Alpha masked models are supported --- texture transparency for trees, brushy stuff, etc.

Screenshot

See it in action in Quakespasm "Spiked" by downloading this mod and extracting to c:/Quake/alpha_mask.

Start Quakespasm and do "game alpha_mask; map start" and look at the lavaball in the HARD hall way.

This is how they work:

1. You'll need QME 3.1 to set the flag. Download QME 3.1 shareware

2. The flag is 0x4000 (same as Hexen 2). Here are screenshots:

Holy Crap
Holy Crap this is awesome. All the cool stuff of Darkplaces but still twisty water. 

This is all very cool. Thank you spike. 

 

Any chance of implementing lit water in this? It would be a huge incentive for mappers. 

 

Thank you so much Baker for your effort to show examples, this is very easy to follow.

-If someone not using QS-spike attempted to play a map that had weather enabled via the worldspawn key option, would they just not see the effects or would they receive console spam/errors?

Anyway, this is completely amazing to see these type of effects in my favorite engine! 

Just no effects. No console print or anything. 

So, I've made a new snow particle texture (tga only yes?). Where do I put this tga?

Is there documentation for the FTE particle system? (I assume it works basically the same as this?) 

but um, probably not desirable to inline as a blob.

One idea is - would Spike/others be interested in uploading vaguely stable versions (as tarballs with a readme.txt) to this directory ?
https://sourceforge.net/projects/quakespasm/files/Community/
and we can link/document it in some form ?

If so, pls create a sourceforge account and i will add you to the project and you can upload to this directory.

This would probably be easier for everyone than the alternative; preparing patches and chatting to Eric and Oz about committing single features to main. Cheers 

so if I have image bensnow.tga, i can dump it in the particles folder, then enable it by using

texture "particles/bensnow" in the definition in weather.cfg 

 

 

 

I can't immediately tell from the documentation:

Let's say I wanted 4 different rain settings for the same bit of sky (off, light, medium, heavy) - I assume I'd need to create a separate particle definition for light, medium and heavy. Can I disable/enable particle emission from the sky texture, mid-game, via QC? Can I change which particle definition the sky texture uses mid-game, via the QC? 

to use from qc, r_particledesc "weather classic" or call particleeffecnum("weather.te_rain") so the engine knows which config to use, then use the particle[rain|snow] builtins as normal.

without qc changes option 1) use a texture called skyrain or skysnow, in addition to the r_particledesc thing so that this config is actually used (this is more for people to add stuff to existing maps).

without qc changes option 2) add a worldspawn field called "_texpart_TEXTURENAME" with value "weather.tex_skysnow" or "weather.tex_skyrain"

without qc changes option 3) an equivelent console command: r_partredirect tex_TEXTURENAME "weather.tex_skysnow"

note that without qc, you need to restart the map for it to take effect.

on the other hand, if you wanted to emit particles from models, use r_effect (which can optionally hide those models too).

to override trails defined by model flags, you can use the r_trail command.

weather effects that leave decals are probably overkill

one option is to spawn a particle from qc that emits other particles that leave trails. emitting such trail emitting emitters from surfaces is definitely overkill.
