Subject: [PATCH] Don't lookup fluid state when raytracing, skip air blocks
|
|
|
|
Just use the iblockdata already retrieved, removes a getType call.
|
|
|
|
Also save approx. 5% for the raytrace call, as most (expensive)
|
|
raytracing tends to go through air and returning early is an
|
|
easy win. The remaining problems with this function
|
|
are mostly with the block getting itself.
