to kaom.The importproblem in bryce is well known and i have it too.cant import *.obj files that are larger than about 12 mb . But in xfrog there is a slider down at the left, that shows you how many polys your tree has.And with that slider you can reduce the amount of polys of your tree, without changing the look of your tree dramatically.just draw him to the left.and if you keep your polys lower than about 120000 bryce has no probs.but maybe someone will solve that d.... imprtprob sometimes
