Christoph Oelckers	5ad1d74f62	- added missing shader #define.	2021-02-12 14:55:42 +01:00
Christoph Oelckers	ddc968f607	- disable palette emulation when map global fog is active. ... This doesn't work well together and is pointless anyway as everything needs to be rendered at full brightness. Fixes #99	2020-10-03 18:04:07 +02:00
Christoph Oelckers	f106f35598	- fixed interpolation of palette emulation.	2020-09-23 18:18:23 +02:00
Christoph Oelckers	0461acfc8b	- removed the brightness fudging in the palette emulation shader and always return an alpha of 1. ... The fudging was only needed because fog was still applied on top of the palette emulation so after completely disabling the true color distance attenuation in palette mode it made the image too bright. The alpha needs to be 1 because this is only the texel, not the combined color.	2020-09-21 21:17:23 +02:00
Christoph Oelckers	29a10cabcb	- fixed most issues with palette emulation. ... Brightness is now correct - I have no idea why this factor of 1/0.85 is needed - something must reduce the brightness of the entire scene but I have no idea what.	2020-09-18 22:29:13 +02:00
Christoph Oelckers	3188ff4a79	- tewaked the distance calculation in the shader to improve palette emulation brightness. ... Fixes #393	2020-09-15 22:16:51 +02:00
Christoph Oelckers	aeeec61f39	- fixed light level setup in palette emulation mode.	2020-09-13 20:48:54 +02:00
Christoph Oelckers	95b4340eec	- initial palette shader work.	2020-06-17 12:26:01 +02:00
Christoph Oelckers	5728241c1c	- updated backend from GZDoom.	2020-05-30 23:10:17 +02:00
