If I use a clip-tool, I can cut the brush to any shape.

All vertexes should be on 64 grid. So danz and digs are disqualified. 

Can we use the func_* to change the architecture at the time of the game, as shown by the onetruepurple? 

I'm not making the rules, go for it. The mo funk the mo better. 

all my vertices are on grid. ;)

Taken from Discord:

Grim_Fandang0: I would say, non 64 grid entities are allowed, kinda lame to not be able to light it properly because light entities are to far from walls

Danz: @Grim_Fandang0 what's the verdict on trigger and clip brushes? Only grid 64 or any grid?
Grim_Fandang0: I would say 64

u]|[KK]|[o: What about rotations? Only verts snapping to grid or rotations allowed?
Grim_Fandang0: verts must snap to grid
Grim_Fandang0: of course rotation hacks are allowed
Grim_Fandang0: but when I open your map file I want to see geometry snapped to grid 64 

All above is right, but if you do everything on a grid 64, you'll get bonus points :) 

Hi. I was wondering: what are the unwritten rules of speedmapping jams/events? Stuff that everyone knows, unless they haven't been part of the community for ever. Skimming this thread gave me the following baseline but I'm not really sure if it's accurate. And as I'd like to get (back) into mapping, I feel like speedmapping is what I have the time to do.

1. Events have theme (which can be "no theme" too) that people have to adhere to.
2. Theme typically comes with a set of limitations (only this wad or only these kinds of textures, everything on a grid, etc.) but it's not absolutely necessary.
3. Limitations can be bent (sometimes) but fewer kudos are awarded for doing so.
4. Interval between even announcement and deadline tend to be a few days or so.
5. Organizer gathers entries and publishes them as a pack.
6. Redoing speedmaps from other people from other events is OK.
7. Finalizing complex, RC-quality maps is not OK.

Does it sum everything up or am I wrong on something? I'm also wondering about the, uhm, expected quality. I assume that the bar is pretty low, correct?

Thanks in advance for your responses. :) 

To answer your questions: yes. 

Welcome back to mapping. No need to rely solely on speedmapping to actually map. You could "remix" one of your favorite maps from the original game.

And another option is go back and try older speedmapping events on your own with a self imposed deadline. i.e. sm189 Doom textures.

Good luck. 

I wouldn't remix original maps now that I've seen you on your YT channel fixing brushes on one of them. With my OCD I'd spend all the time ironing all of the existing kinks and add nothing instead. :S Unless by "remix" you mean "recreate with a twist" and not "build upon".

Either way once I'm done with all the FreeCAD work that I have on my plate, I'll attempt at building something from scratch by randomly selecting theme like this. 

Yup I meant "recreate with a twist"  

Hi guys!

Not sure where I'm supposed to submit my entry for the SM194 event, but I uploaded it to Quaketastic:

Screenshot (Do people usually even provide screenshots for map jams, let alone speedmapping events!)

This is my first ever contribution to a mapping event. My slow mapping speed prevents me generally from participating to any events, but this event happened to align so conveniently with my situation that I just had to participate! The grid 64 rule really helped me lower my standards enough to map faster and settle for less. I still ran out of time, though! xD 

The session has ended and the pack is almost ready to go.

Only waiting for Mugwump to send over 10Mb .bsp with a 18Mb skybox and a music file. 

I probably won't be hosting any speedmap sessions while Jam X is alive... but don't let that stop you from trying yourself!
