Hi everyone !
_ I met a problem with sun flare len in my project. When i used c_trace (or trace) to find that did the sun and camera hit any entity ?, but the c_trace didn't caculate correct . it caculated on the Cube of the Model!

look picture :

The model is between camera and the sun. but the result of c_trace is zero and we can see the sun flare

When the Cube of Model (Double press F11 - the blue buce will appear) is between the camera and sun, c_trace calculate correct. !


see Image clearly :

You can Download my Project with such problem here :

set polygon to the spaceshiop model and thats it.

Thank you !
I'm sorry but I'm a newbie... so... do this Polygon Flag makes my game slower ?
I read from the Manual :
"Only one of the objects involved in a collision should have a polygonal hull. Do not set this flag for moving objects or for animated models."...

and when the flasg Polygon is on, What about the trace_mode of c_trace ? Because I set the polygon but it still like that !

thanks againt !

Setting the polygon of the models MAY slow the game, and it may also
make any existing collisions system you have behave differently.

Give us a look at your c_trace command. It should have the USE_POLYGON flag on
in the command and TRY not to use the USE_BOX flag as it is slow.

Thanks so much !
But when i added some code :



and for my c_trace fucntion :



It still can't solve that problem !
The Trace() used the Box for calculating !

ok ! Thanks !
I solved that problem !
