Hi All,
Sorry it has taken me so long to respond but I have been mulling over in my head, what to do about this situation. If I create all the buildings separately  then when someone thinks they can load them all in Poser, and it crashes then I am the bad guy. This model was designed to be an entire city block. If I leave out some of it, then it will seem incomplete. I suppose I could remove the 24 different weed types with their respective transparency maps as well as reducing the amount of maps in general. As an example the concrete walls have ten different maps to give a natural variation in texture. That same thinking is woven through out the entire project. If i remember correctly there were 268 maps with 285 materials. That is what Poser is having a heart attack from.
After spending the better part of 6 weeks working on this model it was non the less a huge let down  to me as well. Oh if only Poser would hire some good programmers to bulk up the software. But I am expecting way too much I think, as I am used to working in multi dollar programs such as Maya, 3D Studio max and Cinema 4D.
I am open to suggestions as to what to do as well as what you think I could loose in the model to reduce the load on Poser. My first thought is to remove the weeds. That in itself might be enough to make the difference. I spent who knows how long placing thousands of them individually. I suppose I could make a set of plant to sell as a separate product so if you wanted to go that route then so be it.
As far as poly gon reduction software it always tears the UVW maps and I would have to start from scratch on that as well.
Have to say I am at a loss as to what I should do.
Well enough rambling for now.
Kind regards, Tom

After I hit post it occurred to me that I could assign just one map to all of the weeds which would be better than having no weeds at all. Hmmmmmmmmmmmmmm
We shall see, what we shall see.

Still would love to hear your ideas.
