Writing a new RFF / map parser for Blood. Got the basics importing. #bloodgame #retroshooter #modding #gamedev

Paint bucket tool. Not convinced I like the UX for this tool just yet. Maybe it should behave more like a paintbrush. #doom #GZDoom #retroshooter #modding #gamedev

It's been a few long, tedious weeks of refactoring. I now have a proper caching layer in front of the graph and reimplemented the scene extrusion from the ground up, so now level edits and scene rebuilds are super fast. #doom #GZDoom #retroshooter #modding #gamedev

Design question. If a user selects a sector, that currently selects both the ceiling and the floor of that sector - the map being 2D and all that. How does one change floor / ceiling heights independently? Or shift texture coords independently? #retroshooter #modding #gamedev

Wireframe on shaded just hits different. X texture offsets seem fixed for DarkForces but Y offsets seem... odd. I must be missing something. #darkforces #retroshooter #modding #gamedev

The state of TESTBASE. Fixed texture scaling and lighting now appears correct (mostly). #darkforces #retroshooter #modding #gamedev

Merry xmas all! Getting towards the tail end of an enormous refactor and it's actually starting to look like an editor. Testing freeform polygon and edge joining tools here. More build engine content soon, I promise! #doom #GZDoom #retroshooter #modding #gamedev

Viewport rendering modes. Pick wireframe, solid, textured and shaded. Picking reimplemented - still refactoring some rendering calls. #doom #GZDoom #retroshooter #modding #gamedev

The state of E1L1. Fixed a lot of issues with UVs. No slopes yet. Starting to rebuild the orthographic view using the same base as the 3D view. #duke3d #retroshooter #modding #gamedev

The state of E1M1. Map now oriented correctly, texture coords and pegging fixed, sector bowties / holes / floating lines handled a lot better, texture assembly via patches almost complete. I have *zero* idea why the texture STEP2 is rendering this way. #doom #GZDoom #retroshooter #modding #gamedev

A small rant / brain-dump around design. I was under no illusions that doing something like this was going to be technically challenging so not surprising that things have started to get tricky now that I’m going beyond basic map geometry. 🧵 #retroshooter #modding #gamedev

Still a few missing textures but mostly parsing the Marathon map format. If you haven't played Apotheosis X, I highly recommend. #alephone #retroshooter #modding #gamedev

Abusing the universal map format. Hard to make it out but this is Hollywood Holocaust running in Blood and GzDoom (notice I haven't fixed doom coords - tut tut). #duke3d #bloodgame #GZDoom #retroshooter #modding #gamedev

Duke texture indices and rotations fixed. Really need to start looking at those texture coords :) #duke3d #retroshooter #modding #gamedev

Better! Love how the devs were able to nail the SW aesthetic despite the primitive tech at the time. #darkforces #retroshooter #modding

Ok so it *almost* looks like SECBASE? Still a lot of work to get Dark Forces maps look nice. #darkforces #retroshooter #modding

Better loading of Doom textures (still not perfect). Multi-selection editing of textures now supported. #gzdoom

Cross-engine map viewer / editor. Is this a bad idea? Probably! #alephone #eduke32 #gzdoom
