I know the number of people who might care about this are few but.. When Firefly renders you get a "adding objects" status bar. I was curious why some figures render faster than others regardless of their polygon count. Well I took the slowest ones and reduced their obj to one material and they rendered super quick. So "adding objects" is a material zone calculation. But the question still existed as to why some rendered slower. Then I opened the obj file and found the difference. Some obj files have hundreds of fragmented g/usemtl strewn throught the obj file instead of groupped neatly together. g lHand usemtl SkinHands f 17250/35129 20780/18660 32811/35130 32810/35131 g lForeArm usemtl SkinBody f 32811/35130 32812/35132 32654/25808 32650/25807 g lHand usemtl SkinHands f 20780/18660 17249/35133 32812/35132 32811/35130 g lForeArm usemtl SkinBody f 32812/35132 32813/35134 32655/25805 32654/25808 g lHand usemtl SkinHands f 17249/35133 20777/18658 32813/35134 32812/35132 g lForeArm usemtl SkinBody f 32813/35134 32814/35135 32656/18657 32655/25805 g lHand usemtl SkinHands f 20777/18658 17248/25803 32814/35135 32813/35134 ----------------------------------------------------------- It should more simply say: g lHand usemtl SkinHands f 17250/35129 20780/18660 32811/35130 32810/35131 f 20780/18660 17249/35133 32812/35132 32811/35130 f 17249/35133 20777/18658 32813/35134 32812/35132 f 20777/18658 17248/25803 32814/35135 32813/35134 g lForeArm usemtl SkinBody f 32811/35130 32812/35132 32654/25808 32650/25807 f 32812/35132 32813/35134 32655/25805 32654/25808 f 32813/35134 32814/35135 32656/18657 32655/25805 This can be easily caused my remapping/regrouping, etc etc. A python utility or something for this would be awesome.
