After seeing Luffaren his post for porting toaster to css, I had the idea to do the same for Cathedral. I made an attempt far earlier on this but I didn't do it since entities barely port over. Anyways I think it's time for me to do other things so I decided to start porting it anyways now. I will only port the visuals, not a single entity (except environment_light) will be ported as it otherwise crashes on opening the .vmf Let me start by saying the map is not fantastic gamplay wise, and it's worst problems were of course FPS. This mainly due to the expensive models I created myself. I've come up by the idea of making very cheap LODS which should significantly increase FPS. Gameplay-wise I will try to add more things than it's GO counterpart to make it more interesting. I will have to redo all entities, all triggers, all lights and as I said optimize a lot. Visual optimizing was done already with hint and skip but for so far there's something to do on that aspect, I have done all I can to keep FPS at a playable rate (and it should be much better with the LODS anyways.) I will not say too much from here on, there's not really much to tell anyways. I will try to release ASAP.
