sir fen the usa Posted December 6, 2009 Share Posted December 6, 2009 so im using the flame sprites that i grabbed from the tuts extra cd for a candle flame. the problem i found is that for some reason the candles glass container seems to block the bottom of the flame. i should be able to see the flame through the transparent glass. must be some parameter setting i missed?

Hash Fellow robcat2075 Posted December 6, 2009 Hash Fellow Share Posted December 6, 2009 interesting. Just to try ... there's an "additive" transparency property or something like that for sprites. Try changing that. Also try Streak particles instead of sprites. Quote Link to comment Share on other sites More sharing options...
sir fen the usa Posted December 6, 2009 Author Share Posted December 6, 2009 could not seem to find the sprite transparency additive. but i took another tut and added a simple dbl sided transparent model and my candle model. the simple tranparent model is fine and you can see the flames through it. but my candle model just reflects the flame and you cannot see through it.

Eric2575 Posted December 6, 2009 Share Posted December 6, 2009 I would guess it might have something to do with the refraction value of the glass - that is if you set a value for it. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted December 6, 2009 Hash Fellow Share Posted December 6, 2009 I got the problem the first time I tried it, but can't repeat it. try this sample project set your render tab to "Use camera settings" (corrected PRJ below) "Additive color" is there under Sprite emitter, although it's not a factor in this case. refraction is not an issue either.

sir fen the usa Posted December 6, 2009 Author Share Posted December 6, 2009 i did not change the refraction. you can only change the values from 1 to 2 or anything between. made no difference. im going to try another method. Quote Link to comment Share on other sites More sharing options...

sir fen the usa Posted December 6, 2009 Author Share Posted December 6, 2009 yes your sprite emitter works. i think its because im using streaks not sprites... Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted December 6, 2009 Hash Fellow Share Posted December 6, 2009 missing the glass model? Sorry. spritetest.zip Quote Link to comment Share on other sites More sharing options...
sir fen the usa Posted December 6, 2009 Author Share Posted December 6, 2009 here is one that works with the sprite emitter. although it looks like i could melt steel with it i will have to work on some parameters. lol Quote Link to comment Share on other sites More sharing options...
Douglas Ferrin Posted December 7, 2009 Share Posted December 7, 2009 I had that same problem a couple of years back. I thought maybe it was becqause I had double thick glass (two planes instead of one) but I just did a test and that doesn't seem to cause it. Back when I did it there wasn't any refraction property in AM yet. Finally I decided not to worry about it because people were looking at the bottle and not the fire anyway, but it bugged me to no end. I hadn't tried fire with v15 until tonight and it seems to work fine. A couple of things I can think of are: what version are you using? Another is that I too took my emitter from an AM tut - campfire one - tonight however I made my own. Good Luck. Doug Quote Link to comment Share on other sites More sharing options...

Doug were you or are now using sprites or streaks? im on ver 15.0g it seems that sprites work but im having a hard time getting them took look right. i love the streaks flame but they just dont seem to show through a model, transparent or not. it would be nice to have a generic flame material....

Douglas Ferrin Posted December 7, 2009 Share Posted December 7, 2009 Yeah, I think I was using streaks. But tonight I did it with sprites. It does take a bit of doing to get them to look just right. Try some different shaped image files, and combine them with other image files, maybe. Try different transparencies. Try diminishing them over time in terms of size and opacity. It seems like a limited medium (particles) when you start, but then you learn to juggle them around to great effect. Here's an explosion I made the other day - being a bit more experienced now, it took me 2 or 3 hours. >>but im having a hard time getting them took look right You mean look right in just in a fire sort of way, or are you still having trouble with the glass?

Douglas Ferrin Posted December 7, 2009 Share Posted December 7, 2009 Here's the explosion project if you want to get a look at it. I think it's pretty cool. Doug Use the zip file Explosion_send.zip Quote Link to comment Share on other sites More sharing options...
Douglas Ferrin Posted December 7, 2009 Share Posted December 7, 2009 >>just dont seem to show through a model, transparent or not. I don't know. That sucks. Try making everything from scratch in a new prj. Just enough to see where it goes wrong. For example, make a vase. Make a transparent emitter object in the vase. Attach a sprite material to the emitter. Put some glass in front of it (not the glass you've already used). Try double-plained glass against single planed glass, flat against round. See what happens.
