I'm trying to make the candle on top of the cake model lit like it is at the end of the official portal levels. Would anyone show me how to do this? I would appreciate it

The candles flame is an env_sprite; the sprites name is 'glow01.spr'.

No matter what I do I can't get it to work, yes I have start on flagged and i've tried a million different setting even tried using env_firesource to ignite and. I've also read up on it on many sites and I can't find anything i'm doing wrong but the fire just doesn't appear.

If I walk where the fire should be it damages me but it is invisible.

Any help would be much appreciated

Set the Render Mode to "Additive"

It still isn't appearing in game, damn I thought that would work.

Make sure that the scale is set properly (and isn't blank or zero), and make sure there is a .spr extension on the end of your sprite's name. I don't know why but it has to have .spr or it won't display.

it was the .spr problem. Thank you very much this has been frustrating me for a while
