I have a particle system modified from tf2's flamethrower effect.
I've set the collision via traces to DEBRIS, which according to the wiki (http://developer.valvesoftware.com/wiki ... onstraints
), it collides with nothing but world and static stuff. This is exactly what I need, because I will have some props to block the player from the fire.
However, as seen in the picture, the particle collides with "invisible entities" on my level. I did not place any entities or brushes at those areas, and I cannot pinpoint what is causing it exactly.
Have anyone encounter similar problem or have experience to share about working with collision via traces?
Is there any way I can enable a debug mode for me to identify what is causing the collision?
Thank you in advance!
