View Full Version : Glowing transparencies at distance
Apr 30 2003, 17:29
I am using Photoshop 7 to make my transparencies and they work fine.
The only problem is in game there is a line of yellow on the outer boundaries of all my wheels.
When I move away the yellow becomes biggger and biggger until it looks as it my tanks have glowing wheels.
I am using the pencil tool so there are no feather edges on the model.
I have tried changing the vertex and face properties but without any change.
Has anyone else come across this and is there a way round it.

What is the color of the background of your wheels texture?
from what you're saying about the yellow pixels around the wheel, I'd believe that your background is yellow. Try to make the background the same color as the wheels, this way, there should be no problem with the color at the boudary of the alpha mask.

I have tried it with an all back shape.
I have a feeling that the problem is photoshop 7. It is a lot of hasstle for me to d/l a demo version of paintshoppro just to experiment

paintshop pro only saves tga in 24bit.
32bit is required.
can you post a screenshot to show us the problem? I'm running out of ideas as to the cause of the problem. Matbe seing the problem with my own eyes will help.

The black line which is on the outside of the wheel is the actual edge of the image. Everything else is blank (with transparent background)
Not a very good example Im afraid but look at this one.
The image is 256 x 256 32 bit Tga. It has been made in Photoshop 7 with the pencil tool - not a brush which leaves feather edges. The image is all black. Note how OFP renders this with a glowing edge. When you pull the view back the glow gets bigger and bigger.
Anyone else use Photoshop 7?
Did you check that the selection marquee tool is set with a feater of 0 pixel and "antialised" is unchecked? (top of the screen under the menus).
Also check that the part to which you're apply the transparencies are drawn last in OFP (you must make sure the transparent pieces are made after the pieces in the background) one example to explain my meaning: if the blurred rotor texture of a chopper is made before the chopper fuselage is all finished , there can be a problem with the transparency of the rotor hiding the pieces behind it that have been made after the blurred rotor.To make sure that the rotor do not interfere with the rest of the fuselage parts, you only have to cut the rotor (Ctrl+X) and paste it again (Ctrl+V).
This way, the rotor will be listed in the P3D last, and will not interfere with the pieces underneath it, that should be drawn first by the rendering engine of OFP. perhaps you have the same kind of problem with your wheels? selected them and do Ctrl+X and then Ctrl+V to make sure they'll be drawn after the hull of the tank.
Well, If you've checked that, I don't believe that there is a solution to this problem. Look at BIS BMP for an exemple: the front and rear wheels have the same problem when seen against the ground.
So I guess, we could live with it. http://www.flashpoint1985.com/ikonboard301/iB_html/non-cgi/emoticons/wink.gif
I hope this help.

It's a known bug of PhotoShop 7.0. It's using allways background color at transparency edges. Use PhotoShop 6.0 and your problem will be solved. Or download patch at 7.0 http://www.flashpoint1985.com/ikonboard301/iB_html/non-cgi/emoticons/smile.gif
