drfrag666	1b7312c0d0	Revert "- check light direction in the shader." ... This reverts commit e9f7383279. It was not needed in the old version.	2018-05-25 20:38:26 +02:00
Christoph Oelckers	b3da533033	- 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 (cherry picked from commit cce6c9a085)	2018-05-24 20:45:17 +02:00
Christoph Oelckers	3703132794	- fixed shader compilation. ... (cherry picked from commit 1266339c0f)	2018-05-23 10:22:12 +02:00
Christoph Oelckers	e9f7383279	- 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. (cherry picked from commit 3dc6ddbcc3)	2018-05-23 10:22:11 +02:00
