Ian Curtis	7ec7906c0f	Turn off lighting if fixed shading (or no normals) flag is present. Fixes some of the lighting weirdness in scud	2016-04-30 20:32:44 +00:00
Bart Trzynadlowski	48767b2267	Legacy engine: fixed per-vertex fixed shading to incorporate Ian's findings that the intensity value is signed and that fixed shading applies only when lighting is enabled	2016-04-30 16:23:25 +00:00
Ian Curtis	23a5839d46	Daytona seems to use 3 bits for texture transparency, will figure it out later but for now this works	2016-04-30 09:02:38 +00:00
Ian Curtis	30ca1792bb	Fix fixed shading maths	2016-04-30 08:58:13 +00:00

Bart Trzynadlowski	57d5bc8367	Legacy engine: preliminary per-vertex fixed shading. Only limited testing with LA Machineguns (appears to work), Sega Rally 2 (appears okay), and Scud Race (fixes expert course bridge but not other mis-colored polygons).	2016-04-29 03:56:06 +00:00
Bart Trzynadlowski	34e8f00382	Legacy engine: extracting fixed shading component (but still can't use it because unsure of how to activate)	2016-04-28 13:18:15 +00:00

Bart Trzynadlowski	6d9426759b	Fixed texture enable bit (fixes Star Wars light sabers and Sega Rally 2 cones) and added a hack for (and more comments about) color modulation. Scud Race, Sega Rally 2, LA Machineguns, etc. look correct now, but Fighting Vipers 2 shadows are no longer dark enough. Other bugs may exist.	2016-04-04 03:50:24 +00:00
