Magnus Norddahl	8a500a25f5	- rewrite the user shader support for materials - new syntax is to create a 'Material ProcessMaterial()' function	2018-07-15 23:01:40 +02:00
Christoph Oelckers	cce6c9a085	- fixed precision issue with dot product. ... Apparently the shader math is not precise enough to ensure that two supposedly orthogonal vectors are truly orthogonal, resulting in a non-zero dot product	2018-05-24 20:31:44 +02:00
Christoph Oelckers	1266339c0f	- fixed shader compilation.	2018-05-19 21:17:58 +02:00
Christoph Oelckers	3dc6ddbcc3	- check light direction in the shader. ... There are situations where lights on the wrong side of a linedef may be passed and those need to be skipped in the shader code.	2018-05-19 19:20:45 +02:00
Magnus Norddahl	9b7bef59d2	- fixed Intel rendering glitch with uDynLightColor	2018-03-12 21:44:55 +01:00
