transparency is STRAY pixels in the image (around the edges of the image), a lot of times these strays are very light and very hard to see even magnified... They can cause an artificial ghosting around the transparent object in DB and are especially noticeable when only rendering to the typical blue background...

good luck and hope this helps....

To answer all your questions, I tried both the commands you've given and both did not work. I also rendered it in both a real scene and just with the blue background.
The texture I use can be found at http://img436.imageshack.us/img436/6744/grass5uu.png
And on a side-note: I'm using version 5.2 of DBPro, maybe this has been fixed?

I ran the picture through photo7, got rid of the purple, cleaned up the edges (black parts) and saved it...

modeled a standard plan in milkshape (quicker to load than max 8 on my pc) and exported in x format...

attached shows two screens from DB, one with standard blue background, other with a modified sprite background...

compare these two with yours and let me know if cleaning up the edges works better.....

edit: using 5.2 myself.....

only used

SET OBJECT TRANSPARENCY 1, 1

on the object....

mipmapping will give those nasty background what i call stroke lines turn mipmapping off for your object.

Ink all over the screen...and dang it! Signature still does not show.
